Bilge pumps are designed to remove water that reaches the bilge. Non-automatic pumps require a device to control the pump, engaging the pump when water enters the bilge, and then disengaging the pump when water has been removed. Xylem’s Rule brand offers a portfolio of bilge pump float switches that are designed to suit all boat requirements and pumps from 360 GPH, up to 4000 GPH.
