Lead Free* MasterSeries In-Line Reduced Pressure Zone Detector Assembly Backflow Preventers (Type-II) with Flood Sensor - Large Diameter

MasterSeries LF866 Lead Free* reduced pressure detector 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 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. Check with local water authorities for installation requirements.
