Hello! I have a 4-in 3-in PVC pipe descending through an external wall from two bathrooms upstairs. We found a leak after moving into my new home and my real estate agent recommended a plumber who did the fix you see in the picture. I've sat on it a few months while working on other projects.
Problem is, the larger coupling sits nearly 3/4 in out from the joists and pushes the pipe out a bit as well, so drywall won't fit flush.
I wonder if the existing 2 couplings might be removed and replaced with an internal coupling and a new pipe run from the internal coupling to the sewage pipe in the crawl space. I'd appreciate your advice!

Thanks!
