The main function of a backflow valve is to stop water from backing up into the piping system. Backflow valves utilize check valves, air inlets, and relief valves. The Health Department or local water supplier decides when and where backflow valves are needed.
Backflow valves must pass rigorous tests to be approved for use and are required by law to be tested annually by a certified tester to ensure that they are in proper working order. If a backflow valve does not meet the minimum testing requirements it must be repaired and retested.
