Pipe replacing can be expensive, but better in the long run. My house in PA, I had to have it replaced from the back of the house to the halfway under the street replaced. Luckily, most of it was covered under the house warranty, but it was a total of $13,000 to have done. They dug up my basement, and replaced it all the way out. It caused my neighbor to have to pay for part of it, since their line Y'd into mine...something that was done over 100 years ago when the homes were built. Their crap was coming into my basement. It was a big job, but it's done. The weight of the ground, sidewalk, and road crushed everything, and nothing went to the sewer like it should have.
