Zone not working - out of ideas
I have a zone that stopped working a few days ago. I have a standard anti-siphon valve set up with a disc filter and a pressure regulator after the valve (this is for the drip irrigation zone).
The testing that I have done so far are:
Tried turning the solenoid manually - does not work.
Tried turning the bleeder - does not work.
Taken off the valve completely - water comes through, so it is not a supply issue.
Taken off the top of the anti-siphon piece and turned the solenoid - water comes through the anti-siphon.
Taken off the disc filter cover and turned the solenoid - water comes through the filter opening.
Taken out the disc filter and reclosed the filter cover (to eliminate an issue with the filter) - sprinklers do not turn on.
The next step that I am about to do is to take off the pressure regulator to see if it is a problem with that, but in order to do that, I need to cut the pipe. Wanted to see if others have had this issue. Also, if it were a problem with the pressure regulator, would it not send water back put through the anti-siphon?
