WNC Backflow Testing & Prevention coordinates ASSE-certified backflow prevention assembly testing, differential pressure evaluations, and compliance reporting across Western North Carolina.
Backflow testing requires brief isolation of the assembly shut-off valves. Customers agree to provide clear physical access to the device and acknowledge that downstream water service will be temporarily suspended during the testing interval.
All tests are conducted in strict accordance with USC-FCCCHR, ASSE, and North Carolina DEQ cross-connection standards.
