I'm trying to replace a Price Pfister single handle (avante?) shower valve.
I've unscrewed the chrome nut that is on the outside, leaving what I believe to be a washer surrounding the valve stem. But just pulling forward on the valve (even with the handle fixed on) doesn't seem to budge or show any movement.
I've tried prying behind what I think is the washer on the outside, but because of the setback, I can't get anything behind it.
Do I just need to pry that washer out of there with something, or is there anything more to do before the cartridge will release?
