This 1 1/4 in lead-free copper silicon alloy reduced pressure zone backflow preventer assembly is designed to prevent the flow of polluted water from entering into the potable water supply due to back siphonage and or back pressure 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 and for contaminants at the service line entrance. This assembly consists of a lead-free body, NPT end connections, 1/4-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 includes 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.
