Rule 500 GPH AUTO PUMP 12V

Sensing bilge pumps 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. Water is kept in check between 1/8 and 3/8. Great idea when power conservation is needed and as an added benefit, no float switch is needed! Completely automatic with manual override
