I'm trying to remove a pair of pfister shower valves. I've removed the handles and flanges (or whatever the right word is) and now I'm down to removing the valves. I cleaned up with Naval Jelly then soaked with WD-40. One is surrounded with plumbers putty and turns a half a revolution or so then binds. The other one has no putty around it and won't budge with probably 50 ft-lbs torque.
Anybody know how much force is too much? Or any tricks? I hear mineral spirits or turpentine are good for softening old plumbers putty. For the other one should I use more WD40, Naval Jelly or what??
Thanks BC
