Okay folks, first of all let me lay it down: 1. I am not handy whatsoever 2. Excuse my tub stopper- the finish is horrible I have been trying to get this twist and pull stopper out for a few hours, and I can't get it. It's approximately 16 years old, and I hardly know what I'm doing. No, it does not have a set screw. Yes, I have tried two sets of pliers together to try to loosen the top. I think it is now broken, as it doesn't twist and stay open. Help me.
