Rule-Mate Automatic Bilge Pump 500GPH 12V

Keep your vessel dry and protected with this dependable automatic bilge pump. Using smart solid-state sensing, it springs into action when water rises and powers down once the bilge clears—no float switch required.

The anti-fouling impeller and quick-release strainer make maintenance straightforward, while minimal power draw until needed means your battery stays healthier longer.

Built-in intelligence guards against common problems like blockages and air-locks. If the pump runs dry, it automatically shifts to a low-power monitoring cycle, checking every 2.5 minutes until normal conditions return. It activates around 63.5mm of water and shuts off at 16mm, giving you reliable, hands-free protection in any conditions.
