How do I become a certified backflow tester in Maine?

In Maine, individual water purveyors decide which tester certifications they accept. Maine's Cross Connection Rules (10-144 CMR Chapter 226) require public water systems to run cross-connection control programs with backflow preventers tested as required by the Maine State Internal Plumbing Code or by the public water supplier, and the state names no tester certification of its own. Complete a recognized tester course with its written and hands-on exams, then register with the authority or purveyors you will test for.
