Keep your bilge dry

Clearing water from the bilge is one of the most important jobs on a boat, and Rule is the trusted standard in bilge pumps. The line covers submersible bilge pumps in a range of capacities, automatic pumps and float switches that turn the pump on when water rises, and aerator pumps for livewells. Reliable and widely used, Rule pumps keep the bilge dry and clear incoming water from rain, spray, or a leak, protecting your boat. For boaters outfitting a new boat, replacing a failed pump, or adding a backup, Rule offers dependable bilge pumps and the switches to automate them.

Choosing the right pump comes down to capacity and operation. Size the bilge pump to your hull and the water it must clear, choosing a capacity with margin, and consider a larger pump or a second pump for backup, since pump ratings are measured under ideal conditions. Pair the pump with a float switch or choose an automatic model so it runs when water rises, even when you are away. Confirm voltage and the hose size fit your system. Review the product details before buying. With Rule bilge pumps, you keep your bilge dry and your boat protected.

Frequently Asked Questions

How do I size a bilge pump?

Size the pump to your hull and the water it must clear, with margin, since pump ratings are measured under ideal conditions and real-world output is lower. Many boats benefit from a larger pump or a second backup pump. Confirm voltage and hose size for your system.

What is a float switch?

A float switch turns the bilge pump on automatically when water rises in the bilge and off when it drops, so the pump runs when needed even while you are away. Pair a manual pump with a float switch, or choose an automatic pump with the switch built in.

Should I have a backup bilge pump?

A second bilge pump, mounted higher as a backup, adds protection if the primary pump fails or cannot keep up with serious water intake. Many boaters add a backup pump and switch for peace of mind. Size both to your hull and confirm wiring.
