I have a cast iron drain pipe from my house to the lot line where it transitions to the town's PVC pipe (with clean out) that goes out to the street.
I have a partial blockage so I had the line scoped by Mr. Rooter. There is a mass of hair-sized roots hanging from the top of the pipe at the cast iron to PVC junction. The town says it's my problem even though they introduced that particular junction when they added the clean out about 7 years ago. I may make a few phone calls, but I doubt I'll get any relief.
Mr. Rooter gave me 2 estimates to line the pipe:
$2100 (tax included) to line a 4' section near the clean out which will seal the junction. That comes with a 5 year warranty.
$4100 (tax included) to line the entire pipe from the house and into the PVC, approximately 40 ft. That comes with a 25 year warranty. There are other junctions with push-seals along the 40' length, but they all appear to be solid. No roots, no separations, etc.
Obviously the full liner would be more cost effective, but that's a chunk of change.
Does anyone have any experience with having a drain pipe lined? A 25 year warranty seems to imply a pretty "permanent" fix, but of course the company has to be around to honor it should something go bad.
Any thoughts?
