Rule-Mate Fully Automated Bilge Pump 2000GPH 12V is engineered to keep your vessel dry with smart, hands-off reliability. This compact, all‑in‑one unit combines a robust Rule bilge pump with an intelligent control board inside a single rugged housing, built to handle the toughest marine conditions.

Automatic, sensor‑driven water removal

When water rises to 2-1/2 inches, the pump automatically activates, delivering up to 2000 GPH (7570 LPH) at 0' head. As the water recedes to roughly 5/8 inch, the system shuts off automatically, leaving your bilge dry and ready for the next wave. The continuous on/off behavior is designed to minimize energy use and protect your battery bank.

Smart protection you can trust

Unique to Rule-Mate, the built-in programming monitors pump operation and detects when it is running but not moving water. If debris fouls the sensor or the impeller becomes air-bound, the pump stops and enters a check cycle every 2-1/2 minutes. Once the obstruction is cleared, it returns to normal operation. This protection helps prevent burnt-out motors and battery drain while extending pump life.

All‑in‑one design, versatile connections

The 1 inch NPS discharge is compatible with standard hoses, and the pump ships with both a 1 inch and a 1 1/8 inch screw-on port, making it easy to adapt to most bilge configurations. With an extra-long life heavy‑duty motor, it’s built to endure long seasons of use with minimal maintenance.
