Thanks for the tip, it proved helpful. Yes they are the same 2 zones always (7 and 10). When I disconnect 7 they both go on when 10 is on and when I disconnect 10, they both go on when 7 is on. I haven't done any digging recently, but I did notice some chipmonk holes (I hate those darn things) very near one of the valve boxes. Have you ever heard of them chewing the wiring?
I am new here so I apologize if this is the wrong forum, but I'm curious if anyone knows what I should try to fix the following problem: I have a 4 year old system with 10 zones. Starting a few weeks ago 2 zones go on simutaneously when operated by the controller. When I turn the valves on manually at the valve box they work perfectly. The 2 valves in question are located in different valve boxes but when I inspect the wiring on each everything looks fine. Any ideas what may be the problem? Than...
