I am trying to get the one working in our new place and it just won't cooperate! Here's the deal. The system was installed several years ago (woohoo for us!). I found out the controller box was bad so I replaced it with a spare one from our previous home (I know it's good). A couple of the heads were busted so I repaired the pipe and replaced the heads. The valves will work ONLY if you turn them on and off maually. The controller box has no effect on them. I know the valves are getting power (I used my multi-meter), so I think I need to replace all of them (there are 4). If that doesn't work, I am at a loss as to what else could be the problem /forums/images/icons/confused.gif Has anybody here had to deal with this? I would like to get them working so I can go back to being lazy except for when I am working on my blazer!
