How often does a backflow preventer need to be inspected?
Backflow preventers should be checked during your regular plumbing inspection, and we include backflow checks in our Priority Plan’s annual maintenance. Exact testing intervals can vary by local rules and system risk. Our licensed plumbers inspect for pressure issues, cross-connection hazards, and signs of backflow during visits. If your home uses a well or pump system, we also look for leaks or backflow as part of that assessment.

How much does it cost to replace a backflow preventer?
We don’t publish a flat price for backflow preventer replacement. A licensed tech confirms the cost after an on-site inspection and diagnosis. Expect upfront, itemized pricing before work begins.

All workmanship includes a 2-year warranty, or 4 years for Priority Plan members. We serve homes in Bellingham, MA and nearby Franklin, MA.
