Is there a smaller size that's standard? I pulled out a broken bathtub drain insert because it was broken, and the standard 1-1/2 inch size does not fit. Is there another standard size that fits maybe older homes? The house was built in 2002, but it looks to be a pretty standard shower/tub insert.
The thing is the 1-1/2 inch tub stopper DOES fit through the hole in the tub but not in the actual pipe below (it's too big to thread in). Any ideas?
