Dripping from ABS pipe joint

[hardywang]

I have a leaking under one of the sink drain of 2nd floor. I cut my 1st floor ceiling open and I saw it (image you look up and see what is in the picture):

I feel the water comes from the joint, the lower part is wet. But the water droplet eventually forms on the joint.

I understand the proper way is to cut the straight pipe and redo it. But is there some other easier ways?

• Epoxy putty? Can I use it to build a ring around the joint? Is epoxy durable?
• According to this video (http://www.finehomebuilding.com/2014/01/24/how-to-patch-a-leaky-pvc-water-pipe), if I use ABS glue and a coupler instead. Do you think it could be fixed and last for long time?

Nothing short of a full replacement will work.

It is so easy to do a proper repair on that situation, it would be silly to try to a bandaid repair. Cut a little more drywall, and the repair should take maybe 1/2 hour. Should even be able to use regular glue couplings, what with all of the room for movement that oversized hole gives you.
