1100GPH Electronic Sensing Bilge Pump - 12V

In the next generation sensing bilge pumps the 1100GPH 12V S series pump works on the principle of impeller resistance. The pump will turn on every 2-1/2 minutes for about one second to sense for water. If water is present the pump will sense resistance and continue to run until all water is removed. After that it will resume checking for water every 2-1/2 minutes. Features -1100GPH Electronic Sensing Bilge Pump - 12V -Water is kept in check between 1/8in. and 3/8in.
