We've been having trouble with our tub/shower in our apartment not draining. Our shower is the type that has the little lever on the overflow plate to open and close the drain. Yet it is not the pop-up style. The drain opening at the bottom of the tub is just a clear open pipe. Considering this I thought our shower is the plunger style where the drain lever moves a brass plunger at the bottom of the overflow pipe to close and open the drain.
However, when I unscrewed the overflow plate and pulled out the linkage assembly I instead saw a spring at the end rather then a brass plunger. Here's a photo.
Right now the whole spring linkage assembly pictured above is out of the tub and the tub is still not draining. Is there suppose to be a plunger at the end of this the may have broken off? I also tried pluging the overflow pipe with a wet rag and plunging the tub but that didn't seem to help either. I've also tried passing a ZipIt all the way down the drain pipe and overflow pipe and neither pulled out any clogs or seemed to hit anything
