Sewer drain connection question

This is what I have and what I'm dealing with. I have a 1 1/2" copper stack coming down the wall with a "T" fitting. From the T it comes out horizontal for 2' with 1 1/2" copper pipe then goes into a threaded 1 1/2" pvc pipe that goes up to the kitchen sink after some bends and 10' of pipe. Well for some reason the 1 1/2" of copper 2' peace decided to split for no reason. So what are the best fixes for this? I was thinking to take out the copper 2' peace and threaded pvc fitting and add pvc slaved coupler with a new pvc pipe and slide the pvc pipe right into the copper T fitting. And use a 1 1/2" by 2" flexible rubber coupler fitting to keep the pvc and copper T together. Is that the right way and best way to do this? All that comes down this line is the kitchen sink and dishwasher.

thanks

Can you post a pic of all the pipes under the sink?

If the horizontal piece is leaking, just cut it out with a sawsall & use rubber couplings to install a piece of PVC.

I can't see above the tee, 2" copper pipe?

Ideally you cut out the tee at the lines and replace with a PVC tee.
You can use a standard sized shielded no-hub coupler at the bottom.

At the top, You will need a special no-hub coupler that might not be available at a home store. You need a copper to "standard" no-hub coupler. Standard is PVC/ABS/Cast, the copper has a smaller outside diameter. A real plumbing store should have the no-hub.

The far right line is where you will tie into the existing PVC, using a no-hub.
