Rule 500 GPH Standard 12V Bilge Pump Kit with Float Switch

The Rule 500 GPH Standard 12V Bilge Pump Kit with Float Switch includes a complete submersible bilge pump and a mercury-free automatic float switch. This is a pump-and-switch package, not a standalone switching accessory. The 500 GPH pump handles bilge-water removal, while the float switch turns the pump on when rising water reaches the switch.

The included pump has a stainless steel shaft, ignition protection, and high-abrasion, tin-coated silicone-blocked wiring. A backflow preventer helps limit water draining back into the bilge through the discharge hose. Its 500 GPH capacity suits a properly sized 12V bilge installation, and the separate included float switch provides automatic operation without mercury.

Mount the pump at a low point in the bilge and locate the switch where it can rise and fall freely. Verify fuse protection, wiring, hose routing, and electrical compatibility before fitting the components. Test the system with water after installation and inspect the intake and float switch during routine boat maintenance. Rule lists a three-year warranty for the kit.
