Backflow Information
Backflow prevention assemblies protect the public water supply by stopping contaminated water from moving backward into clean lines. Commercial properties are commonly required to test and certify those assemblies every year.
What Certification Confirms
Device performance: A certified tester verifies that check valves, relief valves and shut-off valves are working as intended for the specific assembly type.
Required documentation: The test creates a record for the owner and the water authority. When repairs are needed, the report identifies what failed and what needs to happen next.
Consequences of Missing Certification
Missing a backflow certification can lead to late notices, fines, compliance violations or water service issues depending on the local authority. It can also leave a property without proof that the assembly is protecting the water supply.
How AO Helps
AO performs annual testing for domestic, irrigation and fire-line devices, submits reports directly where required, and helps coordinate repair or replacement when a device fails.
