The eco-friendly Rule Mate series of Bilge pumps feature a solid state water-sensing technology that eliminates the need for a separate float switch. - When water enters the bilge and reaches a certain height (2-3/4 inches) a sensor turns the pump on. After the water is pumped out, another sensor shuts the pump off. - The sensor's unique field effect technology is programmed to recognize the dielectric constant of water only. In the event of an onboard oil spill, straight engine oil that enters the bilge will not turn the pump on. It's part of Rule's continuing commitment to preserving our waterways.
