Commercial Backflow Preventer Requirements in Prescott, Arizona


commercial backflow preventer

When a water account is established, the public water utility examines the backflow requirements for every organization. Businesses that provide a possible backflow danger must install and test the proper backflow prevention device every year.


To identify backflow threats, the public utility evaluates the type of company, how the firm uses water, and what appliances or equipment are connected to the building's water supply system.


Customers are asked to submit a Backflow Assessment Form to a certified backflow tester to provide further information about their water usage, which is one way to evaluate backflow hazards.

Why Do You Need a Backflow Preventer?

By adding an extra protection layer to private water lines at connection points, backflow prevention devices assist in protecting the city water system from contamination and pollution. With the implementation of the International Plumbing Code, Section 2-1-5 of the Prescott City Code Title II permits legal authorization in line with Arizona Administrative Code R18-4-215 for the Cross Connection Control Program; Section 608, Chapter 6, City Code Title III.


The specific kind of backflow device needed is determined by the level of risk. Each item must be placed following the manufacturer's instructions as well as Prescott City Code, Federal, and State regulations.


Following installation or repairs, a backflow prevention device needs to be evaluated by a trained backflow tester and then tested annually. All testers must submit the certified test report to the Water Protection Department of the city. According to ADEQ standards, all backflow devices inside public water systems must file reports for three years.
