Rule RM500B24 Rule-Mate™ Automatic Bilge Pump, 500 GPH, 24V

The eco-friendly Rule Mate pumps feature a solid state water sensing technology to eliminate a separate float switch. The sensor's unique "field effect" technology is eco-friendly because straight motor oil in the bilge will not turn on the pump. Includes a straight hose fitting, a snap-on strainer for easy cleaning and an anti-fouling impeller. 3-Year limited warranty.
