1" LF919-QT Lead Free Reduced Pressure Zone Assembly w/ Flood Sensor Connectivity

This 1" lead free reduced pressure zone backflow preventer assembly is designed to prevent the flow of polluted water from entering the potable water supply due to backsiphonage and or backpressure. 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. This assembly includes a flood sensor with SentryPlus Alert® 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. Sensor activation requires purchase of an activation kit which can be connected to existing building and irrigation management systems.
