Related to this thread where I outlined the problem of having a sewer smell coming into our house via the perimeter drain in our basement catching ground water:
Getting ready to replace the cast iron lines from the house to the septic tank, and when we do so, we are going to do a bit of drain line replacement inside the house as well. Here is what I've currently got going on.
We plan on cutting out all the cast and replacing with PVC except for the vent stack that runs through the roof.
I've read a bit about making sure the vent stack is supported when you cut the rest of the supporting drain lines away below it. What is the best way to do that? We'd be cutting it right where the word "vent" is on the photo.
Second question is related to how the vanity sink drain is connected to all this. As you can see, it currently runs vertically into the basement very near the main drain stack, but instead of connecting in the most direct way, it then runs horizontally away from the main drain stack and does this:
Any reason why I can't connect it more directly when I redo everything? Or is there a venting related reason this was done this way?
