1 1/2 IN Lead Free Reduced Pressure Zone Backflow Preventer Assembly, Quarter Turn Ball Valves, Bronze Strainer, Air Gap Fitting, Backflow Flood Sensor

This 1 1/2 inch lead free reduced pressure zone backflow preventer assembly includes a flood sensor with SentryPlus Alert(R) technology to detect water discharges from the relief valve. When activated through an add-on sensor connection kit, the flood sensor can send an alert to notify facility personnel about potential flooding. Add-on sensor connection kits are available for BMS and cellular communications. This assembly is designed to prevent the flow of polluted water from entering the potable water supply due to backsiphonage and or backpressure. Includes bronze strainer and air gap fitting. Ideal for protection in continuous pressure piping applications and at cross-connections identified as health hazards and from other contaminants found at the service line entrance.
