Methods For Replacing Your Damaged Or Malfunctioning Sewer Line

When you're dealing with a sewer line that's clearly damaged and in need of replacement, you'll find that you have a couple of options to choose from in order to resolve the problem. Understanding those options is essential because you will need to decide which path you wish to take to address your sewer line problem. Here's a look at the choices available to you so that you can make an educated decision. 

Traditional Excavation

Excavation is the traditional method for addressing sewer line replacement. If you have a sewer line that is cracked, damaged, or otherwise needs to be replaced, you could have the whole line dug up, physically removed, and replaced with new pipes. This also gives you the opportunity to consider installing a larger pipe if you have found pipe diameter to be part of the problem. This is labor-intensive and disruptive to your yard, so make sure that you're prepared for that and can keep the area secured from pets and children while the work is done. If you're dealing with extensive damage or old and brittle pipes, this is often a necessary approach to resolve the problem.


If you have a pipe that's just starting to show signs of cracking, you might be able to get a few more years of life from the system by asking your sewer line repair technician for relining. With the relining process, there's no trench to be dug. Instead, a tube is run through the sewer line and inflated to apply a layer of epoxy to the pipe walls, then deflated and removed from the pipe. The epoxy hardens on the inner walls of the sewer line, creating a solid surface of a new interior liner. This can extend the life of a sewer line that's in the early stages of cracking or corrosion.

Burst Replacement

Many people don't realize that you can actually replace sewer lines completely without having to dig them up. Trenchless replacement, often called burst replacement, relies on one single access point, so there's only one spot to dig. Then, a pneumatic head is run through the entire length of the existing sewer line to shatter the pipe or "burst" it apart. As that head moves along a pipe, a new pipe is pulled into its place. This replaces the existing sewer line with a new pipe, and can even be used to install a larger diameter pipe if necessary.
