How do I know if my Irrigation system requires an RPZ Backflow Prevention Device?

If you have a permanent, in-ground irrigation system connected to the City Municipal Water Supply, you have to have a Backflow Prevention Device. If you have disconnected your permanent, in-ground irrigation system from the City Municipal Water Supply and are only using Well Water or Auxiliary Water, then an RPZ Backflow Prevention Device is not needed. If you have connected your Well Water or Auxiliary Water source to your irrigation system, and it is still connected to the City Municipal Water Supply, then you will need an RPZ Backflow Prevention Device. If you are running a temporary, movable irrigation system not connected to the City Municipal Water Supply, then you do not need an RPZ Back Flow Prevention Device.
