No. The best advice is to have someone come to camera your sewer. Make sure you know all of the facts before someone talks you into a whole sewer replacement. Unless you visually see what your sewer line looks like inside, you cannot determine the cause. It is best practice to watch the screen with the person running the camera, and ask a lot of questions. You may find that you just need to snake the sewer to clear an area or you may see a break in the sewer line which would require a repair.
