    Please see attached picture. Upper 90 deg elbow is cracked at the trap fitting. It will not loosen from its drain connection despite heating. There does not appear to be a lot of room to install a new piece if I were to cut the elbow out. Any suggestions?

    Thank you.

    So you're sure it's the top piece and not the bottom.

    That joint you try to loosen, even with heat is an solvent glue connection.
    There are many videos showing different methods of removing pipe from a fitting. Not an easy job but apparently doable so long as you don't ruin it.
    In your case you want to remove the fitting off the pipe. Not easy.
    I believe you would quickly see what you would have to do to peel pieces of the hub away from pipe, after watching some of those videos.

    I would think cutting the pipe flush with the face of the Tee branch and either try removing the piece of pipe within using cut, heat and peel method OR better yet get one of those "Socket Savers"...
    https://www.amazon.com/Jones-Stephe...+Saver,+1-1/2-Inch&qid=1573263338&s=hi&sr=1-1 and drill it out.


    OR...not knowing how bad the crack is, maybe a temporary repair would be worth trying. For example, if crack is in the threads of the lower half, remove follower nut, wrap with Teflon tape and screw back together. I would even try a tight wrap(once around) of black electrical tape.

    The upper elbow ends in an unthreaded male taper that is compressed (by the nut) into an unthreaded female taper recessed in the trap. The outside diameter of the trap is threaded to accept the nut. The upper male end is cracked vertically, about 1.5” long.

    Yeah...that's a pretty substantial crack. I was hoping it was in the threaded portion.

    EDIT: Although plumbers do not patch things but I suppose there's always a chance of a good 2-part epoxy will stop the leak.

    It is ABS. Do not try epoxy. If I wanted to fix the crack, I’d spread it slightly, and just rub, ABS cement into the crack. I think you’d stand a better chance of getting things sealed that way, than with epoxy.

    That said I’d have to determine why it is cracked in the first place, before doing anything.

    I would add putting a large hose clamp around the fitting applying the ABS cement.

    Thanks for the tip about the socket saver, diehard. That worked really well. No leaks. Appreciate your help.

    I had to upsize an old tub drain to 2" to accommodate a shower. The old tub drain (1 1/2") entered a 3" stack thru a 3 x 1 1/2" bushing in a 3" double wye in the stack that was practically impossible to remove and replace. I made my own "socket saver" to remove the old 3 x 1 1/2" bushing and put in a 3 x 2" in its place, by combining a 3 1/2" holesaw and a 1 5/8" holesaw on a single Bosch HE-1 mandrel. I ground the teeth off the OD of the 1 5/8"; it fit nicely inside the existing 1 1/2" pipe glued into the bushing (1 1/2" ABS ID is 1.615"), and acted as a guide for the 3 1/2" which then cut the bushing at its OD ( 3 1/2", same as the OD of 3" ABS).

    Now “that” is actual MacGyvering!

    You should patent that, sell a whole set of combo saws like that.

    It a thought but likely wouldn't work for most sizes of either ABS or PVC.:D
