Diagnosing the Problem

Start by identifying the issues causing your drainage problems.
In this application, we will be replacing old downspout adaptors as well as an existing french drain.
FLEX-Drain is perfect for tight places and curvy spaces.

Preparation

Measure the job site and downspouts and buy supplies accordingly.
Have Utilities marked before you dig and apply for any necessary permits.
Assess the ground slope and plan for where you will lead the water.
Be prepared with gravel (depending on application), top soil and grass seed as part of your supply list.

Digging

Renting a trencher makes quick work of digging and it doesn't cost a lot of money.
Measure trenches from 4-12 inches deep based on your project specifications.
For normal installation in mild climates, 8 inches is the standard.

Basic Installation

Installing FLEX-Drain is the easiest part of your project.
Connecting downspout adaptors to downspouts is easy.
Expand your pipe to fit and run the pipe in your trenches.
Install the Flexible T Y by snapping on the coupler first. Coupler TIP: Always attach to the cut piece first.

French Drain Installation

The idea behind French Drains is to rid your yard of low-lying water by allowing it to seep into the ground via perforated pipe and a barrier of gravel.
When it's time to connect the perforated pipe with sock to other pipes, cut the sock to connect to other pipe.
Block the end of the French Drain by tying the extra sock in a knot.

Tight Places, Curvy Spaces

The ability to use FLEX-Drain in tight places or around curvy spaces makes this job simple..
FLEX-Drain can be installed around retaining wall, existing plants and trees or anything else that you don't want to dig up.

Finishing

Install an end-cap to run the water out to the street, or into a gutter, for a nice clean finish.
Backfill the pipe with gravel where the perforated pipe has been used.
For basic installations, backfilling with top soil is sufficient.
Put some grass seed over your finished project and your yard will be good as new!
