What is a sump pump?

A sump pump sits in a pit, or basin, dug into the lowest point of a basement floor. This pit collects water that seeps through foundation walls or rises from the water table. When water reaches a certain level in the basin, the pump's float switch activates, and a motor-driven impeller forces the collected water up through a discharge pipe and away from the foundation, typically to a storm drain, dry well, or daylight outlet.

The two main types are pedestal pumps and submersible pumps. Pedestal pumps mount on the basin's rim with the motor above floor level, making them easier to service but more visible in the space. Submersible pumps sit inside the basin beneath the water line, taking up less floor space and running more quietly, though they are harder to access for maintenance.

Sump pumps are essential in Trumbull County basements where clay soil and seasonal groundwater create persistent moisture problems. Without one, standing water can damage foundations, promote mold growth, and destroy stored items. Many basement waterproofing companies install sump pumps as part of a complete water management system, often pairing them with interior or exterior drainage and sealing work to keep basements dry year-round.
