Series 957-FS reduced pressure zone assembly backflow preventers help stop the reverse flow of liquids due to backpressure or backsiphonage, where potential health hazard exists.
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.
