How to become a backflow tester in Louisiana
Louisiana recognizes backflow testers at the state level. Licensed plumbers and irrigators add the Water Supply Protection Specialist (WSPS) endorsement by obtaining a backflow tester certification from a Board-approved provider, and the Board accepts all tester certifications issued by ASSE or ABPA, while non-plumbers seeking tester-only status are directed to the Louisiana Department of Health.

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.
