        Sprinkler system issue Sign In/Join 
        posted
        We have 7 zones programmed into our sprinkler system. Each zone used to run just like it was supposed to...one zone at a time. But now Zone 1 continues to run when any other zone is running, giving the lawn in Zone 1 territory too much watering and cutting down on the water pressure for the sprinklers in the other zones. We tried replacing our old programming station with a new one, but it still does it. Any suggestions?

        sounds like your zone one manifold valve is stuck in the open position. check your wiring to see if it's damaged and not sending a signal to close. , or, maybe you have a piece of something stuck in the valve holding it open

        You should have a box in the ground that opens up. There are valves in there. If you manually fire each zone one at a time, you should hear that the valves open and close. I agree, zone one is sticking. It could also be a loose wire or a bad diaphragm.

        Thanks! I will check on that this weekend. If the valve is stuck in the open position, what would be the fix for that? A new valve? Could I get that at Home Depot or somewhere such as that?

        Yes, new valves available at Home Depot or Lowes or Ace, check your wire connections at each valve too, maybe some are touching each other and should not be.

        chances are you dont need a new valve, probably the problem is with the solenoid that operates the valve. find the manufacturer of the valve, go to their web site, and get a breakdown of the valve along with instructions on trouble shooting it, then get the defective part. If the problem is with a piece of junk stuck in the valve, it should be easy to clean it out
