What is the sump pump crock

The sump pump crock is where the water that is collected around the foundation by the drain tile goes. The typical size is 30″ deep and 24″ in diameter which can hold approximately 25 gallons of water. The crock should be located at the lowest point of the basement at least 8 inches below the basement floor line. When the crock is installed here are the acceptable items you should see inside:

Sump Pump
Float that activates the pump
Sump pump check valve
PVC discharge line
Openings for 4-inch drain tiles
Quater inch weep holes at the bottom

What you should NOT see inside the crock:

Mud
Debris
Leaves

During a rainstorm when the water level in the crock 4 to 5 inches the sump pump activates. Once the sump pump is activated it will discharge the water outside the home and away from the foundation. It is important to inspect the crock every couple of months to ensure that you don’t see things on the NOT list above. If you see things on the NOT list it indicates that you have a potential issue with the pressure relief system.
