Frequently asked questions
How often is backflow testing required in Trabuco Canyon?
In Trabuco Canyon, backflow prevention assemblies are typically required to be tested and certified annually by a licensed backflow tester.

If your backflow device fails its annual test, it will need to be repaired or replaced by a certified technician, and then retested to ensure it is functioning correctly and in compliance with Trabuco Canyon regulations.
Do I need a backflow preventer for my irrigation system in Trabuco Canyon?
