(a) An approved backflow prevention device shall be required on each water service branch serving premises where the following conditions exist:
(1) The premises have an auxiliary water supply, unless such auxiliary supply is accepted as an additional source by the water purveyor and the source is approved by the County Department of Health.
(2) A substance is handled on the premises in such a fashion as to create an actual or potential hazard to the public potable water system. This shall include premises having sources or systems containing process fluids or waters originating from the public potable water system that are no longer under the sanitary control of the water purveyor.
(3) The premises have internal cross-connections that, in the judgment of the water purveyor, are not correctable, or intricate plumbing arrangements that make it impractical to determine whether or not cross-connections exist.
