Official IRWD backflow tester list entry from the district's convenience roster.
This profile does not override the utility's official rules. It exists to make the public provider layer inspectable after the governing workflow is clear.
The strongest local provider pages do not stop at a phone number. Confirm the authority source, the utility's tester gate, the report route, and the proof trail before you schedule or send a failed device back for retest.

IRWD is a good California district page because it clearly explains when the district will require an assembly, what assembly types it recognizes, and where customers can find certified testers.
This provider is most tightly associated with Irvine Ranch Water District Backflow Prevention. Use that page to confirm the exact local rule before booking or routing a lead.
If a phone number, website, or approval source is wrong, report it for manual review. BackflowVerdict updates public provider profiles only after checking the source record.
