I just moved into a new house. The front set of sprinklers all work fine. The rear set (3 valves) are not. The controller seems to be functioning properly.
I tried the manual bleed screw on all 3 valves. Some water comes out but there doesn't seem to be any pressure. I'm guessing there should be pressure here as when I do the same thing on the front set, the sprinkler turn on.
The rear plumbing setup is like this. Metal pipe is coming out of the house and goes direct to a garden hose. Below the hose, the metal pipe continues to a shut off valve. The other side of the shut off vale is PVC and goes to the set of sprinkler valves that aren't working.
The garden hose is working fine and has good pressure.
I think there might be something wrong with the shut off valve although the guy at the hardware store said these things rarely fail. I tried turning the shut off valve and it turns maybe 1 to 1 and a half revolutions which seems odd.
Is there a way I can verify this is the problem? And if it is, how do I replace it? I tried taking a pipe wrench to it and it looks like the PVC is cemented to the shutoff valve. Do I have to hacksaw it off?
