I have a 4″ clay pipe which is a downspout drain and is leaking.  The pipe runs under an addition to the house.  There isn’t sufficient space under the addition to access the pipe at all.  Any ideas of how I can pull a liner or flexible pipe through the 4″ 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. You may require access from one or both ends depending upon which sock lining technology is used.
