Rule Industries 1222R 1-Inch Check Valve for Bilge Pumps

The Rule Industries 1222R is a replacement check valve designed specifically for marine bilge pump systems. This essential component prevents backflow of water into the bilge after the pump has discharged, ensuring your bilge stays dry and reducing unnecessary pump cycling.

Key Features:

• 1-inch (25mm) port size with 1-inch flange connection
• Compatible with Rule 800 and 1100 GPH bilge pumps including RM800B, RM800B-24, RM1100B, and RM1100B-24 models
• Non-return joker valve design controls backflow effectively
• Durable construction suitable for harsh marine environments
• Easy installation with standard hose connections
• Lightweight design at approximately 0.02 lbs

This check valve is an important accessory for Rule-Mate automated bilge pump systems, helping to maintain optimal pump performance and extend equipment life. The valve ensures one-way flow, preventing discharged water from returning to the bilge when the pump shuts off. Note that a like-sized barbed port must be purchased separately for installation.
