My house built in 1939 has a lead sink drain and the old j-bend pipe has corroded through. I realize the easy fix is using a rubber sleeve and hose clamps, but this is a 1939 Kohler free standing sink, so the ugly rubber coupling and clamps are highly visible.
In addition, the already cut off j-bend pipe is about 1/3 full of lead solder from previous repair or original construction. So that isn’t good for flow which another reason I think it should be removed.
I know I can heat up the j-bend pipe enough to remove the pipe.
I was wondering if there was a non-solder method of installing the new j-bend pipe, such as hardening epoxy such as JB-Weld or other?

the flange is covering the joint so its impossible to tell how difficult it will be to make the kind of repair you want to make.
post another picture with the flange removed.

Packy - You mean the chrome wall finish flange? It is definitely removed.
bernabeu - didn’t see anything in your post.
I was able to use the search function and found an older post with a similar situation.
The two main options were to sweat in a new pipe or use an epoxy, with the downside of the epoxy being a permanent mess if one had to remove the pipe again.
My plan at this time is to see if I can find a bar of 40/60 solder here locally at a plumbing supply in Dallas.
Any other thoughts or ideas are greatly appreciated.

Remove the hardibacker and fernco inside the wall

My first thought was to cut out the old lead pipe and install a rubber tee.
The outside diameter of the lead pipe is about 1.4-1.5". The smallest rubber tee I can find is for a 1.5" pipe, thus the sealing surface opening diameter is quite a bit more so it would not work.
Do you know of a smaller tee?
Thank you for your help.

since you have to patch the wall...
open it up a little more
get the correct size fernco rubber coupling.
cut the lead carefully and accurately so when tou install the rubber coupling about 3/4 inch sticks out of the wall.
patch the wall and use a deep box flange to cover the end with the trap arm attached to it.

Packy, thanks. But there is no rubber tee small enough that I can find to fit the outside diameter of the lead pipe. it is only about 1.4 - 1.5". A 1.5" rubber tee from fernco or other has an inner pipe diameter of 1.5" thus the clamping surface diameter opening is way too large.
Or did you have another idea of parts?

If a tee is needed use a pvc tee and connect 2 fernco couplings, 1 above the tee and 1 below

I already had in my hand a 1-1/2" rubber tee and the 1-1/2" pvc converter to sink j-bend pipe. So I went to Home Depot and bought 1-1/4" to 1-1/2" rubber converters and created this tinker-toy arrangement.
All tight, firmed up in place.
My goal was to have nothing but chrome showing under the free standing sink in the remodeled bathroom. I do have a deep chrome box flange and it might just cover the PVC to Drain pipe adapter piece. It will be close.
Thanks again plumbers!
