Hi, I am a homeowner just looking to educate myself. I have a old concrete section sewer pipe from 1942. We just had the last 82 feet preventatively relined. I was not exactly happy with the company that did it for various reasons. So I am posting here because I do not really trust them. The upper 25 feet of my sewer pipe has a few incoming pipes like the upstairs kitchen, and a basement sink. There is some root intrusion in this 25 foot long pipe. One day it will need to be addressed. I'd like to know if it's possible to reline a sewer pipe that has 2 or 3 incoming pipes? and how that is done, if so.
