What kind of experience do others have with lining their main sewer lines?
Earlier this winter I had a very bad block to took the plumber a good deal of effort to clear out (he ended up using a pressure washer type of snake to free it up). Once it was clear he did a video inspection and found the line was in pretty good shape except that there was channel eroded in the bottom of the line with exposed aggregate (the line is made from sections of concrete pipe).
The plumber proposed lining the line since it was still in pretty good shape, and considering it is the original drain line from 1942 this sounds reasonable. I would just like some input on the different types of liners available, their relative costs, and longevity. The line is approximately 110 feet with one 90 degree bend where it goes around the house.
