I know some of you will get a chuckle from this question, but how do you remove the control knob from a Price Pfister three knob shower valve? I've removed the center screw and when I grasp the knob, the valve still turns/pulls/shakes. Do I need a special pry-off tool?
Thanks!

"Do I need a special pry-off tool?"
You do. It's called a "handle puller",(see image) and it works just like a wheel puller. Most plumbing wholesale houses carry them. Good luck, Tom

Thanks Tom. That's the picture I had in my head, just hoping I didn't need to buy one. Oh well. I thank you and the others on this forum for your previous posts. Without them I wouldn't know what my original problem was or how to fix it. :D
