Official San Francisco certified backflow tester entry
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.

San Francisco is a strong approved-tester utility because SF.gov publishes a genuine certified tester list with contact details.
This provider is most tightly associated with San Francisco Public Utilities Commission Backflow Prevention Program. 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.
