LF909 Small
Lead Free* Reduced Pressure Valve Assembly Backflow Preventers with Flood Sensor - Small Diameter 3/4 - 2 IN Sizes
Series LF909 Small Lead Free* Reduced Pressure Zone assemblies feature a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve. Activated through an add-on connection kit, the sensor can trigger the alert system sending notification of flood detection to facility personnel. Connection kits are available for BMS and cellular communication.
This series prevents the reverse flow of contaminated water caused by backsiphonage or backpressure from entering the potable water supply. Ideal for protection at health hazard cross-connections or for containment at the service line entrance. Its compact modular design facilitates maintenance and assembly access. Check with local water authorities for installation requirements.
