In response to Re: Sewer relining rather than replacement?
As long as the roots are completely removed so they do not cause bumps in the liner, and the pipe is relatively straight so you do not reline a porly pitched or deflected sewer, you should be in good shape. It is a process that many cities use to repair their sewer mains.

: Hi folks, I hope someone here has the experience to give me some advice.

: I live in an 87-year-old house whose sewer line is probably the same age. I wasn't smart enough when I bought the house to have the line camera-ed, find the problems, and subtract the cost of the replacement from the house price :-(

: Long story short: the sewer line is in really bad shape (it's clay), and I have constant trouble with roots from the trees that live right above it. To dig and replace will be expensive - it's in a fantastically tight and inconvenient location, and half the length will have to be dug by hand, down to about 8 ft :-( I've had a bid to reline the pipe with what I believe is called "cured in place pipe". It's like a vinyl sock that they blow down the tube, fill it with hot air, and it cures into a rigid lining inside the old pipe.

: I've had a couple local plumbers tell me they think it's a band-aid - they don't believe in it. Others have never heard of it. The cost to do this is half of the cost to dig. I know it won't be as good as a new pipe, but if it'll last even 10-12 years, that may be good enough.

: Does anyone have experience with this stuff? Should I get the lining? Thanks very much for your help.
