ABS drain pipe to sewage broke at this part. I fear I have to replace into the concrete. What would you do for a minimally invasive repair?

enter image description here

Can I somehow keep the elbow piece? If not, how would you go about fixing this?

  • It may be possible to heat and pry the pipe remnant out of the fitting.

  • You likely won't have to, but going into the concrete is not all that hard when needed.

You can use an ABS/PVC pipe reamer to remove the broken section from the fitting side, then glue in a replacement pipe like normal. Just make sure to pay attention to how far out you ream the pipe.

Here is an example of this, they go by different names, this one is a "socket saver": https://www.homedepot.com/p/JONES-STEPHENS-2-in-Socket-Saver-J44200/302575481


It's like a genie in a bottle! You get three chances.

You can try removing the broken stub from the elbow's socket. There are mechanical approaches, such as grinding with a reamer or sanding with eg a small sanding drum on a rotary tool ("Dremel").

Heat might help, though I confess I've only ever rescued the inverse situation and only with PVC, not ABS. The idea is to warm the plastic enough that it's pliable. You can then tug the pipe stub toward the center, separating it from the elbow's socket. If you get it right, the plastics separate at the solvent-weld layer between them.

If things go sour on the first try your second opportunity is to remove the elbow itself from the little stub of pipe connecting it with the vertical wye. If that too goes badly, the last opportunity is to remove the stub of pipe entering the wye's socket.

Since you do have several chances available to you don't be terribly stressed about trying something. Also, you may find it helpful to make up some practice parts by gluing a few new fittings from the store to each other so that you can test the techniques on those first.

  • Thanks. Any thoughts on the Socket Saver in Ron's answer? Jan 26, 2022 at 1:04

    @PatrickSzalapski I'd not seen a tool like that previously. Looks like it should do the job very easily. I'm such a miser and have so many tools already I'd probably spend an hour trying other things rather than buy one I'm unlikely to use again any time soon. Everybody's different in that respect!
