Believe it or not, a broken sewer line covered by insurance is a fairly common thing to hear about. Sewer lines, including the pipes that lead sewage and greywater out of your home, are considered to be a part of your home. As long as the lines are on your property's boundaries, there's a good chance that you will have them covered. Of course, the coverage you get is still based on the same rules as most other aspects of your insurance policy. The way that your policy works is simple: if stuff happens to your sewer line that's beyond your control, you will be able to get your sewer line replacement covered by insurance. So if a tree falls on your sewer line or an earthquake disconnects it, you will be able to file a claim successfully.
