tub drain removal - Arrrrgh!

homeboundFebruary 25, 2010

I'm dealing with a rusty tub drain circa 1947 in a cast iron tub that was recently refinished. I need to either replace the drain flange (from above) or de-rust and coat it with something to make it shine again. I tried to remove it with a dumbbell (the drain tool for this), but this thing is seized. I even tried to lever it off with the dumbbell and a wrench and hammer, but to no avail.

Any ideas? If I can't get it off, any other options? Can I hit it with naval jelly and coat it with something? Thanks.

Time to just live with it.

If you have a lever operated waste and overflow, remove this mechanism.
Using a dremel or similar cutting device, I use a sawzall, carefually cut the drain and threads in two places about 1/2" apart. With a screwdriver, pry this section out. When this is done, collapse the remaining section and remove.

We're living parallel lives! I posted the same problem last month at the link below. I found out that there is a wrench that will do it, but there was some concern that it might disturb the old plumbing in the walls. I was then told that it could be cut out as mentioned above. The guy at the plumbing supply place kept repeating,"just don't cut into the tub", which didn't do wonders to inspire confidence. I dried it off really well, masked the area, applied some chrome paint, and bought the Flip-it tub stopper(which only leaves a narrow rim showing around the outermost edge).

Except for being taken out when I clean the bathtub, it now lives in that drain forever!

Good luck with yours!
