- Cadence: Annually
- Due basis: Flagstaff requires annual testing for assemblies in the city program, sends courtesy notices when testing is due, and routes tester result submission through BSI Online or city compliance staff.
- Notice or device clue: Look for the CCN, account number, BSI record, device ID, or assembly serial from the reminder.
- Submission: Flagstaff backflow prevention page
- Acceptance rule: Report acceptance depends on using the named portal or online submission path; keep proof that the report was submitted.
- Cost signal: Testing is market-priced, but mountain-climate installation details can increase service complexity.
