Rule-Mate 500 GPH Fully Automated 24V Bilge Pump

The Rule-Mate 500 GPH Fully Automated 24V Bilge Pump combines a submersible bilge pump and automatic water sensing in one compact housing. Integrated electronics start the pump as bilge water rises and stop it after the water has been removed, eliminating the need to install and wire a separate float switch.

The Rule-Mate design includes an anti-fouling impeller and backflow protection to support dependable automatic operation in a marine bilge. Keeping the pump and sensing system together simplifies installation and reduces the number of separate components competing for space in smaller or crowded bilge compartments.

Confirm electrical supply, fuse or breaker protection, discharge-hose routing, mounting location, and service clearance before installation. Keep the sensing and intake areas clean, secure the wiring carefully, and test automatic start and stop behavior with water present.
