Rule Industries 1221R Check Valve 3/4 Inch for Bilge Pumps

The Rule Industries 1221R is a 3/4-inch inline check valve designed specifically for bilge pump discharge systems. This essential component prevents water from flowing back into the bilge area after the pump has shut off, ensuring your vessel stays dry and your pump operates efficiently.

Key Features:

• 3/4-inch barbed hose connections for secure attachment to standard bilge pump discharge hoses
• Durable marine-grade construction resists corrosion in harsh saltwater and freshwater environments
• Spring-loaded valve mechanism ensures reliable one-way flow
• Compact design allows for easy installation in tight engine compartments
• Clear housing permits visual inspection of valve operation

This check valve is an essential component for any bilge pump installation, protecting against back-flow that can cause premature pump cycling and reduced battery life. The barbed fittings provide a secure connection when used with proper hose clamps.
