 Corroded pipe breaking off before I can remove it
Author: Loose Thread (MN)

Hi all,

Thanks in advance for the expertise and your willingness to share!

A dropped earring had me removing the p trap under the bathroom sink (no cleanout). Long story short, two pipes broke in the process. The threaded part of a chrome pipe broke off inside the pipe that is connected to the “drain” part of the sink. I don’t expect that’ll be much of a problem once I’ve removed it from the sink. But, if anyone knows of an easy trick to remove 2mm of threaded pipe from inside another ... I’m all ears.

The real problem is with the pipe sticking out of the wall I believe that it’s the stub out? The brass trap tube (if I’ve got that right) is broken off and is badly corroded. We’ve been here 3 years and this is the first work I’ve had to do on this sink.

I’ve heated the tube with a torch for about 3 minutes and tried pulling it out, but it just breaks off every time. It’s so brittle.

Any suggestions?





Thanks again!

Short time repair would be to trim stub off square and attach new trap arm to it with a rubber tubular coupling. Best repair entails opening the wall around the stub to gain access to the stubs attachment to the in-wall piping and replace the entire tube. The stub is probably soldered to a threaded brass ring, that's screwed into a metal fitting. The broken tailpiece from the sink drain can be removed from the drain assembly, by prying the thread loose and unwinding with a needle nose plier.

I was coming on again to use my computer instead of the phone. I'd posted with my phone and I didn't think I'd actually got any pictures up. Amazingly, you've got that sorted out too Steve!

Thank you for the reply. I'll try my hand with option A and if that doesn't work, I'll call in a pro.

All the best!

Looking at your updated pictures, it looks like inch and a half copper coming out of the wall, that had a threaded adapter soldered to it
and the ABS trap assembly screwed to the adapter?
