I'm replacing the drain pipes under my bathroom sink and having trouble removing the final section behind the escutcheon that connect to the wall fitting. I have a metal pipe extension pushed into a brass nipple fitting at the wall. The extension is trapped in the brass nipple via a washer that is internal to the brass nipple so I cannot pull it out without removing the brass nipple. The nipple has a hex nut but it's inset in the wall behind the tiles. I cannot turn it without removing tiles and causing wall damage. What to do?

    That is an unconventional assembly! Was there a nut screwed to those threads or was it just like that? Commented Aug 5, 2016 at 21:56
  • Yes, there's a nut. I've included a photo of it here: i.imgur.com/QM0NDw1.jpg

  • Have you tried twisting and pulling with a fair amount of force? That type of connection is usually a slip-joint fitting and can be pulled directly apart. The presence of the brass ring is pecuiliar, however; usually a rubber slip-joint washer would be found there. Commented Aug 7, 2016 at 17:24

Cut the extension pipe off close with a hacksaw.

Then use a regular socket on the brass nut.


You could always cut into the wall just enough to do your work and then put a larger cover around the pipe to hide your mess. I'd find the cover first before cutting the wall so that you know for sure how much you can cut.
