moen knob
Maybe the way I described the problem was confusing. The knob has a lot of play when you try to turn it to adjust the water temp. The screw that goes through the center of the knob does not tighten or loosen it. I thought the screw was stripped, but it won't pull out either. Somebody told me to drill out the head of the screw, pull off the knob, and then get the screw out. I'm worried that I'll ruin the whole unit and cause myself a lot of money in unneccessary repairs if I do that. What do you think?
