I'm in process of building a system and want to do it so as to not break any codes pertaining to the Pressure vacuum breaker. My property has a large elevation change and the top of the lawn will need several sprinkler heads that will likely end up 8-10 ft above the grade of the water feed/valves. Code states that the PVB needs to be 12 inches above the highest head. How can I achieve this without a 11ft tall pvc pipe loop for the PVB?
light blue is well/water tap where the sprinkler valves and controller will be
dark blue is planned heads for irrigation to lawn and they sit roughly 8-10 ft uphill
