Sump Pumps

Sump pumps are used where basement flooding happens regularly and to solve dampness where the water table is above the foundation of a home. Sump pumps send water away from a house to any place where it is no longer problematic, such as a dry well. Usually hardwired into a home’s electrical system, sump pumps may have a backup. Since a sump basin may overflow if not constantly pumped, a backup system is important for cases when the main power is out for prolonged periods of time, as during a severe storm.

There are generally two types of sump pumps — pedestal and submersible. The pedestal pump’s motor is mounted above the sump, where it is more easily serviced, but is also more conspicuous. The pump impeller is driven by a long, vertical extension shaft and the impeller is in a scroll housing in the base of the pump. The submersible pump is entirely mounted inside the sump, and is specially sealed to prevent electrical short circuits.

Sump pumps generally don’t need maintenance, however, they should be checked regularly to ensure the motor is still good and the pump is working properly.
