Customer called for zone 1 not working. During system check we found zone 1 to be a bad valve and found a few heads leaking. We suggested to customer to change a couple heads in the front jasmine to 12” heads to get over the jasmine but we will wait another time for them. We changed out leaking heads and bad valve along with adjusted pressure regulator. Pressure regulator may be on its way out but is working okay right now.
