French Drain Installation
French Drain Installation was the first job we ever completed back in 1993.
It all began for Oklahoma Drainage in 1993. We installed our first French Drain South of HW 9 near the golf course.
Business Started Slowly. There was no website or other forms of Advertisement. Just Paper signs staked on the side of the road.
Since then, we have helped over 5000 customers in central and Western Oklahoma.

French Drain in Norman
Recently Oklahoma Drainage installed a 6-inch French Drain for a customer in East Norman. She had water coming down the hill in her back yard, on to her patio, and into her back door. Also there was water standing on the side of her house. Water was standing near the AC unit. Water was standing by the South side garage door too.
We installed a 6 inch French Drain all the way around the house with 2 curb outlets, One on the North Side of the driveway, and one on the South.
We also connected 4 Gutter Down Spouts directly into the French Drain which made the Drainage System more efficient and caused suction in the French drain improving performance and preventing Vapor Lock during Flooding Situations.
This Design Solved all their water problems and was tested with a heavy rain the day after work was completed.
What Size French Drainpipe is Available
When installing a Drainage System of any type, a decision must be made on the size of Drain Pipe used. Typically, 6-inch, 4 inch, and 3 inches are the most common in Residential Drainage Systems.
If you have one or two 6-inch Surface Drains or a stretch of French Drain that is less than 10 feet, then a 3 inch drain pipe can be used. Three-inch drainpipe is used for low volume applications.

4 inch and 6-inch Drain Pipe
If you have two or three 12 inch Surface Drains or a stretch of French Drain that is 60 feet or less, then 4-inch drainpipe should do the job.

12 Inch Surface Drain Installation
If you have Six 12-inch Surface Drains or less or 100 Feet of French Drain, Then the use of 6 inch drain pipe becomes necessary.

100 feet of French drain
Drainage Limitations
These numbers can be exceeded. More Surface Drains or French Drain can be added to the above listing. As a result, the drainpipe will be overwhelmed at times of heavy rain. If it is OK with you for your French Drains or Surface Drains to Stand Underwater for a while. In most cases the Drainage System can catch up and clear the excess water away. How long it stays underwater varies from one application to another.
Slope is a big consideration. If your drainpipe runs downhill nicely and the water moves quickly, then you can exceed the above numbers. If you have very little slope and your Drainpipe only runs downhill slightly, then installing fewer drains is definitely a good idea.
Connecting a gutter downspout to a drain that only has a small slope is always a good idea. The water on the roof has nice velocity when it comes out the gutter and into the drainpipe. It speeds up the water movement when the slope ins’t very good. It also causes suction behind the gutter downspout in the French Drain or Surface Drain that you have installed.

One Common problem is that they continue to run and won’t shut off. In most cases this is a problem with a sprinkler valve that has “Stuck” in the on position.
This can be temporarily solved by shutting of the Emergency Shutoff Valve. The problem is that some sprinkler systems don’t have one to turn off or if they do the homeowner doesn’t know where it is.
It may be on the back-flow valve which may be located on the side of the house under a big plastic fake rock.
Many sprinkler systems in Oklahoma have them. (50 % ?) Under the plastic rock is a back-flow valve with two shut off handles. Usually, they have blue or green or tan handles. Turn one of the handles and it should shut off the water to your sprinkler system.
Other times the Emergency Shutoff Valve is in a box in the ground out by the curb near your water meter. The valve box will have a green lid. Sometimes they are difficult to open. Many times, I had to pry them open with a flat head screwdriver.
Inside the valve box is a plastic handle that can turn off the water to the sprinkler system. It can be blue or red or grey in color.
Many times, the valve box will be full of dirt, and you can’t turn or even see the handle until some of the dirt has been dug out by hand.
Water might be shooting up in the air somewhere on your property. This can be caused by a broken sprinkler pipe or sprinkler valve.
