Lining a pipe - GIF

[Frank S]

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
