Backflow Repair & Replacement in Carrboro, NC

Most backflow repairs in Carrboro start the same way: an annual OWASA test comes back failed, and the report lands on your desk with a deadline attached. The good news is that a failed test almost never means the whole assembly is junk. It usually means one or two internal parts have worn out — a check that no longer seats, a relief valve that weeps, a spring that has lost tension — and those are exactly the parts we rebuild.

Repair first, replace only when it makes sense

We carry rebuild kits for the assemblies common around here, from the older lines feeding early-1900s mill houses near Carr Mill to the irrigation backflows on 1990s and 2000s subdivisions out toward Quarterpath Trace and Claremont. If your unit can be brought back to a passing test with new checks, seats, and a relief valve, that is almost always the faster and lower-cost path. We open it up, replace the worn internals, and re-test on the spot.

Replacement is the right call when the body itself is cracked or corroded, when parts are no longer made for an obsolete model, or when the assembly has failed repeatedly and a rebuild would not hold. In those cases we install a like-for-like, properly sized unit, set it at the correct height and orientation, and verify it passes before we leave Plantation Acres or wherever your meter happens to sit.

Carrboro’s water is managed by OWASA, the Orange Water and Sewer Authority — the community-owned utility that serves both Carrboro and Chapel Hill. OWASA requires backflow assemblies to be tested annually by default, which is how most failed assemblies first come to light.

There is one common exception: an irrigation system with no chemical feed and no booster pump may qualify for testing every three years rather than every year. Either way, when an assembly fails and we repair or replace it, a certified tester reports both the test and the repair results to OWASA within 10 business days. We handle that filing for you, so the only thing you have to do is approve the work.

If you are not sure which testing cycle applies to your property — an irrigation line in Lake Hogan Farms versus a domestic assembly on an older Carr Mill home, for instance — we confirm it with OWASA as part of the job.
