PGV 1"

Mr. Fixit,
Thanks for all your feedback!
It supplies a 1/2" drip line with pressure reducer, however the tubing has many leaks right now.
I'm trying to fix the valve first.
I'll go back and try venting the air like you said.

Yeah strange. Do you turn on the valve with the bleeder screw to get the air out of the valve after the repair? Trapped air can cause a seepage.
I'm not a big fan of that valve so I try to not install them. But I can't recall having the seeping problem. I did forget to put the white seat guide in once. Oops! The valve stuck on because of it a couple of days later.
I'm assuming the solenoid is snug clockwise.
Maybe take some fine sandpaper to clean up the seat a bit.
Could be hairline cracks that you're not seeing. Use a flashlight and squint. lol
Long ago I ran across a couple of old Irritrol controllers in the metal cabinet that would cause a seepage by sending a constant current to the valve. I installed the new valve entirely, still had the seepage. Installed a new controller, the seepage stopped.
It's not on a drip line is it? Sometimes that'll do it too. There's not enough flow going through the valve to shut it off all the way. Turn the flow control down a bit.

Hunter PGV 1 inch in-line - Won't shutoff completely

I've been repairing/replacing several of these PGV 1" valves (square top) lately.
When valve is leaking - thru all the time, I replace just the top half (if body and seat looks good).
My problem is, about half the time I do this, the valve still leaks thru the seat.

I am very careful the rubber diaphram is lined up properly with solenoid, but still no joy.
Any ideas?
