Smart, Automatic Operation

The Rule-Mate RM800B is a fully automatic bilge pump that combines a water sensor and pump in one compact unit. When water reaches a certain level, the sensor activates the pump. Once the water is cleared, it shuts off automatically. No separate float switch is required, simplifying your bilge system.

Advanced “Spongeability” Technology

This unique feature ensures the bilge is left drier than ever, minimizing unpleasant smells, cutting excess weight, and helping improve fuel efficiency. A drier bilge means a cleaner, lighter, and more efficient boat.

Easy Testing with Pump Check Button

Need to verify the pump is working? Simply press and hold the built-in pump check button to activate a quick test cycle. Great for regular checks before heading out on the water.

Built for Easy Setup

The pump includes a threaded discharge port with an O-ring seal and comes supplied with both straight and 90-degree 19mm (3/4") hose fittings, offering flexibility for various plumbing setups. The internal wiring design also simplifies installation.

Safe and Durable Design

With thermal overload protection, an anti-fouling impeller, and a removable strainer for clearing debris, this bilge pump is engineered to last. It's ignition protected and safe for marine use, drawing just 3 amps at full output.
