I hope someone can offer some advice.

I have just purchased a new home and have found my sewer line is filled with roots. I have a downstairs (basement) bath (shower, toilet, and sink) that are almost blocked. Essentially it's good for one flush, and then everything comes to a hault.

A plumber who worked on clearing the drain (just prior to close) found the pipe full of roots and he did his best to rotor root it. Yes I now have a lawyer involved. But lord only knows if I'll ever get anywhere with that.

So the first thing I have done is hired my on plumber to put a camera down the clean out on the stack. He found numerous roots and a blockage that he could not get his camera through not far from the stack, under my laundry room floor, and just before the floor drain.

So he went to the clean out on the other side of my house to see if he could get the camera down there and come back to the other side of the blockage. As soon as he took the cap off, he saw roots, and decided that he could not even put his camera in.

Fortunately, my plumbing continues to flow, but for how much longer I do not know. This plumber advised me to replace the entire line. That would be 30' of trench under my basement floor and then perhaps 50' to the street. I have not yet seen the estimate for this, but it is going to be a lot.

Now for the advice :-) I have heard of a process called "pipe lining" (I think) where the root out your sewer and then they coat the inside of your pipe with something that keeps the roots from coming back. But I can't seem to find out much about this, and I'm suspicious that it would work.

Then, what about rotor rooting it all out and applying root x to it. There is a local company that claims to have great success so long as they apply the root x immediately after they cut out the roots. Of course I know this will not be permanent. But I figure that if I did this every year for the 20 years, it would still be cheaper than replacing the entire line.

Then there is all sorts of talk about rock salt being able to kill roots or copper sulfate.

Oh and finally, there is some new process where they dig holes on either end of your line and then they burst the existing pipe and pull in a new line in its place without trenching.

I going to try and get an estimate for that later this week.

I suppose what I'm really hoping to hear is form folks who have had experience with root x or with relining their sewer lines.
