The FEBCO MasterSeries line of backflow preventers are designed to serve a wide range of applications including fire suppression systems, potable water supplies, and agricultural and municipal irrigation.

Select MasterSeries models come with SentryPlus Alert® technology to detect excessive water discharges from the relief valve. When activated through an add-on sensor connection kit, the integrated flood sensor can trigger the alert system to notify personnel about potential flooding. Add-on sensor connection kits are available for BMS and cellular communication.
