Over all system check. After running through the system in zone one she had 3 heads with next to the street with high efficiency nozzles on a zone with rotary heads and two heads with MP nozzles. We swapped out the three nozzles to get better match precipitation rate. Same with zone three we swapped out seven high-efficiency nozzles to MP rotator nozzles. In zone four we replaced one rotary head that was leaking and change to high efficiency nozzles to MP rotator nozzles.
