Backflow Tester Certification Renewal, State by State

Backflow prevention assembly testers must renew their certification on a schedule set by their state or local authority. The cycle, the continuing education hours, and the fees vary widely: some states renew every 2 years, others every 3, and a few leave the rules entirely to local water purveyors.

This site compiles the renewal requirements for 26 states in one comparable format: regulating agency, renewal cycle, CE hours, and fees, each verified against the official agency source and dated.

How this data is compiled

Every figure is taken from the official page of the state agency (or its designated training provider) and carries a last-verified date. When an agency does not publish a figure, we say so instead of guessing. Details on the methodology page.
