Who regulates backflow tester certification in Arizona

Arizona sets baseline rules at the state level, but some local jurisdictions add their own requirements on top. Check both the state agency and your local water purveyor.

The authority for backflow tester credentials in Arizona is Arizona Department of Environmental Quality (ADEQ). A.A.C. R18-4-215(F) requires certification from the CA-NV Section of AWWA, the Arizona State Environmental Technical Training (ASETT) Center, or another ADEQ-approved certifying authority. ADEQ does not run one unified program itself, so cycle/CE/fee are set independently by each approved body; a commonly cited "3 years" figure appears only on third-party training-vendor marketing pages, not an ADEQ or state source, so it is excluded here.

How often you need to renew

Arizona Department of Environmental Quality (ADEQ) does not publish a fixed statewide renewal cycle online. Contact the agency to confirm your renewal date.

Continuing education and retesting requirements

Arizona Department of Environmental Quality (ADEQ) does not publish continuing education requirements online. Confirm with the agency before your renewal date.

Renewal deadline and grace period

The agency does not publish a formal grace period online. Treat your expiration date as hard: Water purveyors generally stop accepting test reports from testers whose certification has lapsed, and many jurisdictions require retaking the full certification course instead of a simple renewal once the credential expires. Confirm the exact grace period, if any, with Arizona Department of Environmental Quality (ADEQ) well before your expiration date.

How to renew, step by step

  1. Confirm your exact expiration date on your certification card or with Arizona Department of Environmental Quality (ADEQ).
  2. Complete any required refresher course or continuing education for your jurisdiction.
  3. Submit the renewal application to the agency before the deadline.
  4. Keep your test kit calibration certificate current: most jurisdictions require annual gauge calibration alongside a valid tester credential.
