We have a bathtub with a hidden stopper (Price Pfister), the sort where you just flip a lever up or down to close the drain, but the actually stopper mechanism is hidden inside. Recently, it has started draining slowly, so we did the usual plunger routine - no help, and then the snake routine. I discovered after removing the internal stopper that the drain started working again. However, I can't find any sign of a clog around the area where I think the stopper would be sitting.
So here's the question. Why would this happen, and how can I fix it? I'm considering just tightening the turnbuckle so that the stopper doesn't go as far down, and that may well work, but it doesn't explain why things changed - unless it's possible for the turnbuckle to just loosen over time. And, of course, I can always leave the stopper out, and use an oldfashioned rubber drain cover for the rare times we need to fill the tub.
Many thanks,
Gary
