Fully Automated Bilge Pumps Powerful bilge pump and a new non-mercury float switch in a single housing. While fully automated, the pump will only turn on when the water level rises. There is no cycling and battery drain. The pump remains off until the internal float switch rises. The pump then stays on until the water is evacuated. The pumps's internal computer senses no load (water) against the impeller and then shuts off. A detachable strainer provides easy access to the impeller area for removal of debris. Each pump is easily installed with the pump and switch internally wired. A third wire allows the pump to be connected to a manual override switch if so desired.
