Automatic Operation: 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.(On 2-3/4"; Off 1/2")
The sensor's unique "field effect" technology will only recognize water. If a 100% concentration of oil is detected the pump will not activate. This is not a zero discharge prevention system. The result is the most technically advanced bilge pump available in the marketplace.
