station won't shut off

[cmur]

I have a 4 station sprinkler system. The 4th station won't turn off after being activated by the timer. I replaced the cellenoid, but it still won't shut off even in manual mode. The only way to stop it is to turn off the main. Any thoughts?

Your diaphragm is bad or the ports in the valve are clogged.

I just installed 5 brand new anti-siphon valves, however, similarly one triggered via the timer, but it doesn't want to turn off.

How does one go about cleaning the ports in the valve ? as I can't imagine the diaphram being bad since the valve is brand-new.

Thanks

If your wiring is okay and the valve still isn't working properly, then why don't you just exchange it for a new one if you just bought it.
