• Features an integrated flood sensor with SentryPlus™ alert technology to detect excessive water discharges from the relief valve Single access cover and modular check construction for the ease of maintenance NPT inlet and outlet connections with Viega ProPress® adapters Internal relief valve for reduced installation clearances Quarter-turn full port resilient seated ball valve shut-off Lead-free bronze body construction for durability

This 1-1/2 in lead-free reduced pressure zone backflow preventer assembly is designed to prevent the flow of polluted water from entering into the potable water supply due to backsiphonage and or backpressure in accordance with national plumbing codes and water authority requirements. Its compact modular design facilitates easy maintenance with a single-access cover for in line repairs. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as health hazards. This assembly consists of a lead-free bronze body, NPT end connections with Viega ProPress® adapters, quarter-turn ball valve shut-off with tee handles, top-mounted test cocks, two-in-line independent check valves, captured springs and replaceable check seats with an internal relief valve for reduced space requirements. This backflow assembly contains an integrated flood sensor with SentryPlus™ alert technology to detect excessive water discharges from the relief valve. When activated through an add-on sensor connection kit, the flood sensor can send an alert to notify the user of potential flooding. Add-on sensor connection kits are available for both BMS and cellular communications.
