Over all system check. Customer pointed out the area/head that was broken in zone 2. The 4in head was broken and we replaced it with a 6in PRS head with a rotator nozzle. After that was fixed we found another head that was broken in zone 2 and also replaced it with a 6in PRS head with rotator nozzle. In zone 5 we found and clogged nozzle and replaced it with a 12F. In zone 8 we found two head that were not popping up high enough to clear that grass so we replaced the two heads with 6in PRS heads. Last we found a leaking rotor head in zone 10 and replaced the rotor.
