re: How hard is it to replace a section of copper pipe

So not the supply. It is the drain. I replaced the rubber on the pvc to copper connection and it is still leaking. Except it is more like sweating from the top of the pipe. Am I looking at replacing the copper with pvc drain or is there a patch for copper drain pipes?

Looked at it again this morning with a fresh set of eyes. It is 1-1/4 copper going down about 3 feet and connecting to a larger cast iron main drain pipe. I'll need two 90 degree pvc joints. One to go left after it enters the wall, and another to turn down to the basement. From there I think I can route it towards the pipe pretty easily since I'll have more room to work. What is common for joining PVC to cast iron? It does have a larger connection at the iron, I'm guessing 3 inch. From there it joins up with the 4-inch main drain further down, but I only need to connect to this point. The only thing going through this is the sink and dishwasher drain, so no need to go larger than 1.5 inch PVC.

Quick update and thanks to the OB. I figured out that it wasn't the drain, but to make a long story short, I replaced the drain anyways, and that is when I found the leak on the hot water line. I used the sharkbite and pex to repair that. Worked great. The actual cause of the leak was the old water filter. Two microscopic holes squirting the tiniest streams of water, over to the left, and hitting the drain pipe. Like I mentioned last week, it looked like it was sweating on the top of the old metal pipe. Well, that was actually this little stream of water, more like a mist, hitting the pipe. Either way, I got it all repaired and learned a lot in the process. PEX is awesome.
