1920s house with cast iron drain pipes. I need to replace a sewer line under the basement floor that I have been told has belly in it (had a plumber snake and then camera it when it backed up a second time). Nothing else ties directly into this line as the backup only affects one thing (an upstairs toilet).
The issue is this line goes from vertical to horizontal (underground) in the unfinished side of my basement, travels under a wall and ties into the main line in a finished area of the basement. Instead of digging up the entire line and dealing with tearing up the finished side, my thought was to dig up the initial section of pipe in the unfinished side, cut and cap that line off, then reroute to pipe so it ties into a 4" main line that has already been replaced with PVC in the unfinished area. This would not only avoid digging up pipe in the finished side of my basement, but it would require about half as long of a trench.
Any issues with capping the old pipe? It would still be connected to the main line, but unless something gets backed up then sewage should never enter the pipe again.
Thanks!
