Pick the Pasadena 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.
Pasadena annual backflow testing
Annually and whenever the assembly fails or is replaced 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.
Pasadena backflow tester options
This route is clearly labeled as non-official provider discovery and should come after the utility workflow.
Pasadena failed backflow test
Use the failed-test page when the assembly has already failed and the next step is repair, retest, and report submission.
Pasadena irrigation backflow testing
Use this path when the question is tied to sprinkler systems, reclaimed water, outdoor service, or irrigation assemblies.
Pasadena fire-line backflow testing
Use this path when the assembly serves fire protection equipment or a managed commercial site.

Check the local rule before treating this as a generic tester search
- Cadence: Annually and whenever the assembly fails or is replaced
- Due basis: 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.
- Notice or device clue: Look for the utility name, service address, assembly serial number, account or notice ID, and due date.
- Submission: Pasadena Water and Power backflow program
- Acceptance rule: Use the listed submission method and keep proof that the report was filed with the utility.
- Cost signal: Testing is market-priced, and Pasadena's main local friction is staying inside the due-date and county-certified tester workflow.

Source-backed workflow
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.
