Valve Won't Shut Off

First, I have been reading this forum for a while and appreciate all the great advice you experts have given.

Now, my problem. When I started up my system for spring, the final zone (Zone 5) will only work manually (turning the valve on or off by hand in the valve box). The other 4 zones work perfectly. Thus, Zone 5 is either always on or always off.

What I think is the problem: While tinkering with the valve for Zone 5 (this is my first spring to have a sprinkler system), I turned the valve knob past "off" to the point it came loose. When I screwed it back on, it tightened to the off position as normal, but a single black wire appears to have been ripped loose from its connection. The black wire that is loose is connected inside the valve knob.

I believe this now-broken connection opened/closed Zone 5 from the controller. This would explain why it will not work other than manually. Tonight, I will try to splice the broken wiring together with a connector and see if it works. If not, I assume I may have to replace the valve.

I appreciate any thoughts or advice from others who may have encountered this problem.

I believe you are referring to the wire coming out of the solenoid. There should be two wires coming out of the solenoid (or valve handle). One connects to the zone wire coming from the controller, and the other connects to the common wire (usually white) which runs to all other valves. This is a simple fix, and you should not need to replace the valve. Simply get a waterproof direct burial connector (such as SnapLock or DryConn) and connect the two wires back together. That should fix your problem. Good Luck

Just to follow up:

I connected the severed solenoid wire with a DryConn wire connector (from Lowe's FYI) and it works perfectly. Thanks again for the tip.
