How often does a backflow preventer need to be inspected?

Most backflow preventers should be inspected and tested on a schedule set by your local water provider. The required timing can vary by city, device type, and hazard level. In the Dallas–Fort Worth area, our licensed plumbers confirm the correct interval and provide documentation after testing. We perform work with required permits and follow local rules. A technician will confirm your due date on site and tag the assembly.

Quick checks:

• Check the test tag for the last test date.
• Look for notices from your water provider.
• Schedule a test after any repair or relocation.
