How do I become a certified backflow tester in Oklahoma?

In Oklahoma, individual water purveyors decide which tester certifications they accept. Oklahoma DEQ's public water supply rules (OAC 252:626/252:631) require backflow prevention but establish no state tester license, so individual cities and water purveyors decide which tester certifications they accept. Complete a recognized tester course with its written and hands-on exams, then register with the authority or purveyors you will test for.
