Rule

Wide range of Rule submersible bilge pumps and Rule bilge switches. With high flow rates and low battery drain, DC submersible pumps transfer water quietly and efficiently against low heads. Flow rate falls rapidly as the discharge head rises. Use the recommended hose size: undersized hose won't harm the pump,but you will get significantly less flow. These Rule bilge pumps are best suited for light, intermittent duties handling cleanish bilge water.
