Thanks for the response, Alex.
I checked out the controller box and yes, there is an "MV" connection with a wire going to it. I'm guessing that means I do have a master valve.
As these zones (1 and 2) have always shut off in the past, I'm confident that that's the way the system should work.
I'm a good student but hardly an informed one when it comes to this stuff and appreciate your help. The valve you feel may be stuck is the master or the one in the ground with the solenoid attached? Where would the master valve be located?
I've never had a valve apart and would really like to hear someone promise me that unscrewing a solenoid and putting in a new one would solve the problem but if I've got to dig further...well, I've got the time and inclination if you are willing to put up with my lack of familiarity.
Thanks!
Bob
