Customer called us out stating he having the same issue with zones 4-5. However last time we whore here every zone was working and ohming out. We back tracked our work and even did new connections at the valves leading to zones 4,5. This didn’t change anything, we investigated for another 30 minutes trying to look for a cut in the common and power wire. We were un successful in finding the break. In order to fix this issue he will need to run new wire to these stations. There are 2 valves on both sides of the valves not working, yet these valves are working fine and show no signs of bad wire or connections. In total the wire would be a 3 strand multistrand wire and roughy 170ft. I have verified that this issue is not related to the work preformed.
