sprinkler valves problem: bad diaphragm
I have a problem with my sprinkler valves (orbit). These have been installed a few years back and worked fine. Now, the irrigation system starts early in the morning so I cannot tell when the problem really started.
We extended one irrigation line and added an additional sprinkler head and removed one to compensate. Now, when turning on that particular station/valve manually or electronically, I hear the water flowing, but no water is coming out from the sprinklers.
To make this particular line work, I need to turn on one of the other two lines simultaneously with the one that doesn't(the one that doesn't work and one that works). This trick works with either combination of the 'working' lines with the one that doesn't work if turned on individually.
Once I tricked the system, the water is coming out all right from the line that causes problems. However, the next time I want to activate it again, I have to use the same trick again.
I am wondering if I have to take the valve apart or if the sprinkler line is too long. Any help is greatly appreciated.
Thanks!
