How To Install A Channel Drain In
A French drain may be the solution if youre experiencing water drainage problems. A French drain is a type of trench drain used to divert water away from a specific area. French drains are typically installed in front of garages and other areas where water drainage is problematic. They are made up of a sloped concrete or metal grate that channels water towards a drainage system or storm sewer.
The French drain in front of your garage door helps keep the water from pooling near your home and damaging your foundation or concrete slab. How does a French drain work? The water pools near your home are caused by rain and melting snow. The water runs off of your roof and driveway and collects near your home.

Can You Install A Garage Floor Drain Yourself
Yes. Theyre really no that hard to install. Its important to have a plan before you start working.
Figure out the location of your drain first. This is point A. Then determine where youll be draining all the water too. This is point B. Finally measure and plan out how youll run the PVC to get point A to connect to point B.
Remember that drains and pipes need to run down hill to work. If the floor drain pipe is 8 inches deep, then the outlet, point B, needs to be at least 13 -14 inches deep. I like to pitch about an eighth to a quarter inch per foot of PVC pipe running down hill.
You can do the demolition if its needed, dig the trench, install the drain pipe, and install the bell trap or trench drain all on your own. It involves a lot of time and labor, but its actually not that hard to do. Once the planning is out of the way and you figure out all your heights its just digging and running PVC.
There are two important things to remember when installing a floor drain on your own.

LENGTH: The total length of the channel should be around the same as the garage door width. It could be shorter or longer than the driveway width, but not by too much. Channel sections come in standard lengths of around 39 . Several sections can be snapped together to give the required length.
WIDTH: Channels come in standard widths. The channel width can range from 1 to 12. The size that is best for you will depend on the maximum amount of water flow that you are expecting.
DEPTH: The depth of the channel is related to the width and the maximum amount of water flow that you are expecting.

How To Install A Channel Drain Free Workout Included
Youll want to choose a site for the drain at least a foot or so from the area youre trying to protect. The idea is to intercept the water before it runs into your wall, garage door, or whatever. Once you have the site picked out, map out a route to carry away the water youll be collecting. Make sure youre not solving one problem, but creating another. If theres a street or ditch close by, and local ordinances dont prohibit it, theres your ideal destination. . In our case, to get it to the street would have required an uphill run of pipe, so gravity dictated that we route it around the side of the shed and onto the hillside behind it. There it continues to flow down the hill to an area of trees and random assorted greenery. Any leftover water continues into the alley, and ends up in the storm sewer, and shortly after that in the mighty Ohio River a much more suitable destination than my shed.
Make sure your pipes are sloping away from the drain. A steep angle isnt necessary, but try not to end up with any troughs in the pipe, where water can collect. If you end up with too much water in the pipe, its possible it will freeze, expand, and crack your lovely pipe next winter. Of course, this assumes you live in a frozen wasteland, like I do if you live in a tropical paradise, like San Diego, its not quite so critical.

Cleaning Out A Clogged Trench Drain
Pull off the cover, remove debris. At one or two locations you will find a hole in the bottom, turn on your garden hose, and stuff it in the hole. Keep stuffing it down the hole until the water runs freely down the pipe.
fstime said:Ok well, the drain leads to a 2×2 storm drain 5-6 feet in front of the trench drainI put a garden hose in the trench drains outlet pipe and the water gushed out inside the storm drain no problem so the connecting pipe does not seem to be clogged.There was water entering the house again. Sticking a long metal rod into the storm drain indicated there was about 1 foot of sand that could be cleaned out at the deepest part and about 4-5 inches elsewhere. It is about 4 feet deep overall and around 3×3 inside and lined all around with cement blocks. So I don’t get it, I don’t think removing some building at the bottom is the core issue here. Granted every time it has failed, flash floods were declared and rain was dropping at 1-2 inches per hour, not some little sprinkle but for it to occur 3 times in 3 months means something is giving.
It looks to me that there is a curve there and I could see how that could help but the driveway is fairly short and steep leaving not much room for implementing such a thingI was referring to something like this
fstime said:My city does not allow tying in storm drains with the sewer system.You are correct though that the “well” has a limited capacity other than draining into the ground naturally.
Solve Your Driveway Water Problems
Do you get water in your garage from the driveway? Does water pool near the garage door, and come in? If the driveway slopes toward the garage doors, and the surrounding area is higher than the driveway. The water stays in the area of the doors. The water has no place to go. It pools or comes into the garage. That can damage the foundation, walls or things stored in the garage. It can also erode areas at the surface as well as underground.
The best and easiest solution would be to put drains off to the side of the driveway. That way you do not have to cut into the driveway. .
More than likely the solution will require the driveway to be cut. Install a catch basin if the water is in one low spot. If its in more than one spot, choose the lowest area and install a trench drain across the entire driveway or a portion, if you can get away with that. Then pipe the water underground to a lower area.
Warning about underground utilities! Any time you dig, it is your responsibility to know what is located underground where you are working. BEFORE YOU DIG! Check with the local authorities in your area for assistance.
