Very like the pipe will have to be replaced to solve your problem.

That is what I am starting to thing. Minimum 2 day job. ANd because the job is so deep (15 feet) OSHA requires a brace which costs $1000 grand a day. That is just for starters. I think the permits are around $500 too. ANd that's not even counting the heaving machinery yet.

Yup, it’s like that here too. They would have had to dig a deep trench, etc. I liked the inside-sleeve plan, but the RootX did the trick. For now.

I had a similar problem in a house I rented. About twice a year the line had to be cleaned out, finally I moved and left it to someone else.

Oft times in older tract houses cheap tough trees were planted that would survive anything but they were usually ones that put down deep roots and were water loving.

My plumber wanted $750 to install another clean out and recommend cutting down the problem tree, several more hundreds, or replacing the whole run of pipe. $2000 doesn't seem unreasonable even if painful for the work you suggest.
