Tub Drain Removal, PLEASE help
Hello! I am desperately trying to help my mom replace her tub drain and the surrounding pipes. I'm usually okay with these things and learn quickly through videos, but her house is from the 70's and had a ribbed brass overflow drain pipe setup thing as well as this brass piece underneath. I cannot for the life of me separate the drain from this piece. They both seem to loosen in the same direction, and they just keep spinning.
I got her to hold pliers so the drain would stay in place while I try to twist this off, but it didn't work. I don't know that there's enough space for me to get any kind of saw in the small space to try and safely saw between the under side of the tub and the drain. (Both because there isn't room in the space where the wood is cut out under the tub (basement ceiling) and because I can't loosen it enough to fit a saw above this brass piece/under the tub.) I am way out of my depth. I've PB blasted the heck out of both sides, used a hair drier to try to loosen the old putty, hammered the sides and underneath (hence all the dents), used a drain remover tool, etc. I just need both pieces out to I can finish the job as it was leaking and broken. Any help is appreciated more than you can imagine. Thank you!!!
