Had my sprinkler guy out over the weekend as he was to winterize my irrigation system. There was a light freeze overnight (31 degrees) - our first of the year - and the guy was out very early in the morning. The copper piping out the side of my house needed to be heated briefly with a blow torch to get the water flowing. The plastic PVC pipe on the other side of the valves was also heated but I could not get water to flow to the sprinkler heads when a manual run was chosen on any of my zones. The forecasted high for the day was to be 36 degrees so he said he would stop out later in the day to try again. At 4pm the temp was 36 degrees and any and all ice/condensation from the early morning was long gone. Still was unable to get water to come out of the sprinkler heads.
In short my system states it is online but I cannot get the manual start of an individual zone to work. Any suggestions?
