I'm trying to get a leaking drain out of a cast iron tub to re-seal it. I saw the thread posted here a while back on how to remove it, but mine apparently is not the same kind. There is nothing inside to grip so I bought a tool called a "drain out" at Menards. I think it will work, but for the life of me I cannot get it to break loose. I'm using a 14" wrench on the thing! Its hard to get leverage inside that space.
Should I try a little heat from below? The tub is on the first floor so I have access to the under side of it. Is there another way to remove these kind of drains?
I don't want to replace it. It works fine. It has a slow drip I would like to stop.
