Kitchen Drain Help

[Lorne]

Hello,I am not a plumber .... my kitchen drain was leaking where it ties into the cast stack. Looks like a weird job but was like that when I bought the place 12 years ago. Anyway,took the trap off and the rest just fell out of the stack. I cleaned it up and see there are no threads. The bathroom sink ties into it right next to it and it is threaded. Maybe this one is threaded and just covered by broken pipe.? I'll post some pics of when it was leaking,what it looks like now,and the pipe that came out. I thought I had a few minute job but I am not sure what to do with this. It is just a drain so not a lot of pressure on it. It's 4 A.M. here and I could not sleep so I started this job..lol. How do I reconect this?

that is/was a threaded connection....just like the connection to the plastic.....try cleaning it up first with a small fitting brush on the end of a drill you may expose those threads

Looks like someone stuffed a piece of copper in there and silicon ed it. Like Geofd said try to clean those threads up and then get an 1 /2" male pvc adapter and screw it in, or 2" not sure of that size looking at pictures. If you cant thread into it you may need to get a tap and try to run those threads to clean them up.

So you think there is actually threads in there,I have a dremel with a wire brush should I try to expose them?

 

[Lorne]

Metal ring in there I cant chisel out,not sure there is threads there.... grrrrr

Do you have a torch? If so, try heating that "metal ring", after stuffing a towel in the hole. It looks like it might be lead, left over from an old lead and oakum joint. If it is lead, it will melt easily from the heat of the torch. That will expose the threads.

If you don't have a torch, you can try cutting that ring with a hacksaw. If it is lead, it will be very easy to saw through. Cut it in two places and grab the ends and bend them in towards the middle.

Oh boy,this is sounding rough,I have none of those things but my neighbor does. Guess I will try this afternoon. What are my odds of wrecking this stack,I cannot afford to replace or fix,which is why there is no plumber here.

if there is still part of a fitting in there cut (just into the fitting) at 4,5,6 on the clock...try tapping out the cut pieces then you could try tapping at the ends it may loosen up or start caving in put a rag in the fitting so pieces don't end up there

here is the piece that came out,so I guess the ring is lead?

My conclusion from every ones help is that it is lead, I shall cut it or melt it out and then smash one of these donut puppies in and hook the drain back up.
Thanks for the help,wish me luck, will post results tomorrow.

you will know if its lead if its soft it will mark easily with a screwdriver I would not advise using a torch

 

[Diehard]

Doubtful it would be lead.
More likely some sort of epoxy.
If you do manage to get some threads exposed, you may want to try screwing in a piece of metal pipe. If nothing else but to clean and test it first. Before wrecking a PVC fitting.
If no luck with the threads, you may want to consider a similar approach of patching with a sealant. Like a 2 part epoxy or the like.

As Geofd advised, do not use a torch in a wall cavity.
