Backflow Testing questions from Denver homeowners

Who needs annual backflow testing in Denver?

Any property with an irrigation system, a fire suppression system, a boiler, a commercial dishwasher, or any other connection that could allow water to flow back into the public supply typically requires a certified annual test.

What happens if a backflow preventer fails its test in Denver?

A failed device must be repaired or replaced and retested before certification is issued. Operating without a valid certificate can trigger a water service shutoff. A licensed plumber handles both the test and any required repair in the same visit.
