Questions About How A Sewer Line Can Be Repaired With A New Lining

Do you have an old cast iron sewer pipe under your yard that needs to be restored, but you don't want to go through the costly process of digging up the yard to replace it with new pipe material? The best way to do this is by adding a new sewer pipe lining. Here are some questions about how it can be done for your home. 

What Is A Sewer Pipe Lining?

The pipe lining process involves creating a new pipe within an old pipe. There are a couple of ways to get this job done, but one of the most common ways involves applying an epoxy to the exterior of a tube. The lining is fed into the sewer line with a balloon inside the tube, and then the balloon is expanded inside the new lining so that it seals against the inner walls of the pipe. The new lining ends up being a fast and easy way to fix a pipe so that you get more longevity out of your lines.

How Do You Know If A Sewer Pipe Can Be Relined? 

The best thing to do is have a plumber come out to your home and evaluate the pipe itself. They will do this by placing a sewer camera in the line and seeing what kind of existing damage has been done. If the pipe is significantly damaged, such as being partially collapsed, it may not be possible to fix the pipe with a new lining. If the plumber discovers tree roots and other debris in the pipe, they will need to clean all of the tree roots out before a new lining can be installed.

What Happens If Tree Roots Grow Back?

The problem with tree roots is that they do grow back, and chances are that they will eventually grow back into the pipe that you had relined. You'll still need to stay on top of having your sewer drain snaked regularly to keep it in top condition. Tree roots may grow back through the new liner, but it will not have the extra stability with the liner being held in place by a new epoxy.
