Backflow Repair & Replacement in Apex, NC

A backflow assembly that fails its annual or three-year test is not automatically a replacement. Most failures in Apex trace back to a few worn internal parts — a check disc that no longer seats, a tired spring, a relief valve that weeps, or a fouled seat after years of Jordan Lake water cycling through it. We open the assembly, find what failed, and rebuild it with the manufacturer’s repair kit whenever that restores it to a passing test.

When repair stops making sense

Sometimes the body is cracked, the assembly is obsolete, or the rebuild cost approaches the price of a new unit. That is common with the original assemblies in established subdivisions like Bella Casa and Scotts Mill, where systems installed during the 1990s–2000s build-out are now well past their service life. In those cases we replace with a like-for-like or upgraded assembly sized to your line, set it to code, and retest on the spot so the new unit goes into the record clean.

Every repair or replacement ends the same way: a fresh test, a passing result, and the certified report submitted to the Town of Apex promptly. Whether you are in a 2010s new-construction pocket off the Peakway or an older corner of town, you get one call, one visit, and a closed-out compliance file.

Apex runs its own cross-connection control program. Your water is treated at the jointly-owned Cary/Apex plant drawing from Jordan Lake, and the Town — not the county or state directly — sets and enforces the testing schedule for assemblies on its system.

Commercial assemblies must be tested annually. Under NC SB 166, residential irrigation assemblies now test every three years, while booster-pump and chemical-feed assemblies stay on an annual cycle. Submission windows and reporting deadlines are set by the Town and can change, so the certified tester confirms the current filing process with Apex before submitting the passing report electronically.

That matters for repairs because a failed test starts a clock. When we rebuild or replace your assembly, we retest immediately and file the passing report right away, so a failure never turns into a compliance lapse with the Town.
