Water departments and municipal authorities across Western North Carolina mandate that all commercial, multi-family, irrigation, and dedicated fire service backflow prevention assemblies undergo mandatory annual performance testing. Our ASSE and state-certified backflow testers conduct precision differential pressure field tests, verify check valve tightness and relief valve opening thresholds, and deliver official certified test documentation directly to your municipal water purveyor before annual cutoff dates.
Our certified technicians utilize NIST-calibrated 5-valve differential pressure test kits to evaluate valve operation under real-world hydraulic conditions. We record static line pressure, Check Valve 1 and Check Valve 2 pressure drops, and verify the precise differential threshold at which the relief valve discharges.
Failing to submit certified annual test results can trigger water service shutoff notices and administrative fines from municipal water authorities. We handle the entire compliance pipeline, completing official test forms and submitting verified documentation directly to City of Asheville Water Resources, City of Hendersonville Water & Sewer, Maggie Valley Sanitary District, and regional utilities.
If an assembly fails its annual differential test due to mineral buildup, grit wedging, or disc degradation, our service vehicles carry complete OEM repair kits for Wilkins, Watts, Febco, Apollo, and Ames assemblies. We disassemble, clean, rebuild, and re-test on the same visit to maintain water service continuity.
For property management companies, healthcare campuses, retail centers, and industrial facilities with multiple containment assemblies, we provide centralized scheduling, digital asset tracking, and comprehensive compliance logging across all Western North Carolina corridors.
Our technicians arrive with calibrated 5-valve test equipment and file your official compliance report directly with your municipal water purveyor.
Schedule Same-Day / Priority InspectionNorth Carolina Rules Governing Public Water Systems (15A NCAC 18C) and local cross-connection control ordinances require annual testing to ensure mechanical backflow preventers continue functioning properly. Over time, internal springs fatigue, mineral scale accumulates, and rubber discs deteriorate, creating dangerous cross-connection hazards if line pressure fluctuates.
If the differential pressure across a check valve falls below code minimums (typically 1.0 to 2.0 PSI) or the relief valve fails to discharge at least 2.0 PSI below supply pressure, the assembly fails. Our technicians can clean internal components, replace worn rubber seats and springs on the spot, and perform an immediate re-test.
We submit digital and physical compliance certificates to your specific municipal water provider (such as Asheville Water Resources, Hendersonville Water, or Waynesville Utilities) within 24 to 48 hours of completing the test, providing you with a signed copy for your facility records.
