A submersible sump pump is a machine that is used to remove water from a special pit used to collect water. The pit is called a sump. There are two primary types of sump pumps: a pedestal sump pump and a submersible sump pump. Both types of pumps are generally used to pump water away from a home and keep a basement from flooding during a heavy rain storm. This article will explain how the submersible type works.
Submersible Pumps Work Underwater
Unlike pedestal pumps, submersible sump pumps are designed to be placed directly in the sump pit and can operate even when covered with water. The pump uses a motor that is totally enclosed in a waterproof casing that allows the pump to work in this manner. This design is preferred by homeowners that want a quieter type of sump pump.
How They Work
A submersible sump pump has a special sensor that can detect when water reaches a certain level within the sump pit. Once the sensor activates the pump motor, the device uses an impeller (special rotor blade for increasing the flow of liquid) to force water out of the sump pit through a hose or pipe that is used to direct water a safe distance away from the home and basement.
