Your available sewer repair and replacement options will vary based on the extent of the sewer line damage, the location, and local codes. The most direct method of repair is to dig up the sewer line and replace it, but the extensive excavation required will take a long time and will create quite a mess in your yard. In some cases, trenchless repair methods may possible, such as installing a durable epoxy pipe liner in the existing pipe, or bursting the pipe and installing a new one in its place, both of which require minimal excavation.
