Description

The FEBCO 1/2 inch LF860 Reduced Pressure Zone Backflow Preventer Assembly is designed for health-hazard applications, preventing the reverse flow of high hazard (toxic) fluids into potable water supplies. It features Lead Free* bronze construction and threaded quarter turn ball valves. An integrated SentryPlus Alert® flood sensor detects excessive relief valve discharges, and with an add-on connection kit, can send alerts to facility personnel or integrate with building management systems via Wi-Fi or Modbus. This assembly is ideal for industrial plants, hospitals, and critical water lines, offering maximum protection against backpressure and backsiphonage. Item number F683000.

Help Me Connect

This 1/2 inch FEBCO LF860 Reduced Pressure Zone Backflow Preventer Assembly features threaded quarter turn ball valves for connection into your water system. It includes top-mounted test cocks for easy testing and maintenance. The integral flood sensor requires an add-on connection kit (sold separately) to enable communication and send alerts via BMS, cellular communication, or through the Sensor Control Monitor for BAS/Nexa platform integration. This assembly is designed to protect potable drinking water systems from high hazard cross-contamination.

Additional Details

This 1/2 inch lead free reduced pressure zone backflow preventer assembly prevents the reverse flow of high hazard (toxic) fluids from entering a potable water supply due to backsiphonage or backpressure. It is designed for critical applications in industrial plants, hospitals, and water systems requiring maximum protection.

Key Features

  • Equipped with a flood sensor featuring SentryPlus Alert® technology to detect excessive water discharges from the relief valve.
  • Requires an add-on connection kit to activate the flood sensor and relay alerts for potential flooding events.
  • Supports integration with BMS (Building Management Systems) via cellular communication or a Sensor Control Monitor for BAS via RS-485 Modbus or the Nexa® platform via Wi-Fi.
  • Features Lead Free* construction, with wetted surfaces containing less than 0.25% lead by weight.
  • Designed for easy maintenance with modular relief valve and check valves.
  • Includes threaded quarter turn ball shutoff valves and top-mounted test cocks.

An add-on connection kit is required to activate the flood sensor's communication features; without it, the sensor is a passive component. Watts® is not responsible for the failure of alerts due to connectivity or power issues. Proper drainage must be provided for discharge events.
