Howdy folks, while doing my routine plumbing check I found a leak at the area where everything drains out of the home. The home was built in '68 and is unfortunately all copper. While it has made small repairs easy, this one has me scratching my head. My thinking is to replace this area with PVC. I don't know whether to tackle it on my own or call a good plumber. Here is a pic of the area. At this point, the leak is small at maybe 4-5oz a day, but she could go at any time! Already a quick patch job in another spot so that is why I am thinking of gutting and replacing.
