Why annual testing matters
Backflow prevention assemblies protect the public water supply from contamination. A failed or untested device is a hidden risk, one that regulators check during sanitary surveys and CCCP audits.
California requires backflow prevention assemblies to be tested at least annually by a certified tester, with reports kept on file.

What a certified test covers
A certified tester evaluates the assembly's components, check valves, relief valves, and test cocks, under flow and no-flow conditions to confirm it operates correctly.
Post-repair testing is required after any repair or replacement to confirm the device is back in service properly.
Air-gap inspections
Air gaps are a physical separation between the water supply and a potential contamination source. Inspections confirm the gap meets code requirements and is documented in your program records.
The records regulators expect
Assembly ID, location, and type for every device.
Test date, tester certification, results, and any repairs.
A schedule that proves annual testing is current, not a folder of one-time reports.
When incidents happen
If a backflow incident occurs, you need investigation, notification, and reporting support on the required timeline. Exodus provides 24/7 incident response as contracted.
