There are two major repair methods in trenchless sewer repair:

• Pipe bursting: the old pipe is broken into, and a new pipe is laid in its place
  • Two access holes are made, one for the sewer line from the house, the other from where it join the main sewer line
  • The new pipe will have the same diameter as the old one, allowing the same amount of flow from the home to the main sewer

• Pipe lining: a flexible pipe is coated and then blown/pulled through the old pipe
  • The new pipe is inflated once it is place, creating a pipe inside of a pipe
  • This lowers the diameter of the sewer pipe by about ¼ of an inch
  • For most people it does not have enough of an impact on a home’s drainage needs
  • Sometimes the method may not even work

Pros and Cons of a Trenchless Sewer Line:

• Pros:

  • Less invasive

Overall, the trenchless sewer line’s repair is very effective in the long-term in terms of cutting costs. It is also more convenient in terms of property disturbance and disruption.
