Reduced Pressure Zone Assembly Backflow Preventers with Flood Sensor, Stainless Steel - Sizes 2 1/2 – 10 IN - 994-FS

Series 994-FS reduced pressure zone assembly backflow preventers help stop the reverse flow of polluted water into the potable water supply due to backsiphonage and or backpressure. Designed for health hazard applications. Check with local water authorities for installation requirements. Maximum Working Pressure: 175 psi (12.06 bar).

This series features an integrated 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.
