The new Rule-Mate™ series of Fully Automated Bilge Pump feature a pump and a non-mercury float switch in a single, compact housing. As the water level rises, so does the float switch, activating the pump when the water level reaches 2 1/8". There is no on/off cycling and therefore, no power use until the pump comes on. The pump remains on until the float drops and the pump senses no load against the impeller. 12V.
