A backflow prevention device generally needs to be tested at least once a year, although the exact frequency depends on local regulations, the type of assembly, and the property's water system. Regular testing helps ensure the device prevents contaminated water from flowing backward into the public drinking water supply. In Louisville, CO, property owners should confirm the testing schedule and reporting requirements with the local water utility, as requirements may vary depending on the property and installation.

Annual testing is especially important for commercial buildings, multifamily properties, irrigation systems, and other facilities with backflow prevention assemblies. Testing should also be performed after a new device is installed, following certain repairs or replacements, and whenever required by the local water authority. A certified backflow tester typically inspects the assembly, checks whether its internal components operate correctly, and measures performance according to the applicable testing procedure. If the device fails, it may need repair or replacement, followed by another test to verify that it functions properly.
