This is DIY bathroom re-do job. The drain pipe from the shower has rusted and broke off at the "y" branch arrow "B". It will be replaced with PVC. The yellow line is the bathroom sink drain...and I've cut that pipe off at the yellow line. It is going to be replaced with PVC as well. I want to remove the Y-branch.
I figure that I'll use one of these rubber couplers slipped around the hub at "A" to adapt to the new PVC from thre sink and shower.
So here is the problem. I cannot get the "Y" branch out of the hub at "A". I do not have any experience with this hardware...but I figured it would wiggle out with some muscle. I don't have enough muscle to do it.....even with the mutha-of-all-breaker-bars on the end of a pipe wrench...it won't budge. It's a tight fit under the house and not much room to work.
