• Replaceable seats for an economical repair NPT inlet and outlet connections Assembled without shut-off valves Single access cover and modular check construction for the ease of maintenance Internal relief valve for reduced installation clearances Features an integrated flood sensor with SentryPlus™ alert technology to detect excessive water discharges from the relief valve Bronze body construction for durability Test cocks are screwdriver slotted

This 1-1/4 in reduced pressure zone assembly backflow preventer helps 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 and for contaminants at the service line entrance. This assembly without shut-off valves consists of a bronze body, NPT end connections, 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.
