I was trying to fix my bathtub plunger drain stopper (not sure if correct term) which was completely stuck and unmovable. I pulled it out and attempted to replace it at Home Depot with a pop-up drain. However, my drain is too small (and has too small a thread size) to fit the bushing, but too large (but correct thread size) to fit the drain without the bushing. The Home Depot employee (who was very knowledgable) was completely stumped and had never seen a drain this size before.
I am living in a condo that was gut renovated about 7 or 8 years ago, and I have no idea what size drain this is. I have no way to replace the drain pipe below the tub. I measure (from outside of threads to outside of threads of the drain I unscrewed) 1-11/16" size of the drain. Most all the other fixtures are Kohler, but I have a suspicion that this drain was not replaced in the rehab. It's an old bronze piece.
Can anyone point me towards the correct bushing for this type of drain?
Alternately, I cannot get the brass plunger to fit back in the overflow. It refuses to go far enough to stop water from draining, and I hear it hitting metal. Any ideas of how I can get the plunger to get back in? This would obviate replacing the drain with a pop-up type stopper.
Thanks in advance!
