Rulemate Auto Bilge Pump 500GPH

Rule-Mate 12V Fully Automatic Bilge Pumps feature a solid state water sensing technology that senses the dielectric constant of water. The pump will activate when the water level rises to 2-3/4" and will not turn on in the event oil enters the bilge. These submersible pumps are ignition protected and feature an anti-fouling impeller, black flow preventer and a snap-off strainer.
