Sprinkler Zone Problem
I have a new Rainbird system. When first installed all the zones (6 total) worked fine. The contractor came out to install one power control switch that he didn't have before and now my last two zones won't come on like before. I got them to run by messing with the zone valves in the control box for their area. But now it's either 5 or 6 but not both at the proper time. Any ideas on how to make the proper setting for those valves? Or do you think I might have another problem? Any help appreciated!
