Additional Details

The Colt 3 inch lead free reduced pressure zone backflow preventer assembly protects potable water systems from contamination due to backsiphonage or backpressure, preventing reverse flow of fire protection substances and non-potable water.

It features non-rising stem (NRS) shutoff valves and is approved for horizontal N pattern installation.

Key Features

  • Includes a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve.
  • Requires an add-on connection kit to activate flood sensor alerts via BMS, cellular communication, or Sensor Control Monitor for integration with BAS (RS-485 Modbus) or Nexa® platform (Wi-Fi).
  • Constructed with a Type 304 (Schedule 40) stainless steel housing and sleeve for durability.
  • Extremely compact design, 70% lighter than traditional designs.
  • Torsion spring check modules and groove couplings for ease of serviceability and installation.
  • Lead Free* construction, with wetted surfaces containing less than 0.25% lead by weight.

Note: An add-on sensor connection kit is required to activate the flood sensor. Without the connection kit, the flood sensor is a passive component and will not communicate with any other device.
