This Colt™ 6 inch reduced pressure detector backflow preventer assembly (RPDA) is designed to prevent the reverse flow of fire protection substances and non-potable water into the potable water supply due to backsiphonage or backpressure. This assembly is suitable for health-hazard non-potable service applications such as irrigation, fire line, or industrial processing.

This compact modular design is approved for horizontal Z pattern installation and features a 304 (Schedule 40) stainless steel body with a quick access sleeve. It includes torsion spring check valves, grooved gear operated butterfly valves with tamper switch, test cocks, and a corrosive resistant bottom mounted pressure relief valve. A cubic feet per minute meter is furnished to detect underground leaks and unauthorized water use. This backflow assembly contains a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve, which can relay alerts for potential flooding events when paired with an add-on connection kit.

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