LF009 Watts 3" Cast Iron Backflow Preventer With Flood Sensor Less Valves

This 3 inch 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. 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 shutoff valves consists of a cast iron 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. The coating on this backflow assembly uses ArmorTek, a patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion. 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.
