California backflow certification requirements

California regulates cross-connection control through the Cross-Connection Control Policy Handbook. Public water systems must use backflow assembly testers and cross-connection control specialists certified by recognized or accredited organizations for compliance.

Certification authority

State Water Resources Control Board, Division of Drinking Water

Backflow certification can involve state drinking-water rules, plumbing or building-code rules, health department oversight, and local water supplier acceptance. Confirm the exact path with the official sources below before paying for training or registering for an exam.

What to verify

  • Check the current State Water Board recognition and accreditation transition rules before choosing a certifying organization.
  • Expect separate roles for backflow prevention assembly testers and cross-connection control specialists.
  • Public water systems and local programs may still set accepted reporting procedures and tester-list requirements.

Study recommendations

  • Study the CCCPH definitions for backflow, backpressure, backsiphonage, user supervisors, hazards, and tester responsibilities.
  • Know the difference between tester certification and training-course completion.
  • Review how containment protection fits into public water system compliance.

Important local-program note

A person may complete a training course and still need approval, listing, reporting access, or recognition from a local water supplier or authority. Treat this page as a starting point, then verify the current rule, accepted credentials, forms, and renewal process with the official agency.
