When it comes to installing a French drain system, there are many things to consider and a few mistakes people make when they’re first getting started. Let’s take a look at the 5 most common mistakes people make when they’re installing their French drain systems.
Mistake 1: Constructing Using Poor Materials
There are a lot of mistakes that can be made when constructing a french drain. One of the most common mistakes is not using the right materials.
This is one of the most common mistakes that people make when constructing a french drain. The type of material you use will determine how well it drains and what kind of problems it will cause if it leaks or seeps.
Mistake 2: Failure to Make Sure the Leach Lines Are Correctly Installed
A french drain is a drainage system that is installed under the slab to remove water from a basement. It is typically installed by digging a trench in the ground and then laying a pipe that runs along the bottom of the trench. The water enters the pipe, travels down it, and exits through holes in the pipe’s side.
An incorrectly installed french drain can cause serious problems in your home, such as leaking and flooding. This can lead to expensive repairs or even worse – damage to your property.
It’s important to know what you are doing when installing french drains because they can be tricky to install correctly and will require some knowledge of plumbing before taking on this project.

Mistake 3: Not Having Enough Compaction in the French Drain Line
A French drain line is a drainage system that is installed on the property. It is usually composed of a pipe that runs underground from the highest point of the property to a low point. This pipe collects rainwater and other water from the property and carries it away from it.
The French drain line has many benefits, but also has some drawbacks. One drawback is that there isn’t enough compaction in the drainage system, which means that when you have heavy rains, water may not be absorbed fast enough by the ground and will create flooding problems.
A French drain line should be installed with an adequate amount of compaction at all times so that water can be absorbed fast enough into the ground during heavy rains.
Mistake 4: Using Too Small of an Opening at the End of Each Leach Line
People make some common french drain mistakes when installing it. A french drain is a drainage system that’s placed under the ground to remove surface water and excess groundwater from your property.
The opening at the end of each leach line should be no smaller than 36 inches in diameter.
Mistake 5: Not Inspecting Your French Drain System Regularly for Failures or Defects
French drain systems are typically installed underground and have a round shape. They are designed to collect water from the ground and direct it into a gutter system, which is then pumped out of the property.
It is important to inspect your french drain system regularly for any defects or failures. If you find any, you should contact a plumber as soon as possible.
How can homeowners avoid these mistakes?
French drains are a common feature in backyards and are usually installed by homeowners. However, they can be very costly to install if done incorrectly or not at all.
A lot of homeowners make mistakes when installing their french drains. Here are the most common mistakes that people make when installing these drainage systems:
– Not digging deep enough – This is a big mistake that most people make. French drains need to be dug at least 3 feet deep and placed in a trench with a slope of 1/2 inch per foot.
– Not placing the drain in the right location – If you don’t place your french drain where it’s needed, you’ll end up with flooding problems and water damage.
– Using gravel instead of sand – This is another big mistake that people make because gravel doesn’t retain water and can be very harmful in your garden. It can create a mess for you when it erodes, or wet any plants nearby and harm them.
