After the system check we found 1 pipe leak in front yard 1 drip leak in flowerbed 2 low heads on front right side 3 heads to be replaced per customer 1 leaking rotor in backyard 2 broken nozzles We found that the tree bubblers are running on the same zone as the front yard spray heads we recommend splitting up that zone making the bubblers its own zone because it is the wrong application and the trees are being overwatered while the spray zone runs.
