This Colt™ 8 inch reduced pressure detector backflow preventer assembly is designed to prevent the reverse flow of fire protection substances and water of non-potable quality into the potable water supply due to backsiphonage or backpressure. It is ideal for protection at health hazard cross-connections, such as on fire sprinkler systems and at service line entrances.

A WARNING: It is illegal to use this product in any plumbing system providing water for human consumption, such as drinking or dishwashing, in the United States. Always consult your local water authority, building, and plumbing codes before installation.

The C500 Reduced Pressure Detector Assembly offers protection for drinking water supplies from dangerous cross-connections, adhering to national plumbing codes and water authority requirements for health-hazard non-potable service applications like irrigation, fire lines, or industrial processing. This model includes a SentryPlus Alert® flood sensor to detect excessive water discharges from the relief valve.
