We lined the sewer from a clean out on the overhead stack, lined about 6’ out from the house starting our liner in the 4” PVC and ending our liner in the 6” PVC, lining through a break/ shift on the 4” cast just outside the foundation wall that was getting heavy root growth causing the sewer to back up. With the liner it smooths out the shifted pipe and keeps the roots from growing into the pipe causing sewer back ups. Also saves the customer from having to do any restoration work on the yard.
