Reduced Pressure Detector Assembly Backflow Preventers with Flood Sensor, Stainless Steel – Sizes 2 1/2 – 10 IN
Series 957RPDA-FS reduced pressure detector assembly backflow preventers help stop the reverse flow of fire protection system substances being pumped or siphoned into the potable water supply. A meter incorporated to detect ground leaks and unauthorized illegal taps greatly reduces annual water expenses. 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.
