This 1 1/4 inch 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. It includes a flood sensor with SentryPlus Alert technology to detect water discharges from the relief valve, providing crucial safety monitoring for continuous pressure piping applications and health hazard cross-connections.

Flood Sensing & Alerting

• Features a flood sensor with SentryPlus Alert technology to detect continuous discharge from the relief valve.
• When paired with an add-on connection kit (sold separately), the sensor activates to relay alerts for potential flooding events.
• Integrates with the Sensor Control Monitor to deliver maintenance alerts to a Building Automation System (BAS) via RS-485 Modbus or to the Nexa platform by Wi-Fi connectivity.
