Customer called because 3 of the 6 zones were not working. When we arrived we found zone 1, 3 and 4 had bad valves. We located all the valves and replaced. Zones 3 and 4 valves were under the deck so we had to pull the deck boards up to get to the valves. Once they were replaced we found we also had a wire issue and ended up running a 3 strand wire around the deck and under to the valves. We then checked system and replaced a rotor and a few heads. We also repaired a few pipe breaks.
