Hi, So one of my friends recently purchased a single family home. Recently they did a camera inspection on the main line, and the inspecting plumber noted that the pipe had tree roots on several parts of the mainline. The plumber recommended a sewer trenchless replacement. They also mentioned they would seal the replacement pipe with some kind of "sealant" so that tree roots couldn't get in their again.
There doesn't seem to be an immediate problem with blockage in the line. The only thing my friend noted is that when there was a heavy rain, and they did laundry, water backed up into the master bedroom shower and the secondary bathroom bathtub. So clearly there's a problem, but on other days there's been no issue so far.
Some questions:
1) Can my friend simply "hydrojet" the line to deal with the issue or is a replacement needed?
2) What's a reasonable estimate for this type of work (both for replacing and/or hydrojetting)? (they live in Southern California, Ventura County - Westlake/Moorpark area; you can think Los Angeles if you're not familiar with Ventura).
3) What is the name of the "sealant" for the new pipe that the plumber was referring to so I can compare brands/solutions?
