What happens if a backflow device fails?
The device must be repaired or replaced and retested before certification can be completed.
Certified backflow testing
Annual Backflow Certification
Certified annual backflow testing and reporting for commercial domestic, irrigation and fire-line assemblies.
Quick answer
Who needs annual backflow certification?
Commercial properties with backflow prevention assemblies are commonly required to test and certify those devices every year. AO performs certified testing for domestic, irrigation and fire line assemblies, documents pass or fail results and helps with report submission where required.
Common questions
Do water districts have different rules?
Yes. Local utilities may have different due dates and submission processes. AO can review the notice or account details and confirm the applicable testing deadline and submission requirements.
Certified testing and reporting
Keep annual backflow testing and reporting on schedule.
AO performs certified testing, documents pass/fail results, submits reports where required and identifies needed repairs before a missed due date creates a water-utility compliance issue.
