Backflow Prevention Testing Requirements in California
California Cross-Connection Control Policy Handbook §3.3.3 — which replaced CCR Title 17 in 2024 — requires annual backflow preventer testing on all fire service connections, enforced by the local water utility rather than the fire department. Double-check detector assemblies (DCDA) and reduced-pressure detector assemblies (RPDA) on fire lines must pass annual certification or face water service shutoff. San Francisco mandates correction within 30 days of a failed test (SFPC §1312.1), and most Bay Area utilities charge $150 to $300 for the utility-administered retest.
