Pick the San Diego backflow path that matches the problem
The city term helps discovery. The governing utility still decides the rule, submission method, tester route, and follow-up order.
San Diego annual backflow testing
Upon installation and annually thereafter San Diego says all backflow devices are tested annually and points customers to the approved tester list when the Public Utilities Department contacts them for compliance.
San Diego backflow reporting portal
Use the utility page to confirm whether reports go through BSI, WEIRS, SwiftComply, a city portal, or another official submission path.
San Diego approved backflow testers
This utility has an official tester-list route. Confirm status on the governing list before treating a provider as approved.
San Diego failed backflow test
Use the failed-test page when the assembly has already failed and the next step is repair, retest, and report submission.
San Diego irrigation backflow testing
Use this path when the question is tied to sprinkler systems, reclaimed water, outdoor service, or irrigation assemblies.
San Diego fire-line backflow testing
Use this path when the assembly serves fire protection equipment or a managed commercial site.

Support guides
Read these before acting on the San Diego workflow
How we verify local backflow rules
What counts as an official source, how local utility pages override generic assumptions, and how stale pages are re-verified.
Backflow reporting portals
How BSI, SwiftComply, and utility customer portals change the real testing workflow after the field work is done.
Anniversary date vs calendar deadline
Why some utilities track backflow tests by anniversary date, while others push owners into a calendar-season or hard-date deadline.
Residential vs commercial backflow rules
Why the local trigger is rarely just residential versus commercial, and how utilities actually split hazard, irrigation, multifamily, and managed-property cases.
