I recall seeing a plumber repair a sewer pipe from the basement of an old house to the street with this sort of tool. It had some epoxy that was injected first to glue the new liner to the old rotting pipe. It was on an episode of This Old House on PBS.

I have a question, in cities like Flint, MI where the lead water pipes "lost their lining", is this the type of liner they lost? Or, is this a possible solution for fixing the existing lead pipes instead of digging them up for complete replacement? If this is a possible repair, wouldn't this save millions of dollars, and be much faster than replacement, in the rest of the cities around the country?
What is the longevity of this type of liner?
Very curious!

It is feasible for the mains but the small diameter service lines would not be lined,

Wasn't sure exactly what I was seeing at 23 sec! Thought it switched to a medical video!

A friend of mine had problems with the soil line from his house to the city sewer. An old clay pipe segmented line that had tree roots growing through it the Plumbing company convinced him that all they would have to do would be to run a rotary cutter snake through the line then line it that way they wouldn't need to dig up the line and replace it. after running the cutter several dozens of feet through the line they determined they must be into the main sewer by now. so they ran the liner in and ran water in it to test the system after a few minutes the water backed up and wouldn't drain, but a few minutes later it began to drain They determined the job complete. A few months later his problem returned so he called them back. After several days of work they finally completed digging up all of the line and replacing it. The cutter had hit the tree roots and deflected out the side of the pipe and made its own path along side the soil line Only missed the city main by a few feet and wound up under the road in a gravel filled cavity that had been filled when the road was built quite a mess I imagine

Isn't this why remote inspection cameras were invented?

Not every plumbing contractor maintains the latest in tech or if they do they don't always employ the use of their tech.
I've known companies who did horizontal boring loose the bore probe signal and continue on boring hoping they will retrieve the signal on the other side of a street, only to learn that their probe had taken its own course to exit many yards off target due to it being deflected by a hard obstruction or bore through a Nat gas pipe while trying to hit a sewer line.
I would have thought in the case of the cutter snake they would have noticed something was amiss long before reaching the street Who knows The soil line may have been routed at an angle to the city line
