A. The building inspector, in reviewing building plans and inspecting plumbing as it is installed, shall prevent cross connections from being designed and built. Where the review of building plans suggests or detects the potential for a cross connection being made an integral part of the plumbing system, the building inspector shall require such cross connections be either eliminated or provided with an approved backflow prevention assembly in accordance with the applicable codes.
B. The building inspector's authority to review and specify shall begin at the point of service (the downstream side of the meter) and carry throughout the entire length of the customer's water system. The building inspector shall inquire about the intended use of water at any point where it is suspected that a cross connection might be made or where one is actually called for by the plans. When such a cross connection is discovered, it shall be mandatory that a suitable, approved backflow prevention assembly be required by the plans and be properly installed, in accordance with the applicable codes.
