Sump Pump

In Plain English

A pump in a basement pit that automatically pumps out groundwater before it can flood the basement.

Definition

A pump installed in a pit (sump) at the lowest point of a basement or crawlspace to collect and discharge groundwater that accumulates around the foundation. Submersible sump pumps sit in the pit while pedestal pumps have the motor above the pit. Battery backup systems maintain operation during power outages when flooding risk is highest.

Example

The addition of a battery backup sump pump gave the homeowner protection during storms that caused power outages.
