Basics of Operation
-
A sump pump, located in a sump pit set in the floor or ground, gathers unwanted water as it enters the home. The pit accumulates the water until it reaches a predetermined depth, when the pump automatically activates and pumps the water from the home via a drain line. It is generally against city codes to plumb a sump pump drain line into the house's normal drainage.
Pedestal Pumps
-
Perhaps the most common type of sump pump, a pedestal sump pump consists of a motor mounted atop a pedestal or pipe. The motor drives the pump impeller, located at the pedestal base. The pump generally requires an open sump pit in which to operate. The motor, not designed to encounter water, is activated by a float attached usually to the side of the pedestal.

Submersible Pumps
-
A submersible sump pump is a compact unit that sits in the base of the sump pit and can be fully submerged in water without damaging the motor or any of the components. The unit is activated when the water reaches a preset depth. A submersible pump can be used in a fully enclosed sump pit. Submersible systems are quiet and offer an added level of protection from mold or mildew.
