How to become a backflow tester in North Carolina
North Carolina splits tester recognition between the state and local water purveyors. North Carolina's WTFOCB administers a state Cross-Connection operator certification (required for distribution systems with five or more testable backflow assemblies under 15A NCAC 18D) with Board-approved certification schools, while acceptance of individual assembly testers is otherwise determined by local water systems' cross-connection control programs.

The path, wherever you are
- Confirm which certifications the authority and your target purveyors accept.
- Complete a recognized tester course, typically a multi-day class ending in a written exam and a hands-on practical on the main assembly families. The ASSE 5110 requirements are the national reference point.
- Register with the authority or each purveyor, per their process, and keep your gauge calibration documented.
- Renew on the recert clock before it lapses: the two-clock sheet makes the schedule automatic, and backflow tester recertification explains the three-year cycle.
Before committing, read what backflow testing pays andhow to become a backflow tester, which walks the course, exam and practical that every state path runs through.
