Valve problem?

I have a front yard with 3 stations. The problem we are having is that the first station in line comes on when the water is turned on. I have replaced the control valve with the same result. The power to the station timer is off so I don't think it is electrical. Any ideas would be appreciated.

Make sure that the bleeder screw is all the way closed. Sounds funny but I replaced a complete 2" brass valve at a school to find out that the bleeder was not all the way seated. Oh,, the valve was 3' in a hole just big enough for my buck 50 azz to fit in the 3 valve boxes stacked together. Make sure the soelnoid plunger is not stuck and moves freely. Sometimes they get rusted and hang up. You said that you have replaced the valve?? so most of the parts have been replaced if you did not cut out the valve from the line. Check to see if the diaphragm is seated properly and the oring is in place . Some valves have a small oring also. If it is not connected to the controller and still leaks when turned on maybe the diaphragm has a worn spot if you did not replace it also. If that does not fix it. Then it may have a crack in the base of the valve, not broke internal parts. If that is the case then you get to cut one out and replace the whole thing, sometimes this is better to do then replace parts because you have spent a great deal of time on one valve. Also make sure that it is the valve that is leaking, not one near it. You would not believe how many homeowners have told me that that is the one leaking and after listening to it with a mechanics stethescope it turns out to be a different valve then the one first thought. I am not trying to talk down to you, just have to list all my check-offs to give good advice and I am not sure excactly what you have done already. Hope this helps

Check to see if the inflow is not the outflow or the out flow is the inflow. Otherwise, as HBFOXJr said, check to see if the valve is installed correctly. Also, after checking if installed properly I would:
Check to see if anything got under the manifold of valve
Solenoid is not missing an "o" ring
Timer is not set to manual on that one station.

Is the power truly off to the timer or is the timer just on rain? If it is just on rain, could be the board of the timer. I have seen the board go bad and send power to a zone constantly. anyone else see this?

otherwise, I am betting backwards as well. Or missing spring?

Oh yeah. The old valve in backwards trick. Spent an hour last week before I realized it was backwards. Homeowner said he replaced the valve, but I assumed just the top, diaphragm and solenoid. I tried new diaphragms and solenoids 3 times. Finally dug the whole thing up and realized the prioblem. Wasted time. But, I still charged him. Even though I got paid, I hate when I waste time, or someone else wastes my time.

I'm with HBFoxJr.


also..


If you are worried about it being a bad station, use another one if it is available. If that does not help then you know it is not the timer.

I almost 100% guarantee this is the valve.

Valve problem solution.

Ok, I have the dunce hat on. The problem was that I was fixing the wrong control valve. The home owner assured me that it was the far left valve in the sequence. It turns out that it was another valve in the line. After further inspection, it was found that the middle valve was the problem. Replacing it solved the problem. It was my fault for not checking it further on my own.

Thanks to all for the the replys and suggestions.
