 (d)  Backflow prevention device: when required. A plumbing system shall be installed to preclude backflow of a solid, liquid or gas contaminant into the water supply system at each point of use at the food facility, including on a hose bib if a hose is attached, or on a hose bib if a hose is not attached but can be attached, by an approved backflow prevention device as specified in §  46.822(d) (relating to design, construction and installation of plumbing systems).

 (e)  Backflow prevention device on carbonators. If not provided with an air gap as specified in §  46.822(c), a double check valve with an intermediate vent preceded by a screen of not less than 100 mesh to 25.4mm (100 mesh to 1 inch) shall be installed upstream from a carbonating device and downstream from any copper in the water supply line. A single or double check valve attached to the carbonator need not be of the vented type if an air gap or vented backflow prevention device has been otherwise provided.
