I'm trying to clean my sink's pop-up stopper.
I was able to remove the pivot rod nut with no problem. I removed the spring clip and clevis strap from the pivot rod.
But the pivot rod won't budge. When I look at videos, the pivot rod should slide out easily, and mine won't move at all. It unscrews, but after a long time of trying to unscrew it, I gave up. I can still hear it unscrewing but don't know what it's doing and nothing seems to change.
I tried grabbing pliers and yanking on it but it's in there tight.
