Basic French Drain Installation
consists of a Perforated Drainpipe in the bottom of a trench. The French Drain Trench runs through a Problem Drainage Area that needs to be drained. The French Drainpipe is perforated (Full of Small Holes) and has Neo-Prene Soc around the pipe. This soc helps prevent debris from clogging the French Drainpipe.

Installing a French Drain in the mud
Standing water
can cause a lot of damage to your yard. The above picture was from a French Drain Installation in Oklahoma City.
Many times, we wait until things dry out a bit before beginning a French Drain Installation. Sometimes the water never goes away. So, we start digging in standing water and putting the mud in a wheelbarrow. We then haul it to a dump trailer to be hauled away. It isn’t the easiest thing to do.

Perforated Pipe, Filter, and Liner installed in a drainage trench.
The Initial Dig
The water started draining away as soon as we dug the Drainage Trench. Once the Pipe and Limestone were installed, it drained away even faster.
The trench liner allows sub surface water to pass through it and reach the French Drainpipe. The reason it is installed is to maintain the integrity of the drainage trench, so it doesn’t collapse over time. It also helps protect the pipe from filling up with mud or sand, clogging the French Drain.
Below is a picture of a French Drain that we had to take out and replace because it had no liner or filter around the Pipe.
The French Drainpipe shown above has a neo Preen soc around it to prevent sand and debris from clogging the French Drain. The next step is to add the limestone on top.
Other types of stone can be used as well.

A French Drain with River Rock
The type of rock
that covers a perforated French Drainpipe can be just about any type of quality gravel or crushed stone. Very small, crushed stone or sand is not a good idea, however. The water must be able to flow through the stone to reach the perforated pipe.

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 Stormwater 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.

- Surface Drain and Drainpipe
A Channel Drain is a type of Surface Drain, and many times is installed in concrete across sidewalks or driveways.
French Drain or Surface 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. 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.
Crushed 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. I install a trench liner in a French Drain Every time.

DECORATIVE STONE CAN BE USED TO COVER A FRENCH DRAIN AND THEY LOOK GREAT AND LAST A LIFETIME.

Back-Flow-Valves
There are two types of Back-Flow-Valves.
Above Ground
Below Ground Back-Flow-Valve.
What is a Back-Flow-Valve?
A Back-Flow-Valve is a part of a Lawn Sprinkler System. Water passes through it from the water source which can be a Water Meter or a Well Pump. It forces water to travel in only one direction from the source to the sprinkler system. It can’t travel backward back to the water source which again is a water meter or well pump.
A Back-Flow-Valve provides protection to the water source from back pressure and chemical contamination from lawn fertilizer.
Most Cities require a Back-Flow-Valve as “Code” for Sprinkler Installation.
Emergency Shut off
Back-Flow-Valves usually have an Emergency Shutoff valve on them that can shut off the water to the lawn sprinkler system but keep the water turned on to the home. Most Back-Flow-Valves have two Emergency Shut off Handles. Either one will work. Many times, they are hard to turn, however.
If there is a leak or water is shooting up in the air just turn the valve handle and give us a call.

Norman Sprinkler Checkup is a Central Focus for Oklahoma Drainage. We Performed or first Sprinkler Repair in Norman in 1993. It was in Brookhaven on the West side of Norman.
Recently we had a customer in Oklahoma City who wanted to move his Sprinkler Valves. They were in a bad place in his flower bed. He wanted to plant a tree where the valves were located.
We moved 4 Sprinkler Valves about feet out into the yard. All the Sprinkler Pipes had to be redesigned and installed matching the new location and maintaining full functionality.

Recently we spent an afternoon checking out a Sprinkler System in Northwest Oklahoma City. The customer told us that many of the heads in the System had a variety of problems. Her Sprinkler System was fairly large so the Sprinkler System Checkup would take some time.
Sprinkler System Checkup
First, we had to run each Sprinkler Zone and look at each Sprinkler Head individually. This took a while. After that we fixed everything without a “Hitch.”
