Any water account connected to a well or water storage tank must install a reduced pressure backflow assembly or disconnect from the city water line. Source.

Testers must register on the Aquaresource portal with a copy of an accredited NC or UF TREEO tester certificate and a calibration report for each test kit, and city staff approve access. Source.

A tester who files a test more than 10 days late gets a final warning on the first offense and a 3 month suspension on the second. Source.

The Asheville backflow department runs the Cross-Connection Control Program, tracking every assembly and making sure each is tested annually by NC certified testers. Source.

From notice to filed report, the steps are the same everywhere: how a backflow test goes.
