Need to get back under there and see if lossening and snugging the WG to WG flange improves anything. I had tested it on the bench before the stud work and the valve did suck open at around 17psi
Maybe a piece of metal filing?
Seriously, I hope it is the valve not seating and not a ruptured diaphragm.
