What to check for Anaheim

Anaheim's published irrigation standards explicitly require backflow protection to keep irrigation systems from contaminating the public water supply.

  • Due basis: Anaheim says backflow prevention devices must be tested annually, and repaired and retested if defective. The annual tests must be performed by an Orange County Health Care Agency certified tester carrying a valid City of Anaheim business license.
  • Who is affected: Water users at locations where Anaheim requires a backflow prevention device, especially commercial, multi-family, irrigation, and fireline-related services.
  • Program phone: 714-765-4173
Local signals

Signals that matter before you act

  • Anaheim's landscape and water standards call for backflow devices on irrigation projects.
  • The city routes irrigation users into the broader cross-connection control rules instead of treating irrigation as separate filler content.
  • Annual testing still sits inside the same approved-tester workflow.
Workflow

Anaheim workflow order

  1. Confirm whether the project or site uses an irrigation connection that requires device protection.
  2. Use an Anaheim-approved tester when the assembly comes due.
  3. Keep the result inside Anaheim's approved reporting path so the device stays compliant.
