I was caulking my bathtub and was removing the caulk around the overflow plate when the linkage for the plunger came loose. I removed the linkage put the plunger back down the hole but now then the tub wouldn't hold water even when though I could hear the plunger bottom out.
I took the overflow pipe off and discovered that there is a lip on the pipe that the plunger is bottoming out on and I can't get the plunger past this point. I included a pic of where the plunger is bottoming out on the pipe. I cleaned up the lip with a wire brush and file and greased the plug with plumber's grease and still no luck. I bought a new plastic plug and was able to get it past the lip but broke it in the process.
