another zone 1 won't shut off


I have changed the irrigation valves 4 months ago because of leaks.
This is what I have installed.

Where my hand is the valve commands zone 1.

Everything has worked flawlessly since I replaced the valves but yesterday, i noticed that zone 1 was always on.

I have changed the solenoids from the other zones but same result
I have checked the cables but same result
I have disconnected the solenoid completely but the water still is on
I have unscrewed the 4 screws at the top so clean the valve but still the same.

My next move is to replace that valve with a new one, but the assembly is only 4 months old.

Wonder what is going on..

Thanks for your lights

I modified your link so it would work, mrfixit.

I know this is obvious and probably isn't it but is that tiny lever which activates the solenoid manually in the off position?

Maybe there's a hole in the diaphragm. Try swapping parts with the valve next to it.

I had to replace the valve because when I opened it, I found that the diaphragm was ripped apart (see pic)

Bad Diaphragm

I can't believe that a 4 month old valve would degrade like this that quickly.

thanks for your advice
