Figuring out whether or not your broken sewer line is repairable is the first step in dealing with it. If the damage is small enough and restricted to a limited portion of your sewer line, it is possible that a patch can fix the problem. Repairing a broken sewer line with a patch is simpler, quicker, and less expensive than replacing a large portion or all of the sewer pipe. If you suspect you have a leak, the sooner you act, the more likely you are that it can be patched, rather than having to be replaced.
