What Is Backflow Testing?

Backflow testing verifies that your backflow preventer is working properly to protect the public water supply from contamination. Devices such as RP, DC, and PVB assemblies must be tested annually and reported to the appropriate authority. A failed test requires repair and retesting to remain in compliance.
