Help! My sprinklers have a mind of their own...
Hi everyone. I have sprinklers with a mind of their own. I have 9 valves running using an Irritrol RD-900 controller. My sprinklers go on and off even when the controller is set to off. The control board looked fried (it kept showing weird things on the screen), so I replaced it with another RD-900. Unfortunately, that hasn't solved the problem. Our sprinklers keep coming on, even when the controller is set to off.
Any thoughts? Any help or advice would be greatly appreciated. If this isn't a DIY, how can I find a reputable irrigation specialist?
