I'd like advice on how to remove a tub/shower drain stopper, please. My tub is old and the drain is clogging. I removed the hair, etc from the drain at the bottom of the tub and it has not helped the rate of water drainage. I've read that I should remove the overflow plate and remove the drain stopper. I've tried that but I can't pull the drain stopper out. It feels stuck. How can I remove it?
Thank you.
