Residential sewer lines can fail for numerous reasons. Old pipes may wear down and even collapse with time, but other issues may also occur. For example, roof infiltration can potentially cause enough damage to ruin otherwise intact plumbing sections. Unfortunately, repairing a failing sewer line can often be expensive and time-consuming.

Because this job is so potentially disruptive, you'll usually want to choose an option that's both long-lasting and cost-effective. You have three main options for a typical sewer repair: traditional dig methods, pipe bursting, and lining. This article will help you understand the advantages of each and why you may want to choose one over the others.

1. Traditional Dig Method

Conventional sewer repairs are a brute-force solution that requires both time and effort. Traditional repairs involve excavating and exposing the damaged section of your sewer pipe. Once they've uncovered the problem area, the plumbers can replace the impacted section of plumbing and backfill the trench.

Traditional methods are costly and messy. However, they may be the best option if your old pipe is too worn-out or corroded to be a good candidate for the other methods. Conventional digging can also sometimes be cost-effective if you aren't concerned about the landscape above your sewer. In these cases, your total costs may not be much higher than alternative methods.

2. Pipe Bursting

Pipe bursting involves inserting a new pipeline through the damaged section of pipe, "bursting" the old one out of the way in the process. This method can create a reliable and long-lasting repair that's equivalent to traditional digging, with the added benefit that it's not necessary to remove the damaged portion of plumbing.

While pipe bursting is often an excellent option, it's unsuitable for all situations. Factors such as the condition and material of your old pipes and the surrounding soil type can impact whether bursting is appropriate for your home. Pipe bursting also still requires some excavation for the entry and exit points of the new pipe.

3. Relining

Pipe relining describes various techniques that allow plumbers to insert a flexible pipe liner in your old sewer lines. These liners fill the old space, sealing any leaks or damage. Once in place, installers use cured epoxy to create a permanent and rigid repair. Relining may require less excavation than pipe bursting, often making an excellent option if you need to avoid causing too much surface damage.

However, relining also isn't suitable for all situations. Some pipes may be too damaged to work with a liner, and local building codes may require plumbers to replace certain materials. In these cases, you'll need to work with your plumber to determine the best option to conduct a permanent repair that meets local building codes.
