Central Coast Pipe Lining

Any ideas of how I can pull a liner or flexible pipe through the 43 clay pipe which also bends slightly? Currently, run off from the downspout runs under the house and there is no other place to go with the drainage. Bill, there are firms that specialize in lining failing pipes, but I'm not aware of any liners that you can use yourself. I would suggest that you contact a plumbing company in your area that has sock lining technologies.
