Sprinkler question
 

I have lawn genie valve on a RainBird clock. The valve can be operated with
the manual screw, and it will open and close. Sometimes. On the clock, it
will open and close. Sometimes. Other times, it stays at a state of
freeflow, even after the manual screw or timer has been turned off. I
changed the diaphragm, and found a snail shell inside. There was also other
various crud from our ag water supply. The filter goes in tomorrow. I
switched to another actuator, which I think is new. This is 36v, I'm
assuming AC. But I fried my tester last week, and haven't got a new one
yet. Ideas on diagnosing this? It's a PITA to remove because I have to dig
it up entirely to remove the valve, but this time, I shall install new valve
WITH union for future problems.

Any help appreciated. It's driving me nuts.

Every valve I've ever seen was 24 VAC.

Did you flush the line when you fixed the valve?
