Annual testing for properties in the City’s jurisdiction.
The City of San Diego Public Utilities Department says all backflow devices in its jurisdiction must be tested annually. If the property is served by another water provider, follow the due date and submission instructions on that provider’s notice.

The notice helps identify the responsible water authority, assembly and deadline. Scylla can confirm the appropriate testing and reporting next step for the property.
Three steps from notice to documented result.
Water providers set their own tester requirements, due dates and reporting methods. The notice and service address help confirm which instructions apply before scheduling.
Match the property address, deadline and assembly details on the notice. Water providers can use different schedules, approved-tester lists and reporting systems.
Scylla tests the assembly and explains the result. A failed result does not, by itself, determine whether repair or replacement is the better next step.
If repair is needed, review the repair and retest options. Follow the provider’s report instructions and due date, and keep a copy of the completed test record.
