We've been in our house for a year now and the system has been working fine this whole time. I do have a couple heads that I'm repairing/working on right now. But, the issue right now is that the water won't come on at all. I've checked the programming on the box (Irritrol system) and tried to turn on specific zones. Nothing is working. I looked through the manuals' trouble shooting, but nothing seemed to apply. However...I'm a rookie at this. Any thought would be appreciated! Kim
