Rule Industries Check Valve Marine Bilge Pump

The Rule Industries Check Valve is a replacement bilge pump check valve (also called a bilge pump backflow preventer) for Rule marine bilge pumps. It fits in the discharge line. It helps stop water from flowing back into the bilge after the pump shuts off. That cuts down on pump cycling and keeps the bilge drier.

Key Features:

• One-way design that helps prevent water from flowing back into the bilge
• Made for Rule bilge pump discharge ports, including Rule-Mate series pumps
• Made in the USA by Rule, a long-established name in marine pumps
• Available in several port sizes to match different Rule pump models
• Simple to install in the discharge plumbing

A check valve is a low-cost addition to a bilge pump setup. It helps the pump work more reliably and avoid needless cycling. Choose the size that matches your pump's discharge port.
