What we do...

We test, maintain and repair backflow prevention assemblies

Cape Fear Public Utility Authority mandates annual testing of cross-connection control devices (backflow prevention assemblies).  This is to be done by a certified tester to ensure proper function.  Backflow poses potential danger risks as a result of possible contamination in the drinkable water supply. 

Cape Fear Backflow was founded by Shawn Mills, a NCRWA licensed backflow prevention tester.  Our service area includes Wilmington and the Cape Fear region with backflow testing for both commercial and residential properties.

  Failure to have your backflow preventer tested may result in a civil penalty and water service disconnection.

Affordable Backflow Testing

Our backflow testing is very reasonable at $30 for residential properties and $50 for commercial assemblies.
