one valve will not actuate or manually open.

I replaced all valves in a 7 valve series. I have a functional rainbird commercial controller. I troubleshooted the new valve extensively, 24V at the solenoid. I replaced the entire valve with a jartop and repeated the troubleshooting steps. Still will not open. could there be an obstruction within the outflow causing this. What are your thoughts? How do you recommend further testing.

I can come up with a few ideas.

I'd take the valve apart and make sure all the ports are clear. Could be glue from the new install.

Move the wires from a valve that works to the one that doesn't.

I suppose you could cut the pipe open to see if water gushes out. That would determine a clogged pipe. Poly pipe perhaps?

If it's an anti-syphon valve simply take off the cap. I ran across a valve that was doing the identical thing you're describing. I took the cap off. Water gushed out and the valve was fine after that. It was stuck somehow. It's still working today. This was on a dripline.

New valve installed backwards?

Flow control not open?

Maybe the valve is indeed coming on and there's a broken pipe giving the impression it's not working.

Let us know what you find. I'm curious.
