Pick the Tempe 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.
Tempe annual backflow testing
At installation and annually on the anniversary date Tempe uses annual anniversary-date testing by a City-registered certified tester, sends reminders before the due date, and can escalate unresolved noncompliance to termination of water service.
Tempe approved backflow testers
This utility has an official tester-list route. Confirm status on the governing list before treating a provider as approved.
Tempe failed backflow test
Use the failed-test page when the assembly has already failed and the next step is repair, retest, and report submission.
Tempe irrigation backflow testing
Use this path when the question is tied to sprinkler systems, reclaimed water, outdoor service, or irrigation assemblies.
Tempe fire-line backflow testing
Use this path when the assembly serves fire protection equipment or a managed commercial site.
