Testing cadence

Annual or event-based timing

Pasadena Water and Power customers where the utility requires a backflow assembly, including irrigation, fire-service, commercial, industrial, medical, hospitality, and multifamily properties.

  • 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.
Penalty exposure

Non-compliance penalties

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.

  • 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.

Residential notes

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 focus

Commercial and managed properties

  • 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.

Market cost analysis

Local cost band

Typical testing and repair pricing used to frame next-action decisions in the metro around this utility.

Testing Testing is market-priced, and Pasadena's main local friction is staying inside the due-date and county-certified tester workflow.
Repair and retest Repair and retest cost depends on the device and whether a C36 plumbing contractor is needed for the repair.
