How Does Trenchless Sewer Repair Work?
A traditional, trenched sewer repair requires plumbers to dig a large trench in your yard. They need to cut through your well-manicured lawn and beautiful landscaping in order to remove the damaged sewer line and replace it with a new one.
In addition to being messy and unattractive, trenched sewer repair can also severely damage the root systems of trees in your yard, which can kill the trees and fundamentally alter the landscape you’ve invested so much time and money to achieve.
Trenchless sewer repair, also known as pipe bursting, provides an alternative that saves your yard from mountains of dirt and keeps your landscape intact.
The plumber breaks up a small section of the basement floor where the sewer leaves the home. Another hole is dug at the other end of your yard where the sewer begins. Once the plumbers have accessed the sewer at both ends, they feed an elevator cable through the existing sewer line. On one end of the cable, they attach your new sewer line, which is built on-site in your yard out of high-density polyethylene. On the other end, a machine pulls the cable through the old pipe with 60,000 pounds of force.
With the cable comes the new sewer line, led by a wedge that advances through the old sewer, breaking it and pushing the fragments out in all directions. This makes room for your new full-sized sewer to come through.
Many think that the new sewer is smaller in diameter than the old one. This is untrue. The new sewer must be the same size as the old sewer.
