Question
I have a zone on my lawn that continues to run when the other stations are turned on.  What could the problem be?

Answer
Hey Jim, normally the problem is in the valve itself, either the diaphragm needs replaced or the plunger in the solenoid is stuck and the solenoid needs replaced. Go to www.irrigationtutorials.com, and this website will show you how to rebuild the valve. It is not that hard, and you should be able to do it yourself. Good luck and have a great day.
