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
Chip out the putty and any grout that's in the way.
If you can find a 1/2" drive deep socket (automotive) that
will fit over the stem, use that. If the stem goes thru
the drive hole, put a big pipe wrench on the outside of the socket.
Torque away.....assuming that the piping or other supports will take it.
I've had a couple that were in so tight that I had to remove the
whole valve body from the wall and take to the shop:-(
