Tree Roots growing into plumbing

[Shane Quin]

I have a duplex where the plumbing was getting backed up.

Had a plumber go out there and put a camera in the lines and turns out there are roots growing into the plumbing from a nearby tree.

The quote to rip out and replace the plumbing was a staggering number.

My thought is to cut down the tree to stop the growing and then eventually put the liner in the plumbing.

Any experience with this?

All advice appreciated.
