Rule-Mate fully automatic submersible bilge pumps with Rule’s exclusive “Spongeability” feature. New innovative design incorporates the bilge pump and water sensor in a single housing. Unique Rule “Spongeability” feature leaves the bilge the driest ever – when water in the bilge reaches a certain height the sensor automatically activates and the pump runs until water is pumped out, reducing boat weight, saving fuel and minimizing bilge odour. Pump check feature – simply touch the pump check button and hold for a few seconds to test cycle the pump. 3 year limited warranty.
