(A) The City and County Inspections Departments have the responsibility to not only review building plans and inspect plumbing as it is installed; they also have the explicit responsibility of preventing cross connections from being designed and built into the plumbing system within its jurisdiction. Where the review of building plans suggests or detects the potential for cross connections being made an integral part of the plumbing system, the plumbing inspector has the responsibility, under the North Carolina Building Code, for requiring that such cross connections be either eliminated or provided with approved backflow prevention equipment.
(B) The Plumbing Inspector's responsibility begins at the point of delivery, downstream of the primary containment backflow prevention assembly, and continues throughout the entire length of the customer's water system. The Plan Inspector should 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 is discovered, it shall be mandatory that a suitable isolation backflow prevention assembly, approved by North Carolina Building Code, be required by plans and be properly installed.
