French Drain Design Steps, Norman, Oklahoma City, Edmond, Moore

Installing French Drains is what we do most.

Oklahoma Drainage has been installing French Drains, Surface Drains, Sump Pumps and Sod since 1993.

French Drain Design

is just Designing the French Drain Part of a Drainage System.

If you have already Diagnosed Your Water Problem the French Drain Design comes next.

Determine the Depth of the Drainage Trench.

To do this you must first look at the amount of slope involved.

Is the ground where the drainage trench will be located on a slope?  Hopefully it is.

A very slight slope is hard to work with.   The French Drain Trench can’t be very deep.  If it is too deep and you don’t have much slope then water will enter the French Drain and will just sit there.  It won’t move toward the transition pipe which will then take the water to the Exit.

If the slope is good and you can easily tell which way is downhill, then you can dig the drainage trench toward the exit knowing that it should flow well.

You want your drainage trench to run across your drainage problem area.  It needs to be running downhill toward the exit.

The more slope you have the deeper the French Drain can be dug if desired.

If the French Drain Trench is Deeper, it can carry more water downhill toward the exit.  Some of the water will travel in the French Drain Perforated Pipe.  If it becomes completely full then additional water will travel down the trench in the gravel above the French Drainpipe while still in the Drainage Trench.  This is important it you have desire for your French Drain to Handle Flood Prevention Which is more robust than just a Drainage System.

Drainage Systems 

can be made up of one drain or a combination of many drainsDrainage problems can be very complex.   Complex Drainage Problems may require a combination of several different types of drains all inter-connected and working together.  Other times the drainage problem may be simple and straight-forward requiring only one drain or several of the same type of drain connected together.

Surface Drain Installation

Surface Drain Installation

An example of a complex drainage system would be:  A French Drain in the back yard connected to a Surface Drain near a flower bed connected to several gutter downspouts, which are connected to a Channel Drain going across a driveway, which is connected to additional Surface Drain in the front yard, which runs to a Curb Fitting that lets all the water drain out on to the street.

A simple Drainage System might consist of a Surface Drain that is connected to a second Surface Drain which runs to a Pop-up Emitter which lets water drain over the curb and into the street.

An “Exit Point” is the term used for where all the water leaves the Drainage System.  Determining the Exit Point is very critical.  It is one of the first things we do when diagnosing a Drainage Problem.

Drainage Systems can:

1 Keep water away from foundations

A French Drain is best because it can move Surface Water and Sub-Surface Water (water moving underground) away from the foundation.  Many times, less experienced companies install Surface Drains to keep water away from foundations.  This can be a big mistake.  A Surface Drain can’t move or drain Sub-Surface Water.

Surface Drain and French Drain

Also, A Surface Drain often can’t move enough water fast enough and easily becomes overwhelmed during a heavy rain.  A Surface Drain also can’t cover or protect a broad enough area.

Surface Drains should be designed in a Drainage System to be located in smaller Drainage Areas moving moderate amounts of water.  Surface Drains look better than French Drains.

If, “appearance” is more important than Drainage Capacity, Go with the Surface Drain.  Just know what you are getting into and what your expectations should be. One side of a foundation alone, can be over 100 feet.  A 4 inch or 6-inch French Drain is best when protecting a large area such as a foundation.

2.  Keep water away from small or enclosed areas.  This might be a low area just through a gate on the side of a house, or the low area between a flowerbed and the wall of a house or standing water on or near a sidewalk or driveway.

Surface Drain

These types of Drainage Problems are best served with Surface Drains.  A Surface Drain can move water away from a low area that is relatively small.  This can occur in yards, flowerbeds, sidewalks and driveways.  A Surface Drain is designed to move Surface Water away from a problem area to a predetermined exit point.  Surface Drains are available in many sizes.  How quickly they remove standing water is usually determined by the size of the Drainpipe that is connected to the Drain.

Just what is a “French Drain?” 

Many times, people incorrectly use the phrase, “French Drain,” to apply to many different types of Drains that could be used in a Drainage System.  The term is widely used and many times incorrectly connected to “Surface Drains,” or “Channel Drains.”

Connecting French Drain into Surface Drain

Connecting French Drain into Surface Drain

A Surface Drain has a grate that sits on top of a basin.  The basin is underground.  A Drainpipe is connected underground to an outlet on the Drain Basin.

Stormwater Drains through the grate into the Drain Basin.  Once in the Drain Basin, water travels out of the basin through a Drainpipe.  The Stormwater continues downhill in an underground Drainpipe to an exit point.

THIS IS NOT A FRENCH DRAIN!

Surface Drain may come in many different shapes or sizes.  The Drain Grate may be round or square.  Here is a picture of a common Surface Drain.

A Channel Drain is a type of Surface Drain, and many times is installed in concrete across sidewalks or driveways.

HOW TO MAKE A FRENCH DRAIN LOOK GOOD!

French Drains are wonderful and helpful providing many benefits for many years when installed correctly.  I have installed French Drains as far back as 1993, That STILL WORK GREAT AND DO THEIR JOB!

This Blog does not focus on the details of Functionality or Longevity of French Drains, but how to make them look better.

This French Drain was installed in December 2022 in Mid-West City Oklahoma.  At First glance the gravel doesn’t look great, however putting Sod on top of the gravel is the worst thing you can do!  LET ME SAY THAT AGAIN!  DON’T PUT SOD OR DIRT ON TOP OF A FRENCH DRAIN!!

Covering a French Drain prevents Surface Water from going into the French Drainpipe which is underneath the pipe.

Imagine This for example:  Putting Sod or Dirt on top of a French Drain is the same as putting gas in your car by opening the gas cap and then pouring gas on the roof of your car.  A drop or two may find its way into the gas cap but the car won’t run. Well, the French Drain won’t work either.  So, what can you Do?

If your French Drain is in the sun and not in a shaded area, eventually grass will grow over the French Drain.

You may think that grass growing over a French Drain is the same as putting dirt over it, but that is not true at all.  Bermuda grass puts out runners that cover the gravel.  It is like netting.  It becomes what I have termed, “A Thatch Filter”.  The “Thatch Filter” helps keep the water clean that goes into the French Drain.

Think about this! Water Goes through the ” Thatch Filter,” Through the “Gravel,” Through the “Trench Liner,” and Finally Through the “Pipe Filter,” into the perforated French Drainpipe.

In my opinion, this makes the French Drain maintenance free INDEFINITELY!  I have installed French Drains in this manner that have been working great for 30 years this year.  I installed my first French Drain in 1993.

The problem is, If the French Drain is in the shade of if the soil is poor, Grass will never grow over it.  Streaks of gravel in your yard won’t look very nice, right!

Imagination and Artistic Creativity are the answer.  Dress up your French Drain.  As long as You don’t restrict the water flow put something decorative on top of the French Drain.  The following are pictures of just a Few things we have done over the last 30 Years.

FRENCH DRAINS AS PART OF A DRAINAGE SYSTEM OR BY THEMSELVES

A French Drain can be a part of a Drainage System or can stand alone.  A Drainage System is made up of one or several types of Drains connected in sequence moving downhill toward an exit or release point.  What makes up or determines the recipe of a Drainage System depends on the “Drainage Diagnosis.”  Every Drainage System is unique to some degree.

French Drain Trench Going Under Sidewalk

French Drain Trench Going Under Sidewalk

For Example, A four inch French Drain may run across a hillside, transition to solid 4 inch Solid Drain Pipe while running under a sidewalk, then connecting into a 12 inch Surface Drain in a low spot,  Solid Drain Pipe then could continue to a garage foundation where the Solid Drain Pipe changes back to 4 inch French Drain again and runs along the foundation for say 60 feet.

Complex Drainage System

Next the French Drain changes again to 4-inch Solid Drainpipe and continues under a fence to a Pop-Up Emitter which is the exit point.  This again is just one example of a Drainage System with 2 French Drains and one Surface Drain being the main parts.  This would be considered a “Complex Drainage System.”

A simple Drainage System might be a 6 inch French Drain running along a driveway, turning slightly and changing to 6 inch Solid Drain Pipe and continuing to a Curb Fitting as an Exit Point.

FRENCH DRAIN DESIGN

French Drain Design must take into account many variables.  One consideration for a French Drain that many times is missed, is the type of soil.  French Drain Design must take into account the type of soil that the French Drain runs through.  If the soil is “Tight or made up of Clay,

The Gravel or Limestone that is used to fill the French Drain trench may be all that is needed to maintain the integrity of the trench over time.   This means that dirt will not mix in with the French Drain Gravel and clog it up over time.

This is not the case however if your soil is sandy or loose.  A Trench Liner should be used to prevent this type of soil from moving into the gravel of the French Drain.  Trench Liners are relatively inexpensive and are not hard to install.  If you are not sure what to do then install the Trench Liner in the French Drain.

Determining the size of the French Drainpipe

can be difficult.  If the French Drain is not very big and has no Gutter Down-Spouts or Surface Drains connected to it then 3 inch or 4-inch French Drainpipe may be used.  If the French Drain is large or has many gutters or Surface Drains connected into it, then you should use 6 Inch French Drainpipe or larger.

French Drain Pipe Installation

French Drainpipe Installation

French Drain Design

is also determined by the Problem Drainage Area.  If water is moving into the Problem Drainage Area underground (Sub-Surface), then installing a French Drain is a “Must!”  French Drains can move Sub-Surface water as well as Surface Water.  Surface Drains can only move Surface Water.  This is why French Drains do such a good job protecting driveways, sidewalks, and foundations.

Oklahoma Drainage and Sprinkler Repair install French Drains and Drainage Systems in all of Central Oklahoma including Oklahoma City, Norman, Edmond, Moore, Mustang, Yukon, and Midwest City.

French Drain Installation —   French Drains are designed to do a lot of things.  If you have an area that has unwanted water standing in it or running across it, a French Drain can be the answer.

A French Drain is a trench that runs across the Drainage Problem Area.  A French Drainpipe is placed in the bottom of the trench.  The French Drain Pipe is perforated with thousands of small holes.  In most cases the Drainpipe has a nylon soc around the pipe to act as a filter for the French Drain.

The French Drain trench is then filled with some type of small rock or stone.  We typically use crushed 1 inch Limestone to cover the French Drain Pipe.  The dirt that was dug out of the trench is taken away or spread out around the French Drain.  The Limestone replaces the dirt and fills the French Drain Trench all the way to the surface.

Oklahoma Drainage Recently installed a Drainage System in Nichols Hills.  The Drainage System was made up of a 4 inch French Drain starting in the back yard.

It ran between the garage and the pool.  Several gutters were connected directly into the French Drain.  From this point, we expanded up to a larger 6 inch Drain pipe to handle the added water into the system from the gutters.  In several places the French Drain had to run through areas where Sprinkler Pipes were in the way.  We had to re-rout all the Sprinkler Pipes and Wires under the French Drain.

Oklahoma Drainage — Installing – French DrainsSurface Drains – Channel Drains – Sump Pumps

Servicing all of Central and Western Oklahoma since 1993.

When Installing a French Drain as part of a Drainage System, there are many things to consider.

What is the primary source of water coming into the problem drainage area.

Are there secondary sources of water entering the area.

What are they and how many.

How fast does water enter the area and how often.

What are the potential exit points for the water,  Where do we want to take the water too.  Is there more than one potential exit point to increase drainage capacity.

Does the customer want a Drainage System or a Flood Prevention System and does he understand the difference.

 

Oklahoma Drainage and Sprinkler Repair

recently diagnosed a Drainage Problem in South Oklahoma City.  The Homeowner had a sump Pump in their basement that was fed from a French Drain outside the Basement Wall.

The French Drain was 14 feet down along the Stem wall of the house.  The French Drain Pipe was cheap and had collapsed.  We brought in a Mini Excavator and dug up the pipe and replaced it with Durable ADS 4 inch perf/soc French Drainpipe.  In the end, we were able to dig up the pipe and replace it.

A French Drain is completely different from a Surface Drain.  A basic French Drain consists of a Perforated Drainpipe in the bottom of a trench.  The Drainpipe should have a neoprene sock around the Perforated Drainpipe.   This is to ensure that the Drainpipe does not become clogged.

The dirt that was taken out to make the trench is hauled away.  It is replaced by some type of small stone or gravel depending on what is desired or available.  I prefer crushed 1 inch limestone.  It is the most economical option in my area.  Pea Gravel or some other type of small stone can work just as well.

Limestone or Gravel

The limestone or gravel is placed in the trench on top of the perforated Drainpipe and filled all the way to the surface (ground level).   In some cases where the French Drain needs to be deep or is being placed in sandy soil, a special trench liner must be placed in the trench before the perforated Drainpipe or the Gravel are installed.  This helps maintain the integrity of the trench over time.  It also increases the cost of the French Drain and the amount of time to install it.

French Drain

is designed to handle a large volume of water and cover a large area. The Drain is anyplace the trench goes. It has many applications and can be used in many situations.  It can be installed by itself or incorporated into a Drainage System with Surface Drains or Gutter Down-Spouts connected to it.
The main downfall of a French Drain is that they, for the most part aren’t very pretty.  They don’t look very nice in a yard once they are completed.
Depending on the area the French Drain is installed and the type of grass around the French Drain, will dictate whether grass grows over the limestone.  Grass can grow up and through the gravel in the French Drain over time eventually covering the gravel.  This is Ok.  It won’t have a measurable effect on the performance of the drain.

Don’t Cover a French Drain with Dirt

DONT COVER THE GRAVEL IN THE FRENCH DRAIN WITH DIRT.  THE FRENCH DRAIN WON’T WORK IF THE TRENCH IS CLOGGED WITH DIRT.  DON’T EVEN INSTALL IT IF YOU ARE GOING TO COVER IT UP WITH DIRT.

What is a Drainage System?

Simply put, a Drainage System is one or a group of underground Drainpipes that take water away from a place that has water standing on it or flowing across it.  The water that is in the problem area, can be causing damage or may be inconvenient or both.  (Usually Both)

A simple Drainage System is a Drain for the water to enter, a Drainpipe to move the water away from the Drain, and an Exit Point for the water to be released out of the Drainpipe.

Drainage Systems quickly can become more complicated.  Considerations must include:

How does the water get to the problem area?  There may be one or many sources.

Water Sources:

1.  It falls from the sky directly

2.  It flows downhill over the surface (surface water)

3.  It flows underground under the surface (sub-surface water)

4.  It flows from the edge of a roof ( There may be many roofs near the problem area, neighbors etc.)

5.  It flows from a gutter downspout

6.  It flows over the edge of a gutter because the gutter is too small is is clogged

7.  It flows up from the ground (seeps and springs are common in Oklahoma)

8.  It flows from a sprinkler system use ( yours or your neighbors)

9.  It flows from a leaking pipe ( water mains, water meters, water lines, sprinkler pipes, sprinkler valves)

There are other reasons for Drainage Problems, the above reasons are just the most common.

Once the number of water sources is determined, a rough estimate of the amount of water that needs to be drained away on average must be estimated.  This can be simplified down to “SMALL, MEDIUM, OR LARGE AMOUNTS OF WATER TO BE DRAINED AWAY.

Diagnosing Drainage Problems

You don’t have to be an engineer trying to calculate fluid dynamics.  Experience at diagnosing drainage problems helps however.  How much water needs to be moved will help determine the type and size of the Surface Drain or French Drain that needs to be installed.

It also helps to determine the size of Drainpipe required for the Drainage System.  A good rule to follow is, “If in doubt, install a larger Drain and Drainpipe.”  Unused Drainage Capacity is better than property damage caused by a Drain that is overwhelmed by too much water.

For home and small business use typical materials used are:

6 inch, 9 inch, and 12 inch Surface Drains

3 inch, 4 inch, and 6 inch Drainpipes

3 inch, 4 inch, and 6 inch French Drains

French Drains move more water than Surface Drains —

French Drains move Surface Water and Sub-Surface Water

Surface Drains move Surface Water only

Surface Drains look nicer than French Drains in most cases

Drainage System

Once the type and number of drains is determined and what size Drainpipe will connect them, an exit point must be selected.  (Where is the Drainage System going to take the water to and release it?)

Installing Drainage Curb Fitting for a French Drain in Norman

Installing Drainage Curb Fitting for a French Drain in Norman

The Drainage Curb Fitting is installed when the desired exit point for the French Drain will release the Drainage Water into the Street.

A Drainage Curb Fitting

is rectangular in shape and made to be installed through the curb.  A small section of Curb is cut out with a concrete saw.  The Section is a few inches wider than the Drainage Curb Fitting.

We then install new concrete around the curb fitting.  Once the concrete has dried, the Drainpipe coming from a French Drain or Surface Drain is connected to the Drainage Curb fitting and then covered with dirt.

The Drainage Pop-Up Emitter

is connected to the end of a Drainpipe.  It is downhill from a French Drain or a Surface Drain.  It is a small release basin with a green pop-up lid.  When releasing water, it pops up about an inch to release the water from the French Drain or Surface Drain.

When the Storm Water

has moved through the Drainage System and out of the Pop-Up Emitter, the green lid closes back to its original closed position.  The emitter is designed to release water out into a yard or down a hill or other desirable Drainage Exit Point where there is no curb.

French Drain as Part of a Drainage System

A French Drain is one part of a Drainage System.  A French Drain can be connected to other types of Drains or Gutter Down-Spouts and then run through Drain Pipe to an Exit point where the water is released.

A Drainage Exit Point is the area where water goes to be released when it comes out of the Drainage System. The two most common exit points for a Drainage System are a Pop-Up Emitter or a Curb Fitting. A Pop-Up Emitter is a Fitting on the end of a Drain Pipe that has a lid that pops up and releases water. When water drainage is complete, the lid shuts back.

French Drain is completely different from a Surface Drain.  A basic French Drain consists of a Perforated Drain Pipe in the bottom of a trench.  The Drain Pipe should have a neoprene sock around the Perforated Drain Pipe.   This is to ensure that the Drain Pipe does not become clogged.

Haul away the excess dirt

The dirt that was taken out to make the trench is hauled away.  It is replaced by some type of small stone or gravel depending on what is desired or available.  I prefer crushed 1 inch lime stone.  It is the most economical option in my area.  Pea Gravel or some other type of small stone can work just as well.

French Drain Design –

Before you begin.

Identify the Problem Area

This is very important.  You don’t want to underestimate the size or scope of your problem.  Your French Drain Design needs to address everything that it can help with or improve. You want to get things wright the first time if you can.

Identify the water sources to your problem.

Most of the time there is more than one water source to your Water Problem.  There can easily be several ways that water is getting to the problem area.  Usually, you have a Primary source and one or several Secondary Sources.   In Rare occasions two or more primary sources may need to be dealt with.

Identify water Movement, Speed, and Volume.

Determine if you are dealing with Surface Water or Sub-Surface Water or Both.

Click on the link above and I will Explain How to do this without using advanced Mathematics or Engineering.  No Multiple Linear Regression Needed Just Common Sense.

Determine If you want a Flood Prevention System or a Drainage System.

This will have a Profound Effect on the French Drain Design.

Decide if you can physically handle the installation of a French Drain.

If you have never done this before you really need to read this.  Oklahoma Drainage has installed French Drains since 1993.  I always recommend digging the French Drain by hand.  Using a Trencher ( a machine that digs ditches) is a bad idea for many reasons.  My Crew and I have literally dug thousands French Drains and Drainage Systems.

If using a digging machine is necessary, we always use a Mini Excavator, never a Trencher.  Using a Mini X as I call it takes a tremendous amount of skill and practice.  It is far beyond the capability of a Weekend Warrior or a Confident Brother-in-Law.

Determine the Pipe Size needed for the French Drain and other Drainage Intakes.

Decide how large the Transition Pipe needs to be.

Determine the Exit.

Identify the French Drain Location

Make a decision on the Width and Depth of your French Drain.

Decide if other types of Drains should be connected to a French Drain to handle Secondary Water Problems.

Finally Decide What to do with the Displaced Dirt.  You will have leftover Dirt.  What are you going to do with it?

This means asking yourself where you want to take the unwanted water to.

French Drain Design Edmond.    French Drains are designed to do a lot of things.  If you have an area that has unwanted water standing in it or running across it.  A French Drain can be the answer.

A French Drain is a trench that runs across the Drainage Problem Area.  A French Drainpipe is placed in the bottom of the trench.

The French Drainpipe is perforated with thousands of small holes.

In most cases the Drainpipe has a nylon soc around the pipe to act as a filter for the French Drain.

The French Drain trench is then filled with some type of small rock or stone.  We typically use crushed 1 inch Lime Stone to cover the French Drainpipe.  The dirt that was dug out of the trench is taken away or spread out around the French Drain.  The Limestone replaces the dirt and fills the French Drain Trench all the way to the surface.

Oklahoma Drainage has been installing French Drains since 1993.  We also install Fescue Sod and Bermuda Sod by the pallet as well.  A pallet of sod will cover about 450 square feet.

Oklahoma Drainage also installs Surface Drains of all kinds including Channel Drains in Driveways or 12 inch, 9 inch, and 6 inch Drain basins in yards and sidewalks and along driveways.

 

Sorry I got sidetracked.  Back to talking about French Drains.   French Drains keep water off of Foundations, Sidewalks, and Driveways.

THREE BAD THINGS CAN HAPPEN WHEN WATER SITS AGAINST CONCRETE.

  1. Concrete can break down and deteriorate from temperature change when the water freezes and thaws.  Lots of cracks can occur.
  2. Concrete can be de-stabilized.  Supporting soil can be washed away or removed.
  3. Mold!!! Yikes!!  Mold needs water.  Water against a foundation or saturating it is definitely a risk for mold to occur.  Mold development can be a very small issue or it can be a Huge Problem.  If Black Sludge starts to appear on top of ground near a foundation, action should be taken.  I have seen extreme mold situations where a home had to be condemned.  Again, this is very rare, but it does happen to good people.

In the pictures below, water was running across the walkway and into the pool every time it rained hard.  We pulled up the necessary stones on the side that the water was coming from and put a French Drain underneath.  A trench liner was utilized as well as a filter around the perforated French Drain Pipe.

French Drains can be decorative and be made to look nice.  As shown above, they can be placed under walkways or had designer stones placed on the gravel that fills the French Drain Trench.

Covering a French Drain with dirt is a bad idea.  Water can’t get into the drain through the stones if it is clogged with dirt.  If you are more concerned about how it looks over what it does, then don’t install it in the first place.  French drains can move a lot of water and protect property such as foundations, sidewalks, plants, yards just to mention a few things.  If you don’t like how a French Drain looks then change it.  Put Steppingstones on top of it, use river rock to improve the look, You are limited only by your own creativity.

When water come in contact with the French Drain, it seeps down through the stones and into the French Drain Pipe.  It then flows through the Drainpipe to the exit point.  Typically, a French Drain will have two possible exit points.   The First is called a Pop-Up Emitter.”  It is a Green Lid on top of a release basin for the French Drain.

French Drains are designed to move large amounts of water.

A French Drain moves water away from the Drainage Problem area from the Surface like a large Surface Drain.   But also below ground, or sub surface.  Most people don’t take into account the water that flows to a problem area underground.  Sub surface water flow is not eliminated by a Surface Drain.  A French Drain can move away water that is below the surface of the ground and drain away water that is on the surface too.

French Drain Installation

Oklahoma Drainage and Sprinkler Repair designs and installs Drainage Systems. Water Drainage is a big concern to homeowners and small businesses.  Standing Water from Storm-Water runoff can cause all kinds of problems.  Concrete in driveways, sidewalks, and foundations can be damaged.  Prolonged Drainage Problems allow mold to occur along with deterioration to plants, trees, and property.

 

Just what is a “French Drain?”  Many times people incorrectly use the phrase, “French Drain,”  to apply to many different types of Drains that could be used in a Drainage System.  The term is widely used and many times incorrectly connected to “Surface Drains,” or “Channel Drains.”

A Surface Drain has a grate that sits on top of a basin.  The basin is underground.

A Drainpipe is connected underground to an outlet on the Drain Basin.  Stormwater Drains through the grate into the Drain Basin.  Once in the Drain Basin, water travels out of the basin through a Drainpipe.  The Storm-Water continues downhill in an underground Drainpipe to an exit point.

THIS IS NOT A FRENCH DRAIN!

A Surface Drain may come in many different shapes or sizes.  The Drain Grate may be round or square.  Here is a picture of a common Surface Drain.

A Channel Drain is a type of Surface Drain, and many times is installed in concrete across sidewalks or driveways.

 

A French Drain is completely different from a Surface Drain.  A basic French Drain consists of a Perforated Drainpipe in the bottom of a trench.  The Drainpipe should have a neoprene sock around the Perforated Drainpipe.   This is to ensure that the Drainpipe does not become clogged.

The dirt that was taken out to make the trench is hauled away.  It is replaced by some type of small stone or gravel depending on what is desired or available.  I prefer crushed 1 inch lime stone.  It is the most economical option in my area.  Pea Gravel or some other type of small stone can work just as well.    The lime-stone or gravel is placed in the trench on top of the perforated Drainpipe and filled all the way to the surface (ground level).

In some cases where the French Drain needs to be deep or is being placed in sandy soil, a special trench liner must be placed in the trench before the perforated Drainpipe or the Gravel are installed.  This helps maintain the integrity of the trench over time.  It also increases the cost of the French Drain and the amount of time to install it.  I install a trench liner in a French Drain Every time.

French Drain Setup

 

French Drain InstallationFrench Drains are designed to do a lot of things. If you have an area that has unwanted water standing in it or running across it, a French Drain can be the answer.

A French Drain is a trench that runs across the Drainage Problem Area.

Yukon Installation

We just finished a 4 inch Drainage System in Yukon

on. It was a complicated system to install. It utilized 4 inch French Drain in the flower beds, 12 inch Surface Drains on the side of the house, 6 inch French Drain along the garage foundation with 2 Pop – Up Emitters in the back yard and 3 Curb Fittings in the front. First we installed 4 inch French Drain in the flowerbeds on both sides of the front door. We connected 4 inch solid Drainpipe into the French Drain and ran them underside walk to the curb. Next we cut the curb with a concrete saw and installed 3 curb outlets for 3 separate French Drains.

Next

we installed 4 12 Inch Drain Basins with grates along both sides of the house continuing with Drainpipe  running to the Pop-Up Emitters on the back fence. Finally we completed the Drainage System by installing a long run of 6 inch French Drain down the side of the garage foundation. Installing the French Drains in the flower beds was the most difficult and took the most time. Each French Drain took over a ton of crushed limestone to fill the French Drain trench. The Six-inch French Drain took even more limestone.

Hard rain in Oklahoma is common.  Many homes and businesses have drainage problems. Standing water from storm water run-off  can cause damage to grass, trees and shrubs, not to mention foundations, sidewalks and driveways. Oklahoma Drainage   can design and install a drainage system that may be complex using several types of drains, or basic using just a French Drain or a Surface Drain.  It depends on the customer’s needs.

 

Today we installed a Channel Drain.   It takes a lot of attention to detail.  Channel Drain installation takes several specific steps.  It is a slow process that takes confidence and experience.  I was able to train a couple of our guys on the complete process.  They learned a lot but are nowhere near ready to solo yet.

We can schedule a free estimate for a drainage system.  A French Drain can be an important part of a Drainage System.  A Drainage System is one or several types of drains connected to an exit point, were the unwanted water is to be released.   A French Drain may be connected to a Surface Drain which in turn may be connected to a gutter down-spout, or Channel Drain.  All the different drains are connected under ground by drain pipe to a Pop-Up Emitter or a Curb fitting to release the water.

What goes into a Drainage System depends on the individual Drainage Problem.  Some Drainage Problems are Simple and need only one type of Drain Connected to an exit point.  Other Drainage problems require  a more complex solution.

FRENCH DRAIN CONNECTED TO GUTTERS

Many different types of Drains can be hooked together by one Drainpipe.  The Drainpipe then running to an Exit Point makes up a Drainage System.

One common type of Drain used in a Drainage System is A “French Drain.”

Many times, a French Drain is installed close to a building foundation or in a low area next to a home or business.  This puts the French Drain in close proximity to Gutter Down Spouts.

Connecting Gutter to french Drain

Connecting Gutter to French Drain

Rather than have water come off the roof and out the Down Spout and on to the ground below, many times it is much better to tie a Gutter Down Spout Directly into a French Drain or nearby Drainpipe depending on the Drainage System Design.

Gutter Downspouts

Connecting The Down Spouts Directly into a French Drain is much more efficient and causes suction to occur in the French Drain.  Connection of Gutter Down Spouts to a French Drain makes the Drainage System work better.

Connecting Gutter into French Drain System

One Problem with connecting Gutter Down Spouts into a French Drain is overwhelming the Drainage System with too much water.

Three Gutter Down Spouts is usually OK to connect into a French Drain.  More than 3 Down Spouts can be too many.

The Drainage System Design should also take into account the size of the French Drain and the Gutters.  If you have a large long French Drain or over-sized gutters, the number of Gutter Down Spouts connected into the French Drain Should be reduced.  This problem can usually be solved by increasing the size of the French Drainpipe.  This usually means moving up from a 4-inch French Drainpipe to a 6-inch French Drainpipe.  Four inch is the most common size of French Drainpipe.  If you have more than 3 gutters Down Spouts to connect, you should move up to a 6 inch French Drainpipe.

Designing a French Drain or a Drainage System

When I talk to a potential customer while doing a Drainage System estimate, I take a lot of things into consideration.

First, I have the Customer show me where water is standing or where it is going that it shouldn’t.  This is part of defining the specific problem area.  Sometimes the Water Problem Area is larger and more involved than the customer realizes.

Once the Water Problem Area is clearly defined, the next step is to determine how the water is getting to the problem area.  Many times there is more than one Water Source to the Water Problem area.  A big mistake in Drainage System Design is to stop once the most obvious  Water Source is found.

A Drainage System Designer must be a detective to some degree.  For Example:  Water running down the hill and onto the back patio might be the most obvious water source.  Sub-surface water or a neighbor’s new gutter downspout could also be contributing.  Most of the time water gets into the problem area from more than one source.

Channel Drain Across Driveway

French Drain Connected to a Channel Drain across the Driveway

Next you must decide where to take the water.  This is determining an Exit Point for the Drainage System.  If possible, you want your exit point to be downhill from the problem area.  If it is up hill in all directions from the problem area, then the only solution is a Sump Pump.

Once an exit Point is determined, you must ask yourself if there is any way to install two exit points.  Usually this can only work when an exit point can work on both ends of a Drainage System.  The benefit of two Exit Points in a Drainage System is it greatly increases the water capacity for the Drainage System.  It can move much more water faster during a heavy rain than a system with just one Exit Point.  Most Drainage Systems can only utilize one Exit Point.  In 21 years of Drainage System Installation,  I would say 10% of our Drainage Systems have two Exit Points.

Popup Emitter to release water from a French Drain in Yukon

Next we have to decide what type of drain to install in the problem area.  If it is a small area with one water source, usually a Surface Drain is best.  If the water problem area is large with one or several water sources, a French Drain is usually installed.

If you have several problem drainage areas, you must use larger Drainpipe if you want to connect them together to one exit point.  Large French Drains should have their own exit point without attaching other Surface Drains or Gutters to them.  It is very common to connect too many drains or gutters into a Drainage System.  A hard rain can overwhelm the Drainage Systems Water Flow Capacity.  When that happens, water backs up and the problem area floods.

French Drain connected into Drainage System

I just shake my head when I see 3 French Drains and 5 gutters connected into one exit drainpipe. I see this type of design all the time.  Why spend money for a Drainage System that won’t work?  Lots of Cheap Builders and Fly-By-Night Drainage Companies cut corners on Drainage Systems and French Drains on new home construction.

For a French Drain or a Surface Drain or any type of Drainage System, If in doubt, use a larger Drainpipe.  Four Inch Drainpipe is the most common. Six inch Drainpipe is always better.   If you are going to connect a French Drain and Surface Drain together, use 6-inch Drainpipe.

A NEW FRENCH DRAIN IN OKLAHOMA CITY

Recently we installed a large Drainage System in OKC.  It was a 4 inch System using 4 inch ADS French Drainpipe with Soc and 4 inch ADS Solid Drainpipe.  The “Intake” of the Drainage System had two parts.  Water from the gutters on the house was fed into the Drainage System.  There were 7 gutter downspouts around the entire house that were connected straight into the Drainage System with Solid Drainpipe and a Gutter connection.

A good place for a French Drain

We just finished a 4-inch Drainage System in Yukon.  It was a complicated system to install.  It utilized 4 inch French Drain in the flower beds, 12 inch Surface Drains on the side of the house,  6 inch French Drain along the garage foundation with 2 Pop – Up Emitters in the back yard and 3 Curb Fittings in the front.

First we installed 4 inch French Drain

in the flowerbeds on both sides of the front door.  We connected 4 inch solid Drainpipe into the French Drain and ran them underside walk to the curb.  Next we cut the curb with a concrete saw and installed 3 curb outlets for 3 separate French Drains.

Next, we installed 4 12 Inch Drain Basins with grates along both sides of the house continuing with Solid Drain Pipe to the Pop-Up Emitters on the back fence.

Finally, we completed the Drainage System by installing a long run of 6 inch French Drain down the side of the garage foundation.   Installing the French Drains in the flower beds was the most difficult and took the most time.

Each French Drain took over a ton of crushed limestone to fill the French Drain trench.  The Six-inch French Drain took even more limestone.

French Drains as part of a Drainage System 

Many times, people use the term ” French Drain” as general name for a Drain used in or around your home.  French Drains are designed to move a lot of water over a large flooded area.  They are also designed to take water in on the surface of the ground or below the surface of the ground.

This is very important if the water coming into the flooded area is moving through the ground or coming up from underneath.  ” Sub Surface Water Movement.”  The picture below is not a French Drain!

A French Drain looks like this

A French Drain Can Handle Standing Water

A French Drain can take in water in a broad area.  It can move a much larger volume of water compared to a Surface Drain.  Also, it can move sub surface water moving into the area where a Surface Drain won’t move any water at all.

Surface Drains are designed to move surface water only on a smaller scale in confined areas.

Each solves specific drainage problems.  A Drainage System may use one or both together or even several using many types of drains.

Do you have standing water in a large area in your yard? 

Typically this calls for a French Drain.  A French Drain is a great way to control standing water in a large grassy area.  It can also protect areas from flooding to a certain degree.  As long as the French Drains capacity to move water is not exceeded.  If the French Drains capacity is exceeded then water will stand in the drainage area until the rain stops and the drain has time to catch up.  A good way to prevent this is to install a bigger French Drain with a larger pipe.  The difference between a 3 inch French Drain and a 6 inch French Drain is huge.

Another way to beef up a French Drain is to connect gutter down spouts in front of the French Drain.  The water coming off the roof causes suction in the French Drain Behind it.  This greatly increases the French Drains ability to move water without increasing the size of the French Drain Pipe.

Double Six-Inch French Drain

We Installed a Double Six-inch French Drain in Edmond this week.  A Double Six Inch French Drain is two six inch French Drains laid side by side in one very wide and deep trench.

It is designed to move a huge amount of water away from a home.   Our customer had several different drainage problems in their back yard.  After a thunderstorm, water would run under their back fence and into their garage.  The back yard was on a steep hillside and the water would run very fast down the hill and into the garage.

Oklahoma Drainage and Sprinkler Repair installed 2 large six-inch French Drains across the water’s path.  This allowed the water to be diverted into the French Drain which then ran through drainpipe to a curb outlet at the street.

Three Gutter Down Spouts

were connected into the French Drain.  The French Drain created a protective barrier for the garage.

A 12-inch Surface Drain was also included in the Drainage System.  It was placed up against the driveway and connected with 4-inch Solid drainpipe to the 6-inch French Drain.

Water was completely rerouted away from the home.  A French Drain and Surface Drain combination in this case was the best solution to this particular drainage problem.

Oklahoma Drainage

installed a 4-inch French Drain in East Norman this week.  The customer had water standing on the side of his house that was causing foundation damage.  He contracted a Structural Engineer to come out and look at the Drainage Problem and to give him some advise.

The Structural Engineer recommended a French Drain to protect and draw water away from the foundation.  He said that, “he had recommended French Drain Installation to solve similar problems for home owners many times in the past.  The Structural Engineer was confident that it would solve the Drainage Problem.

FRENCH DRAIN IN EDMOND OKLAHOMA

Recently Oklahoma Drainage and Sprinkler Repair installed a large 6 inch French Drain in Edmond.  The customer had water running under his back porch step and into his basement.  We did a Free Drainage Diagnostic and Estimate.

The French Drain design

that we proposed would intercept the surface water and subsurface water that was flowing under the steps.  The French Drain design called for a 6 inch French Drain to be installed above and several feet away from the steps.  It would run around the house parallel to the foundation and about 5 feet to the East.

The French Drain would run past the steps to a point where water must cross the French Drain or run up hill to the steps which in this case was not possible.

Once past the steps, the French Drain would transition to Solid 6 inch Drainpipe and continue on around the house to the Pop-Up Emitter downhill in the side yard.  Along the way we attached several Gutter Down Spouts into the French Drain.

Hard rain

and flooding seem to be more common all the time.  When I started this business in 1993, having over an inch of rainfall in an hour was pretty extreme.  Now having over 4 inch an hour rainfall is not unheard of and is becoming more common.

Protecting our homes and businesses from unwanted water should be a goal for all of us.

Oklahoma Drainage has seen and dealt with virtually every possible Drainage and Standing water problem that can occur in or around your home.  With over 2000 Drainage Systems installed since 1993, we have amassed a great deal of experience.  This is help full in seeing underlying problems and secondary issues that may be hard to see at first for the ” Untrained Eye.”  This allows us to get things right the first time.

In this business EXPERIENCE TRULY COUNTS!

Hiring your brother-in-law to put in your Drainage System or French Drain is as bad as hiring a Lawn mowing company that does landscaping and drains too?  Water can cause a huge amount of damage.  How important is your money and your home?

Moving Foreword

The customer let us know that he was ready to move forward.  We scheduled the Drainage System Installation for the following week.  When the scheduled day arrived, we installed the Drainage System.  The Drain was made up of a 6-inch French Drain running 30 feet along the East side of the house.

It curved

around the corner of the house.  At that point a 12 inch Surface Drain was connected to the French Drain with 4-inch pipe.  The 6-inch French Drain at that point changed to 6-inch Solid Drainpipe and continued underground 65 feet to a pop-up emitter at the curb in the front yard near the street.

Edmond Oklahoma has been the location for many French Drain Installations for us in the past several years.  Recently we ripped out an old Surface Drain that was under a deck.  The Surface Drain was too small for the job and did not Protect the Foundation from Standing Water


 The First step

was to take out part of the deck along the wall.  Next we took out the Surface Drain and the Three Inch Pipe which was too small.  Digging a trench along the foundation came next.  We had to ensure the, “Fall” to make sure the water would run from left to right. 

 Next a French Drain Liner needed to be installed.  This was necessary to maintain the integrity of the trench and to keep the French Drainpipe from filling up with sand and getting clogged over the next few years.  Oklahoma Drainage then installed 4-inch ADS Perf/Soc French Drainpipe along the course of the French Drain.  

Next

we connected the end of the French Drainpipe to Solid 4 Inch ADS Drain pipe to continue along the trench to the Pop-Up Emitter at the Exit Point.

The French Drain we installed ran across the back yard in two places, then it connected to solid ADS Drainpipe and Ran to the street where a Curb Outlet was installed.

new curb outlet

Curb outlet for French Drain.

Installing a curb outlet takes experience and skill.  We cut the curb with a concrete saw.  Water is used with the saw to make better cuts and to keep the concrete dust to a minimum.  The cut in the curb will be at least two inches wider than the curb outlet that will be set in concrete.  This ensures strength and longevity.

When installing the cement,

we use cement with Acrylic to further ensure the strength of the outlet.  It takes a while for the concrete to cure.  The new concrete will be darker than the surrounding curb for a while but eventually it will match up.

We cut the sod out by hand when installing Solid Drainpipe.  The sod is set to the side while the 4 inch pipe is installed.  Then some of the dirt is placed back on top of the drain pipe and the sod is placed back in its original position.  Some of the dirt is left over that is displaced by the new drain pipe.  That dirt is hauled away. 

Recently

Oklahoma Drainage and Sprinkler Repair Installed a French Drain as part of a Drainage System in Mid West City Oklahoma.

Our customer had a back porch Sunroom.  Every time he had a hard rain, Water would run in one door and out the other.  An indoor creek across his Sunroom.

We installed

a French Drain in front of the South Door.  It was 26 feet long and ran from a gutter downspout which it was connected to, in front of the South Door and along the house covering the entire “Low” Area.  Then we connected 4-inch ADS Solid Drainpipe to the French Drain and ran down hill around the corner of the house to the street.

Once the 4 inch solid drainpipe was connected to the French Drain and the two gutter down spouts, a pop-up emitter was installed to release the water at the street.

The next step was to cover the drain pipe with dirt and put the sod back in place on top of the pipe.   There was about 8 wheelbarrows of dirt left over that was displaced by the drainpipe and the French Drain.  The extra dirt was scooped up and hauled away.

While installing the drainage system,

it was necessary to move two sprinkler heads that were in the way of the drain pipe installation.  This was no problem.  Installing drainage systems and French drains for folks who have a sprinkler system is very common.

Moving Sprinkler heads or pipes sometimes is necessary.  We always leave the sprinkler system in complete working order and we discuss any changes in the sprinkler system with the customer before we do it to make sure that everyone is on the same page.  In most cases the customer can’t tell that we made any changes to the sprinkler system at all.

 

French Drain Installation

can be a big part of installing a Drainage System.  A French Drain is not the only type of Drain that can be used.  A Drainage System can utilize several types of drains including a French Drain, Surface Drain, or Channel Drain.

Installing Gravel on top of a 6 inch French Drain

 

A French Drain is completely different from a Surface Drain.

A basic French Drain consists of a Perforated Drainpipe in the bottom of a trench.

A  Trench Liner is sometimes used depending on the Drainage System Design and the type of soil.

The Drainpipe should have a neoprene sock around the Perforated Drain Pipe.   This is to ensure that the Drainpipe does not become clogged.

A trench is dug that is slightly wider than the French Drainpipe that is being used.  There are several sizes of French Drainpipe.   Three Inch, Four Inch, and Six Inch are the most common sizes of French drainpipe.

The dirt that is taken out to make the trench is hauled away.  It is replaced by some type of small stone or gravel depending on what is desired or available.  I prefer crushed 1 inch lime stone.  It is the most economical option in my area.

Pea Gravel

or some other type of small stone can work just as well.    The lime-stone or gravel is placed in the trench on top of the perforated Drainpipe and filled all the way to the surface (ground level).

In some cases where the French Drain needs to be deep or is being placed in sandy soil, a special trench liner must be placed in the trench before the perforated Drainpipe or the Gravel are installed.  This helps maintain the integrity of the trench over time.  It also increases the cost of the French Drain and the amount of time to install it.  I install a trench liner in a French Drain Every time.

What a French Drain Can Handle

A French Drain is designed to handle a large volume of water and cover a large area. The Drain is anyplace the trench goes. It has many applications and can be used in many situations.  It can be installed by itself or incorporated into a Drainage System with Surface Drains or Gutter Down-Spouts connected to it.
The main downfall of a French Drain is that they, for the most part aren’t very pretty.  They don’t look very nice in a yard once they are completed.
Depending on the area the French Drain is installed and the type of grass around the French Drain, will dictate whether grass grows over the limestone.

Grass

can grow up and through the gravel in the French Drain over time eventually covering the gravel.  This is OK.  It won’t have a measurable effect on the performance of the French Drain.
In some cases, thick grass growing up through the French Drain will create a natural “Thatch” filter.  This makes the French Drain invisible.  The trick is to allow the grass to grow over the French Drain Gravel without covering it up with dirt.  Grasses such as Bermuda which grow well in the sun will put out runners and new roots and will grow up and through the French Drain.

Performance

This will not affect the performance of the French Drain.  The problem is that sometimes depending on the type of soil involved, it may take a long time to completely cover up the French Drain.  Sprinkling grass seed down in the gravel will speed up the process.

DON’T COVER THE GRAVEL IN THE FRENCH DRAIN WITH DIRT!

THE FRENCH DRAIN WON’T WORK IF THE TRENCH IS CLOGGED WITH DIRT.  DON’T EVEN INSTALL IT IF YOU ARE GOING TO COVER IT UP WITH DIRT.   
If you install a French Drain in a sunny area, you can:
                                         A.  Leave the French Drain as-is and allow grass to grow over it in time.
                                         B.  Add grass seed directly to the French Drain gravel with (Light Hand Watering) to speed the growth process
                                         C.  Leave the French Drain as-is but decorate it with steppingstones and landscaping rocks ( leaving large cracks between stones to allow water to get into the French Drain,

If you install a French Drain in a shady area you can:
                                        A.  Leave the French Drain as-is, it will work well and look as it did for many years.

                                        B.  Leave the French Drain as-is, but decorate it with steppingstones or landscaping rocks.  Many French Drains are hidden under rock walkways.

Sprinkler System Checkup Norman.

Lots of things can be done to make sure your Sprinkler System is ready to go.  All the Sprinkler Zones should be checked one by one.  The sprinkler heads and valves need to be checked to see if anything needs to be adjusted or replaced.

Sprinkler System Checkup is a Service Provided by Oklahoma Drainage since 1993.

Today we did a sprinkler repair in Norman.  The sprinkler system needed a checkup.

We went through each sprinkler zone and identified several different problems.

Zone 2 had a cracked sprinkler pipe in a flower bed.

A broken Rotor Sprinkler head was found immediately.

Next, zone five look good with no problems.

Zone 6 and 7 each had a couple of pop-up spray heads that were worn out and would not pop-up.  The diagnosis and the repair took less than two hours.  Now their sprinkler system is running great!

Now is a good time to have a Sprinkler System Checkup provided by Oklahoma Drainage.

Sprinkler Systems need to be checked before winter to prevent pipes from freezing.  Sprinkler Design determines whether sprinkler lines need to be bled.  Emergency shut off valves also need to be checked and turned off for the winter.

In the Spring,

all the water needs to be turned back on and all sprinkler zones and heads need to be tested.

Sprinkler System Check-Up process is very straightforward.  We run through all the Sprinkler Zones one-at-a- time from the controller. 

Sprinkler Controller

Sprinkler controllers can be a problem source.   Many times, the wires in the controller are loose or have a “Short” in one of the wires.  Sprinkler Programming can be a source of frustration.  We can help with Programming your controller.

We check all the sprinkler heads in that zone and the valves as well.

Once the Sprinkler System Checkup is Complete, we provide a Quote for what it will cost to make the needed repairs.

First Step

First, we dug up a good working area surrounding the broken Sprinkler Valves.  Next, we cut out the broken valves and crushed PVC pipes.  Finally, PVC pipe was cut and glued with new Sprinkler Valves following the original design and configuration.  In this case the three original sprinkler valves were connected to each other inside one Valve Box.

We aren’t done yet though; two sprinkler wires must be connected to each Valve.  One sprinkler wire is the “Common Ground.”  The other wire is the power wire.  All the sprinkler wiring is connected with water-proof wire connections.

The Common Ground

wire and the Individual Power Wires all come from the Sprinkler Controller.  Each Sprinkler Valve has its own power wire coming from the Controller.  All the Sprinkler Valves are Connected to the Same Common Ground Wire.

Before We Finish

Before dirt can be put back around the new valves, testing must be done.  Each valve must be turned on, “one-at-a-time,” at the Controller to ensure good wire connection and functionality.  Also, the Sprinkler Valves must be checked for leaks in the PVC Pipe.

Oklahoma Drainage and Sprinkler Repair provides Expert Service for Sprinkler Heads, Valves, Controllers and all other Sprinkler System difficulties.  We service Norman, Edmond, Oklahoma City, Moore, Yukon, Mustang, and Midwest City.

Sprinkler Controller Repair is a service provided by Oklahoma Drainage.  A Sprinkler Controller is the “Brain,” of a Sprinkler System.  They can wear out or stop working.  Power surges in the home can cause damage to a controller.

Programming can be difficult for homeowners.  We can help with programming or replace a Sprinkler Module if it is defective.

Start Time Programming

“Start Time” programing many times is confusing for homeowners.  The definition of a Start Time is a time that is chosen for the sprinkler system to start watering.  It causes zone 1 to start running.  When zone 1 is finished it automatically stops and zone 2 begins.  When Zone 2 is complete it stops and zone 3 begins.  Simple enough Right!  This continues until the last zone programed available runs.

The confusion begins when people think that a time needs to be set to start zone 2 and 3 and so on.  This is not the case.  They follow zone 1 which has the only Start Time programmed into the controller.

Be Careful with Multiple Start Times, just use One at first.

Sprinkler Controllers have a feature providing multiple start times, up to 4 Start Times are usually available.  These additional start times are only used when a person wants to run the entire system more than once in a 24-hour period.

For Example, the first Start Time is set at 9Am.  Zone 1 begins to run at 9am.  When Zone 1 is done, say 10 minutes later, Zone 2 begins and runs for 10 minutes, then zone 3 follows and so on.  By 10 am let’s say all the zones have run.  Let’s say 8 hours later you have a second start time at 6 Pm.  Zone 1 comes on and runs and by 7pm all the zones have run again.  So, the controller has 2 start times which have caused the Sprinkler System to run start to finish twice in a 24-hour period.

Here is the big problem!

Some Homeowners believe the second start time is to start zone 2 running.  They also think that the 3rd start time is to start zone 3 and the 4-start time is to run zone 4.  No!!

So, this is how they program the controller.  At 9am they have a start time and zone 1 starts.  The homeowner programs a second start time at 9:10 am to mistakenly start zone 2.  Nope!  It starts zone 1 all over again.  At 9:2o they have a 3rd start time for zone 3.  Nope!  It starts zone 1 for a third time.  Now the controller is stuck in a loop and zone 1 runs constantly and won’t shut off.

If Sprinkler Controller Programming is confusing?

Make sure you only have One Start Time!

“Run Time,” is completed Next.  It determines how long each zone runs.  Zone One 10 Minutes,     Zone Two, 15 Minutes, Zone Three 8 Minutes.  You can set how long you want each zone to run.
