Description

The Colt 8 inch stainless steel reduced pressure detector backflow preventer assembly offers critical protection against the reverse flow of non-potable water and fire protection substances into potable water supplies. It features a durable 304 stainless steel body, OSY resilient seated gate valves, and groove couplings for straightforward installation. An integrated SentryPlus Alert® flood sensor detects relief valve discharge, providing advanced leak detection capabilities when paired with an optional connection kit. This assembly is approved by FCCCHR-USC, AWWA, UL, and FM, ensuring reliable performance in health hazard cross-connection applications, including fire sprinkler systems.

Help Me Connect

This 8-inch reduced pressure detector backflow preventer assembly is designed for installation in horizontal pipelines. Its groove couplings facilitate easy integration and precise pipeline alignment. The assembly includes domestic OSY resilient seated gate valves for secure shutoff.

The integrated SentryPlus Alert® flood sensor requires an add-on connection kit (sold separately) for activation and communication. These kits enable connection to Building Automation Systems (BAS) via RS-485 Modbus, cellular communication, or Wi-Fi through the Nexa® platform or Sensor Control Monitor, allowing for remote monitoring and alert delivery for potential flooding events.
