About Backflow Assemblies
A backflow device assembly, a device incorporated in your water system and commonly associated with fire sprinkler and irrigation systems, allows water to move in one direction and helps prevent potentially contaminated water from entering the drinking water system of a dwelling or the City water supply. Other applications of backflow assemblies include boilers, pools, and some humidifiers.
