This is not what I have seen. All of the original metal pipes I have checked had major corrosion on the inside, even if they looked ok on the outside. The pipes are made from seamed tubing. The seam runs the full length of each pipe. The seam is where the worst corrosion occurs on the inside. One pipe does always look worse than the other. Even a pipe that looks ok inside on the ends can have grape or pea sized nodules growing elsewhere inside, along the seam of the pipe. Mark
