How often does a backflow preventer need to be inspected?
Backflow preventers should be inspected and tested once per year to stay compliant with local regulations. Expect a county notice about 45 days before your deadline. Our certified plumbers typically complete the test in about 30 minutes when no issues are found, check for valve leaks, and submit the report to the county for compliance. We service homes and businesses across Denver, Highlands Ranch, and nearby areas.
