How often do backflow preventer valves need to be replaced?

There is no set replacement timeline for backflow preventer valves. Replace the unit when annual testing finds a failure, leaks, or freeze damage. Most municipalities require annual testing to stay compliant. Many valves can be rebuilt with new seals and springs. A cracked body (often from freezing) requires full replacement. Annual inspection before irrigation season is smart. We install, repair, and certify RPZ and vacuum breaker devices for homes and businesses in Denver and nearby cities.
