Choose a Sump Basin Location and Prepare the Crawl Space

Access your crawl space, and remove debris, old lumber, and trash. Survey the area to determine the best location for the sump basin. Choose the lowest point where water tends to accumulate. This ensures efficient water drainage.

Plan Drain Tile Layout

While not mandatory, using drain tiles can accelerate water drainage. Plan the layout, considering areas you want draining. Create trenches for the drain tile, sloping them toward the sump basin. Ensure proper water movement into the basin.

Dig a Sump Basin Hole and Trench for Drain Tile

At the chosen location, dig a hole for the sump basin and trenches for the drain tile if you’re using it. Allow enough space for rock aggregate around the basin and tile. Be cautious around foundation walls, maintaining a safe distance.

Prepare the Sump Basin for Use

Check if the sump basin needs any modifications. If using drain tile, ensure there are access holes for pipes. Drill holes if necessary. If your access is limited, consider cutting the basin into halves for easier installation and reassembly.

Install the Sump Basin and Drain Tile

Place a layer of drainage aggregate at the bottom of the sump hole. Set the sump basin on the aggregate and connect the drain tile pipes. Cover the drain tile with an aluminum screen or use fabric-covered tile to prevent aggregate from entering.

Prepare and Install the Sump Pump

Attach the first part of the discharge PVC pipe to the sump pump. Ensure proper fittings and consider drilling a small hole in the pipe for drainage. Place the sump pump in the basin, cleaning out any debris. The pump activates when the water level triggers the float switch.

Attach the Sump Cover and Connect the Discharge Plumbing

Pass the discharge pipe through the sump basin cover. Connect it to a combination union and check valve to prevent backflow. Plumb the remaining discharge circuit. This system ensures efficient water discharge after the pump cycle.

Addressing Common Concerns

What to do with the ends?

Do I need to put river gravel in the trench and then put the pipe and fill it again with gravel?

Do I need to perforate the basin from the bottom?

If using drain tile, perforate the basin to allow water entry. Otherwise, ensure the basin has appropriate access for efficient water drainage.
