If you’ve been told you have a broken sewer line, your first thought is probably, “They’re going to tear up my yard.”
The good news is that isn’t always the case.
Thanks to trenchless sewer repair, many homeowners can restore a damaged sewer pipe without extensive excavation, demolished driveways, or destroyed landscaping. Using advanced trenchless technology, plumbers can often repair or replace underground sewer lines with just a couple of small access points instead of a long trench across your property.
At Zurn Plumbing, our Precision Pipe Lining (PPL) team specializes in these modern repair methods, helping homeowners solve sewer line problems with less mess, less disruption, and long-lasting results.

What Is Trenchless Sewer Repair?
Trenchless sewer repair is a method of repairing or replacing an underground sewer line without digging a continuous trench across your property.
Instead of excavating the entire line, plumbers access the pipe through small access holes or existing cleanouts. Depending on the condition of the pipe, they may recommend pipe lining, pipe relining, pipe bursting, or another form of trenchless pipe repair.
The goal is simple: restore the sewer line while minimizing damage to your lawn, driveway, sidewalks, and hardscaping.
How Do You Know If You Need Sewer Repair?
Many homeowners don’t realize they have a sewer issue until it becomes impossible to ignore.
Common warning signs include:
- Slow drains throughout the home
- Frequent toilet backups
- A recurring sewer backup
- Gurgling drains
- Sewage odors
- Wet spots in the yard
These symptoms often point to larger sewer line problems beneath the surface.
What Causes Sewer Pipes to Fail?
Underground pipes face a lot over the years.
Some of the most common causes include:
Tree Roots
One of the leading causes of sewer damage is tree roots. As roots search for moisture, they find tiny cracks in aging pipes and continue growing inside them. Over time, tree root intrusion can block flow, crack the pipe, and eventually cause complete failure.
Corrosion
Older cast iron pipes commonly deteriorate due to corrosion, weakening the structure until leaks and collapses occur.
Ground Movement
Soil movement and settling can shift pipes over time, creating a damaged pipe or separated joints.
The First Step: A Camera Inspection
Before recommending repairs, Zurn performs a camera inspection.
This video inspection allows our technicians to see exactly what’s happening inside the sewer line.
A professional sewer inspection identifies:
- Root intrusion
- Pipe cracks
- Corrosion
- Blockages
- Collapsed sections
With accurate information, we can recommend the right repair instead of guessing.
Clearing the Line Before Repair
If heavy debris or roots are blocking the pipe, the first step is often hydro jetting.
Hydro jetting uses high-pressure water to remove grease, buildup, debris, and tree roots from the pipe so repairs can be completed properly.
What Is Pipe Lining?
One of the most common forms of trenchless sewer line repair is pipe lining.
Also called pipe relining, trenchless pipe lining, or CIPP lining, this process installs a flexible liner inside the existing sewer pipe.
The liner is saturated with epoxy resin, inserted into the damaged pipe, then inflated until it cures against the interior walls. Once hardened, it forms a durable new cured-in-place pipe inside the old one.
Because the original pipe remains in place, excavation is kept to a minimum.
What Is CIPP?
CIPP, or cured-in-place pipe, has become one of the most trusted methods of no dig sewer repair.
Benefits include:
- Minimal digging
- Faster installation
- Long service life
- Improved flow
- Reduced disruption
Many homeowners are surprised to learn that a severely damaged sewer line can often be restored without replacing the entire pipe.
When Pipe Bursting Is the Better Option
Sometimes a sewer pipe is too badly damaged for lining.
In those situations, Zurn may recommend pipe bursting.
During this process, a specialized bursting head is pulled through the old sewer line, breaking apart the existing pipe while simultaneously pulling a brand-new pipe into place.
This method is commonly used for trenchless sewer line replacement or trenchless pipe replacement when the original pipe has completely failed.
Traditional Sewer Repair vs. Trenchless Technology
For decades, traditional sewer repair meant digging up the entire length of the pipe.
That often resulted in:
- Destroyed landscaping
- Broken sidewalks
- Damaged driveways
- Torn-up patios
- High restoration costs
Modern trenchless methods dramatically reduce those disruptions.
Instead of excavating your entire yard, technicians typically work through a few carefully planned access points.
What About Homes With Septic Systems?
Whether your home connects to city sewer or uses a septic system, underground drain lines can still develop root intrusion, corrosion, or structural failures.
A professional inspection determines whether trenchless methods are an appropriate solution.
Is Trenchless Sewer Repair Right for Every Home?
Not every sewer issue can be repaired using trenchless methods, but many can.
Following a camera inspection, Zurn evaluates:
- Overall pipe condition
- Amount of corrosion
- Structural damage
- Root intrusion
- Pipe material
- Accessibility
If the existing pipe is suitable, trenchless repair often becomes the fastest and least disruptive solution.
