If I have multiple backflows on a property, do I need to test all of them?

Backflow Prevention
It is mandatory to test the backflow assemblies that contain the water distribution system ex. Main Domestic, Fire, Irrigation annually.
Everything beyond the containment are considered isolation assemblies and are only recommended for annual testing.
