RWB Rule-Mate 500GPH Automatic Bilge Pump - 12V

PHONE ORDERS (07) 4357 8991

Rule-Mate fully automatic submersible bilge pump with Rule's "Spongeability" feature. Innovative design incorporates the bilge pump and float switch in a single housing. Unique Rule "Spongeability" feature leaves the bilge the driest ever.

When the float switch drops and the pump senses no load against the impeller, the shut off phase begins. At that point the pump will run an additional 15 seconds allowing the pump to take the bilge water level down by an additional 10mm, reducing boat weight, saving fuel and minimising bilge odour.
