Stay on the official compliance path

The utility page remains canonical. This tester surface should only help the user take the next step after the exact reporting and deadline path is clear.

  1. Confirm the property needs a certified backflow test.
  2. Use the official SF.gov tester list.
  3. Schedule the inspection or test with a certified company.
  4. Stay inside the utility's accepted reporting path.
