Irrigation and Pressure Vacuum Breakers

Irrigation and Pressure Vacuum Breakers

Irrigation and Pressure Vacuum Breakers

Pressure vacuum breakers that are currently being used for backflow prevention on dedicated irrigation lines are acceptable as long as the assembly passes annual tests. City of Boulder Design and Construction Standards 5.09(c)(4) states:

Reduced Pressure Assembly Required: All irrigation systems with a separate, metered service line shall have a reduced pressure principle assembly installed in compliance with all applicable city regulations and standards.

Therefore, if a pressure vaccum breaker fails and requires replacement it should be replaced with a Reduced Pressure Zone Assembly.
