What to check for Frisco
Use this page when the assembly already failed and the next step is repair, retest, and accepted report submission.
- Due basis: Certain backflow prevention assemblies with test ports must be tested upon installation and thereafter annually by a licensed backflow tester. Frisco administers annual inspection fees through BSI.
- Who is affected: Properties where the hazard review requires a testable backflow assembly, including irrigation-related installations and other inspected hazards.
