Backflow Prevention devices help to protect the City water system from pollution and contamination by providing a layer of protection at connection points to private water lines. The Prescott City Code Title II, Section 2-1-5 grants legal authority for the Cross Connection Control Program, with the adoption of the International Plumbing Code; City Code Title III, Chapter 6, Section 608, in compliance with Arizona Administrative Code R18-4-215.

The type of backflow prevention device required is dependent on the degree of hazard present. Each device must be installed according to manufacturer’s recommendations, Prescott City Code, State and Federal Regulations. A backflow device must be tested by a certified backflow tester following repairs or installation, and then annually thereafter. The City requires all testers to submit their certified test reports to the City’s Water Protection staff. All reports must remain on file for three years, pursuant to ADEQ regulations, for all backflow prevention devices within the public water system.
