Pasadena utility backflow testing requirements
Pasadena is a strong Los Angeles-area page because the utility publishes real annual-testing and failed-test workflow, but the tester route is county-certified rather than city-approved.
Fast answer
Who, when, and what device?
Pasadena Water and Power says each backflow prevention assembly is tested at least once a year by the due date on the PWP notice. The utility tells customers to use a Los Angeles County certified backflow prevention testing business and to send the passing report plus any repair documentation back to PWP.
- Who is affected
- Pasadena Water and Power customers where the utility requires a backflow assembly, including irrigation, fire-service, commercial, industrial, medical, hospitality, and multifamily properties.
- Covered devices
- Backflow prevention assemblies · Irrigation devices · Fire-service devices · Containment assemblies required by PWP
- Risk if missed
- Pasadena says late reports can trigger follow-up notices and extra fees. Failed assemblies must be repaired by a C36 plumbing contractor and the passing retest sent back to PWP before the matter is treated as closed.

Program and failure notes
- Pasadena expects annual testing by the due date on the utility notice.
- Failed assemblies must be repaired and the passing retest sent back to PWP.
- The tester route is county-certified and should not be presented as a Pasadena approved list.
- Each assembly is tested at least once a year.
- PWP points users to Los Angeles County certified testing businesses instead of a Pasadena-only approved list.
- Failed tests require repair and a passing retest before the record is closed.
Residential notes
- Residential intent is strongest when the property has irrigation, a fire service, or another utility-triggered hazard.
- Pasadena still routes customers through the utility notice and county-certified tester directory instead of a city-approved list.
Commercial notes
- Commercial value is strong because Pasadena names the hazard-heavy property types directly on the program page.
- The city also publishes failed-test repair and resubmission rules instead of stopping at generic education.
Irrigation
Pasadena is useful for irrigation demand because the utility explicitly lists irrigation services as one of the local trigger categories for containment devices.
- Irrigation is named directly on the program page, not implied.
- The same annual due-date logic still applies.
- Customers still need county-certified testing businesses for the work.
Fire line
Pasadena explicitly calls out fire services as part of the cross-connection control program, so fire-line demand belongs on the utility page rather than a generic plumbing page.
- Fire services are named directly on Pasadena's program page.
- Failed fire-service assemblies still need repair and a passing retest.
- County-certified testers are the practical routing layer, not a Pasadena-approved list.
Cost and fee context
Testing is market-priced, and Pasadena's main local friction is staying inside the due-date and county-certified tester workflow.
Repair and retest cost depends on the device and whether a C36 plumbing contractor is needed for the repair.
This utility is a good directory-only market because the utility publishes the rules while county certification supplies the tester layer.
Evidence ledger
Official sources
Pasadena is a strong California utility because it publishes annual due-date testing, failed-test repair workflow, explicit high-hazard property examples, and directs customers to the Los Angeles County certified tester directory rather than pretending there is a Pasadena-only approved list.
