SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

Did you do any work on the valve that wont come on now? Like change the bonnet, ( top half of valve ). There are a few possible reasons why your valve wont come on. Check the wire connections. One wire might be broken without you knowing it. I have a few ideas but I'd like to know if you did any work to that valve first.

I have the same problem.

Sprinkler is always on in 1 zone.

I tried to change the solenoid, no help
I tried cleaning the upper part of the valve, still no use.
I tried buying a different Jar top valve and replace the top part of my sprinkler valve with the new valve attachments

Still, i have the zone 1 always water will be on, when i turn the water valve on.

Due to this i am not able to use the water system on a timer, i need to manually turn the water on and off.

Are you 100% sure you swapped out parts on the correct valve?

Is the zone a drip or a low flow zone?

What model valve is it?

Take the valve back apart and make sure everything's in there. Is there a spring? A seat guide?

Turn the flow control down lower and see if it shuts off.

I doubt this is it because you fiddled with the wiring but does the valve shut off when you disconnect the wire?

If you can't figure It and it's the correct valve maybe reassemble the valve you bought and install it.
