|In response to Re: Old Sewer line|
: You have the advantage of Trenchless technology on your side. Television camera color inspection of the sewer line, its damage, its location, and its estimate to repair are readily available in your area. Look in the yellow pages for pipeline rehabilitation. Companies insert a small robotically operated video camera and light into the sewer, find the weak and damaged spots to see that all is okay for a repair, and insert a resin impregnated baloon into the sewer from the house to the mainline. Then they inflate the baloon with high heat low pressure steam to exactly fit the sewer line as an inside high tensile strength liner, they allow the liner to heat temper, then slowly cool; then they insert a cutter to cut the end of the baloon off, and you have a newly rehabilitated sewer line good for another seventy five years. One such company is SWERP Inc, at (800)507-9370 (but they're in Pa.) If you cant find another closer to your home, e-mail me at email@example.com for help
Is this liner truly strong enough to last 75 years (or even 40)? What if there are gaps at the existing breaks in the pipeline -- does the liner bubble through and cause weak spots? Are tree roots able to poke through the liner? If a liner is just as strong as a new pipe, then this sounds almost too good to be true, especially if it's appreciably cheaper than excavating.
