Ask Me Help Desk - Under kitchen sink

Under kitchen sink

I have a 50 year old home. Under the kitchen sink there is a 1.25" pipe that is stubbed out about 2" or so for the drain connection. It has a flange around the pipe at the wall. The flange looks to be made of lead and appears to a part of the pipe. The pipe has now rusted away on the bottom portion of the pipe. The top half of the pipe is still solid but the pipe wall thins as the pipe wall nears the rusted out portion. Unfortunated, the portion missing is all the way back to the flange so there is not enough "stub" all the way around to attach to. I know this is not uncommon on older homes but have never seen one fixed. What are the options on repair? Thanks in advance.

I am having trouble figuring out how to get a picture posted any ideas. Sorry, I am new to using threads.

The first picture is from the top showing a better view of the "lead" flange. The second shows more of the bottom where it has rusted away. A rubber collar just allows water to leak out between the rubber and the flange because there is no pipe for the rubber to cover on bottom.

OK! Awesome... the picture helps tons! Now that you know how to post a picture, open up the wall around the lead flange there a bit and let us see what is behind the wall.

It is what is behind the wall that will determine exactly how you will fix this issue, OK?

Ok, I really appreciate your help and your quick responses. This is a house my son is moving into and is about 30 miles from me so it may be a day or two before I can get pictures, but will get back to you for sure. Thanks again.

Don't be afraid to open the wall. There is no way of repairing or connecting a drain without opening up the wall.

I swear I thought the same thing when I said, "a bit", Harold. Good idea to emphasize the fact the these guys have work to do if they want to do this themselves and it starts by opening up that wall a little more than A BIT!

Thanks!

Hey, thanks for the help. I figured where this going to go, either I was going to be cutting off a pipe or trying to unscrew a 50 year old joint while hoping I don't screw up any other plumbing in the process. So, I decided to go another route from my redneck background. I made sure the rest of the pipe from the wall to the tee was solid and not rusted through and then I took a rubber connection collar, applied a bead of neoprene rubberized roofing compound around the pipe at the flange. Pushed the collar into the rubber and tighten the clamp and then put an additional bead around the end where the rubber met the flange. Everything is water tight and working well. The compound is supposed to last 30 years which is probably longer than the house will.

Thank you for your time and willingness to help. I know this was not particularly the "best" fix but it was a fix that met my time and abilities, (and budget).

Great ingenuity to solve a common problem with older houses. You are lucky in that there is no pressure, except for drain water, on the fitting. Let us know in 30 years-no wait, I'll be 102 and hopefully fixing things in heaven, maybe even with Mark and Harold!

Congratulations, nothing I admire more than ingenuity.
