This Colt™ 6 inch reduced pressure detector backflow preventer assembly is designed to protect potable water supplies from dangerous cross-connections. It prevents the reverse flow of fire protection substances and non-potable water into the potable water supply due to backsiphonage or backpressure.

Primary Use

• Ideal for health-hazard non-potable service applications such as fire sprinkler systems, irrigation, or industrial processing.
• Monitors unauthorized use of water from the fire protection system.

Features

• Features an extremely compact design, approximately 70% lighter than traditional designs.
• Includes drip tight shutoff valves and groove couplings for easy installation and pipeline alignment.
• Patented link check for lowest pressure loss and unmatched ease of serviceability.
