994
Reduced Pressure Zone Assembly Backflow Preventers with Flood Sensor, Stainless Steel
Series 994 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 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. Check with local water authorities for installation requirements.
