What Trenchless Repiping Is All About and Why You Should Consider It if You Need New Pipes

If you are like most homeowners, you probably haven’t thought much about your sewer pipes. However, like any other plumbing component in your home, your sewer pipes can fail due to age, shifting soils, or other factors beyond your control.
When sewer pipes fail, they will need to be repaired or replaced. Unfortunately, conventional repair and replacement can be incredibly disruptive to your home and its landscaping. That is why trenchless repiping is a technology worth considering when you are looking at having your old sewer pipes replaced.
This exciting technology offers many advantages over conventional sewer line replacement. Below is more information about what is involved with trenchless repiping.

What Is Trenchless Repiping?

Sometimes called pipe lining or cured-in-place piping, trenchless repiping is an innovative procedure that restores the original function of your sewer pipes without anyone actually having to remove them. Below is a step-by-step summary of how trenchless repiping works.
1. Clean and inspect the old sewer line
In this step, the plumber will use a hydro jet or other pipe cleaning system to scour the inside of the existing sewer line. The purpose of this thorough cleaning is to remove roots, grease and fats, and other potential obstructions.
Trenchless repiping can still be performed if there are cracks or other minor areas of damage in the line, including slight misalignment issues. However, the line needs to be as clear and clean as possible for the best long-term results.
2. Prepare a section of uncured pipe liner
Once the affected section of sewer line has been cleaned and measured, a length of felt tubing will be selected and cut to size. Next, the plumber will saturate the felt tubing in a slow-curing epoxy resin until it is well-coated and then set the tubing aside.
3. Insert the uncured pipe liner into the old sewer line
After preparing the felt tubing, the plumber will create an access point to gain entry to the old sewer line. The saturated piece of felt tubing will then be inserted into the opening of the sewer line, and pneumatic pressure will be used to force the tubing into the line.  
The felt tubing will inflate and press up against the interior of the old sewer pipe; air pressure will be maintained to hold the tubing in position until the epoxy resin cures and the cured-in-place pipe Is able to maintain its shape.
4. Reattach all plumbing connections
When the section of cured-in-place pipe has been installed and has had sufficient time to harden, the plumber will use a camera to inspect the interior of the line to ensure the relined pipe is ready to return to service. Existing connections will then be restored, and the line will be tested for proper functioning.

The Advantages of Trenchless Repiping

Trenchless repiping offers a number of advantages to homeowners. Below are a couple of key benefits:
Less disruption of landscaping and structures
With conventional sewer pipe replacement, plumbers are forced to excavate lengthy trenches that can tear up lawns, trees, and other landscaping features. In some cases, existing structures such as fences or foundations may need to be torn apart to gain access to the sewer line.
However, trenchless repiping involves very little digging, and it leaves almost no evidence that any work was ever done.
Faster work times
Another key advantage offered by trenchless repiping is the short time in which it takes to perform the work. Rather than taking days or weeks, trenchless repiping allows plumbers to repair poorly functioning sewer lines in a matter of hours. This means you can have your plumbing back in action sooner than you might have otherwise thought possible.
