The recommended backflow assembly type is a Reduced Pressure Zone assembly (RPZ). A backflow assembly is needed anytime culinary water will or may be used for irrigation. If using culinary only for irrigation, the backflow assembly must be installed on the main sprinkler feed line before the tee, junction, or the first set of control valves. If you are using culinary and secondary, the backflow assembly must be installed before the swing-line box. A backflow assembly is not required if secondary will be the only supply for your irrigation system. Backflow assemblies must be tested by a certified backflow technician within 10 days of initial use and annually thereafter.
Safe Drinking Water Act of 1974, Public Law 93-523, Water purveyors are responsible for the quality of drinking water delivered. This required that contamination from backflow be eliminated.
Utah Code, Section 19-4-112 states “there shall be no cross connection between the potable (drinking water) and non-potable (auxiliary water) systems”.
Unprotected cross-connection that may affect water quality, are not allowed. Approved backflow prevention assemblies must be used.
Backflow assemblies must be tested on an annual basis by a certified tester.
Drinking water systems shall be protected for cross-connection from an pressurized irrigation system.
Requires annual testing on all backflow assemblies.
