Product Description

Rule-Mate Automatic 500 GPH Bilge Pump 12v

‘Rule-Mate’ fully automatic submersible bile pumps with Rule’s exclusive spongeability feature.

All in one bilge pump and switch – no need for independent float switch.

The innovative design incorporates the bilge pump and water sensor in one single housing – save space!

Rule’s unique spongeability feature leaves the bilge drier then ever. When water in the bilge reached a certain height the solid state sensor automatically activates and the pump runs until the water is pumped out, reducing boat weight, saving fuel and minimizing bilge odour.

Pump check feature – simply touch the pump check button on the pump, hold for a few seconds to test cycle the pump.

Pump has a threaded discharge port with O ring seal and are supplied with both 90 degree and straight hose port – 20mm.
