Is there anything that can be inserted into the sewer line under the house that will correct it. Somebody told my they thought that they had seen on the show This Old House sticking an inflatable sleeve in the sewer line and blowing it up to fix it. Has anyone heard of this and where can I find out more about it? I need some ideas.
The old pipe was a 4" clay pipe and they replaced it with PVC. The length under the house is probably about 25 feet and about 4 feet under ground.
