Mate Fully Automated Bilge Pumps Mate 2000 Gph Auto Bilge Pump The new Rule Mate series of Fully Automated Bilge Pumps 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 18. There is no onoff 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.
