Rule Mate 500GPH Automatic Bilge Pump 12V Sensor No Float Switch

The Rule Mate RM500B is a fully automatic 500 GPH bilge pump designed for reliable and eco-friendly operation. Its solid-state water sensor eliminates the need for a separate float switch, and the pump will not activate in the presence of straight motor oil.

The pump automatically turns on when water reaches about 2-1/2" and shuts off at 5/8". Built-in programming protects the pump and your vessel by sensing when the pump is running dry.
