Information to gather
- Property and assembly address.
- Water authority or district name.
- Assembly type, size and serial number when shown.
- Testing due date and reporting instructions.
- Any known leak, damage or recent repair.
What testing determines
- A certified test evaluates whether the assembly is operating within required performance limits. If it does not pass, the tester can explain whether repair, retesting or replacement is appropriate.
Use the correct authority resources
- Tester eligibility and reporting procedures can vary. Scylla links to official San Diego-area district resources on its backflow service page and can help identify the correct jurisdiction.
