Pro-c problem

We have 10 zones setup and after having system off for a few days due to rain the system is now running zones 3 and 8 all the time when any other zone is one. I have tried a run thru all zones with the ground disconnected and that does not seem to have fixed it as i would assume if that was going to work as you passed thru the #3 vlave to #4 that the #4 would have shut off properly. Thanks for any help

You may have valves that are physically stuck open. Sometimes you can get them to close by opening the master valve only, with none of the zones energized.
