Seepage, mold, wood rot,moss growth, insect activity, andlong-term damagecan occur.
Move the water as far away from the foundation as possible.
The pipe should have a 0.25:10 decline or greater (1/4-inch per every 8 to 10 feet).

If there is no slope, create a trench running on a decline.
Dig the Trench
Stake out the area to be trenched with the string and stakes.
Toss the soil on a plastic sheet to avoid adding dirt and mud to the lawn.

Store Dirt Under Plastic Sheeting
Mound up the dirt from the trench under plastic sheeting.
Close up the sheet at the end of every workday.
Extend the pipe as far as you need.

Also, have a gravel bed along the first foot or two along the drain pipe.
Gently twist the 4-inch pipe into the side of the catch basin and through the flexible sleeve.
The end of the pipe sits in the grooved ring and is sealed with silicone caulk.

Tip
ensure that the drain gravel is high enough to support the pipe.
Avoid having the catch basin’s sleeve support the pipe.
see to it that the pipe extends about 3 or 4 inches.
Lee Wallender
Do not have the pipe enter the basin flush with the side of the basin.
Catch basins and pipes should be fitted tightly to be leak-free.
However, some leakage is expected.
Lee Wallender
This is not a pressurized system where no leakage is required.
ThePVC pipesdo not need to be cemented.
Drill several weep holes at the bottom of the basin to prevent water from pooling.

Insert the pop-up emitter and its self-closing cap.
A simple barrier can be built from one-by-eight pressure-treated lumber to roughly 18 inches square.
Cut a half-circle into one side (at the bottom) so the barrier can rest on the pipe.
Lee Wallender
Always keep the cap clear because frequent cleaning of the elbow joint is necessary.
Backfill the trench and around the catch basin with gravel, sand, or dirt.
The more gravel you’re free to use, the better.

Gravel helps water drain away faster.
Professionals have trenching tools that speed up the process and eliminate much of the hard labor.
For example, a catch basin makes sense at the end of a water downspout.

It catches the water from a fixed point.
In contrast, a French drain can handle runoff water flowing across a wider area.
French Drains
AFrench drainis made by digging a long trench and laying perforated pipe along the trench.
Lee Wallender
Heavy rain can overwhelm a French drain system, causing pooling.
Both do the same thing by collecting the flow of excess water from rainfall.
Dry Wells
A dry well is a large receptacle for unwanted water runoff.
Water is collected in the well, either led there from a pipe or seepage from above.
A catch basin collects excess water and reroutes it away from your house.
Often, it goes to local waterways.
