What Sewer Cleaning Works in Tree Roots Invasion
Updated: Aug 20
Imagine a relaxing evening at home suddenly turning into a plumbing nightmare. You flush the toilet, but instead of everything flowing normally, the water rises. A sink begins to drain slowly, or worse, wastewater backs up through a floor drain. In many cases, the problem may be hiding underground in your main sewer line.
One of the most common causes of serious sewer blockages is tree roots.
Trees add beauty, shade, and value to a property, but their roots are constantly searching underground for water, oxygen, and nutrients. Small cracks, loose joints, and aging sections of sewer pipe can provide an opening for tree roots to enter.
Once inside, the roots can continue growing and trap toilet paper, grease, debris, and other waste until a serious blockage develops.
The good news is that professional sewer cleaning can often remove root-related blockages before they lead to extensive damage. However, the best solution depends on the condition of the pipe and the severity of the tree root invasion.
Understanding why roots enter sewer lines, recognizing the warning signs, and knowing what sewer cleaning methods work can help Salt Lake City homeowners protect their plumbing systems and avoid costly repairs.
Why Are Tree Roots Drawn to Sewer Lines?
Tree roots naturally grow toward sources of moisture. Your sewer line carries wastewater away from your home, making the surrounding soil and pipe joints particularly attractive to thirsty roots.
Even a sewer pipe that appears to be functioning normally may attract roots if there are small weaknesses or openings.
Moisture Can Attract Roots
Tree roots are highly effective at locating moisture underground. Older pipes, loose connections, and tiny cracks may allow moisture to escape into the surrounding soil.
Over time, nearby roots can grow toward that moisture source and eventually find their way into the sewer line.
Wastewater Contains Nutrients
Sewer lines transport wastewater containing organic material and nutrients. If roots discover an opening in the pipe, the moisture and nutrients inside can encourage further growth.
What begins as a few thin roots entering through a small crack can eventually become a dense mass inside the pipe.
Small Openings Can Become Major Problems
Roots do not necessarily break through a perfectly sealed pipe. In many cases, they take advantage of an existing weakness, such as:
Cracked or deteriorating pipes
Loose pipe joints
Damaged pipe connections
Aging sewer materials
Shifting soil around underground plumbing
Previous pipe damage
Once tree roots enter the sewer line, they can expand and worsen the original damage.
How Tree Roots Damage Your Sewer System
Tree roots may grow slowly, but the damage they cause can become severe over time. The longer the problem remains untreated, the greater the risk of blockages, broken pipes, and sewage backups.
Cracks and Blockages
Roots can enter through small openings and continue growing inside the pipe. As they spread, they create a web-like obstruction that catches waste and debris.
This can lead to:
Slow drains throughout the home
Frequent toilet clogs
Gurgling sounds from drains
Complete blockage of the main sewer line
A blockage caused by tree roots can affect multiple plumbing fixtures because the main sewer line connects the plumbing throughout your home.
Increased Pressure Inside the Pipe
When wastewater cannot move freely through the sewer line, pressure can build behind the blockage. This added pressure can worsen existing cracks or weaknesses.
As a result, a relatively small root intrusion can eventually contribute to more significant pipe damage.
Broken or Collapsed Sewer Pipes
In severe situations, roots and surrounding soil movement can contribute to major structural damage. Older or deteriorating pipes may crack, separate, or collapse.
A damaged sewer line may require more than routine sewer cleaning. Depending on its condition, professional sewer line repair or replacement could be necessary.
The consequences of a severely damaged pipe can include:
Extensive excavation
Damage to landscaping
Sewage leaks
Recurring blockages
Costly pipe replacement
Potential health and sanitation concerns
That is why identifying tree root problems early is so important.
Warning Signs of Tree Root Invasion
Tree roots do not usually cause a sudden plumbing problem overnight. In many cases, homeowners notice smaller warning signs before a complete blockage occurs.
If several of the following problems occur, it may be time to schedule a professional sewer inspection.
1. Slow Drains Throughout the Home
One slow sink may simply indicate a localized clog. However, when multiple drains throughout the home become slow, the problem could be deeper in the plumbing system.
A blockage in the main sewer line can affect:
Toilets
Showers
Bathtubs
Bathroom sinks
Kitchen sinks
Floor drains
Slow drainage affecting multiple fixtures should not be ignored.
2. Frequent Sewage Backups
Repeated backups are one of the clearest signs of a serious sewer line problem. If plunging or basic drain cleaning only provides temporary relief, tree roots or another obstruction may be blocking the main sewer line.
Sewage backups can expose your home to contaminated wastewater and should be addressed promptly.
3. Gurgling Sounds From Drains or Toilets
Gurgling noises can occur when air becomes trapped because wastewater cannot move properly through the sewer system.
You may hear these sounds when:
Flushing the toilet
Running the washing machine
Draining a bathtub
Using a sink
While gurgling does not always mean tree roots are the cause, it can indicate a developing blockage that requires professional attention.
4. Sewage Odors
Persistent sewer odors inside or outside the home may indicate a problem with the sewer system.
Damaged pipes or root intrusion can allow sewer gases to escape. If you notice unexplained sewage smells, it is best to schedule an inspection rather than simply masking the odor.
5. Soggy or Unusually Green Areas in the Yard
A damaged underground sewer line may leak wastewater into the surrounding soil. This can create soft, wet, or unusually lush areas in the yard.
Because underground moisture can come from several sources, a professional inspection is the best way to determine whether the sewer line is involved.
What Sewer Cleaning Works for Tree Roots?
Not every drain cleaning method is effective against tree roots. The best approach depends on how much root growth is present and whether the pipe itself has been damaged.
A professional plumber may use a combination of inspection and cleaning methods to restore proper flow.
Video Camera Inspection Comes First
Before choosing a cleaning method, a plumber may perform a sewer camera inspection.
A small waterproof camera is sent through the sewer line to identify:
The location of the blockage
The extent of the tree root intrusion
Cracks or damaged pipe sections
Pipe offsets or separated joints
Collapsed or severely deteriorated areas
This inspection helps determine whether sewer cleaning is sufficient or whether the pipe needs repair.
Mechanical Root Cutting
For some tree root blockages, plumbers can use specialized cutting equipment to remove roots from inside the sewer pipe.
Mechanical cutting can break apart root masses and reopen the line, allowing wastewater to flow again.
However, removing the roots does not automatically repair the opening that allowed them to enter. If the pipe remains cracked or separated, tree roots may eventually grow back.
Hydro Jetting for Root and Debris Removal
Hydro jetting is another professional sewer cleaning method that may be used for certain root-related blockages.
This process uses highly pressurized water to clean the inside of the sewer pipe and remove built-up debris.
Hydro jetting can help clear materials such as:
Grease buildup
Sludge
Soap residue
Organic debris
Certain root remnants
Because sewer pipes can vary significantly in age and condition, a professional inspection is important before hydro jetting. A severely damaged or deteriorated pipe may require repair before high-pressure cleaning is appropriate.
When Cleaning Is Not Enough
Sewer cleaning can restore flow, but it cannot always solve the underlying cause of tree root intrusion.
If a camera inspection reveals significant cracks, breaks, or a collapsed pipe, repair or replacement may be necessary.
Addressing the damaged section can help reduce the chance of recurring tree root problems and protect the long-term condition of your sewer system.
Don't Reach for Chemical Drain Cleaners
When a drain backs up, it may be tempting to reach for a chemical drain cleaner. However, chemical products are generally not a reliable solution for tree root problems in a main sewer line.
They may also create additional concerns.
Why Chemical Cleaners Can Be a Bad Idea
Harsh chemical products can:
Damage certain types of pipes
Fail to remove significant root growth
Provide only temporary relief
Create safety risks when mixed with other chemicals
Complicate professional plumbing work later
Tree roots are a physical obstruction inside the sewer line. They typically require professional equipment and an accurate diagnosis rather than a bottle of chemical cleaner.
If you suspect a blockage in your main sewer line, calling a licensed plumber is the safer and more effective approach.
Why Sewer Line Cleanouts Are Important
Many homes have a sewer cleanout, which provides an access point to the main sewer line.
This access can allow plumbers to inspect and clean the sewer system more efficiently without accessing plumbing fixtures inside the home.
How a Sewer Cleanout Helps
A sewer cleanout can make it easier to:
Inspect the main sewer line
Insert a sewer camera
Remove blockages
Perform professional sewer cleaning
Access the pipe for maintenance
If your home has recurring sewer problems, knowing where the cleanout is located can help when a plumbing emergency occurs.
How to Prevent Tree Root Problems
You cannot stop trees from growing roots, but you can take steps to reduce the risk of root-related sewer problems.
Plant Trees Carefully
Before planting a tree, consider where your underground utilities and sewer line are located.
Choosing an appropriate location can help reduce the risk of roots reaching vulnerable pipes in the future.
Consider the Tree's Root System
Different tree species have different root growth patterns. Before planting near underground plumbing, research the expected size and behavior of the tree's root system.
A landscaping professional or plumber may also help you understand potential concerns around existing sewer lines.
Schedule Regular Sewer Inspections
Older homes or properties with mature trees may benefit from periodic sewer camera inspections.
A camera inspection can identify small root intrusions before they become large enough to cause a complete blockage.
Address Small Problems Early
Recurring slow drains, gurgling, or occasional backups may seem like minor inconveniences. However, waiting for the problem to become severe can lead to more expensive repairs.
Early sewer cleaning may help prevent a small tree root intrusion from turning into a major plumbing emergency.
When Should You Call a Professional Plumber?
A professional inspection is recommended if you experience repeated drainage problems or suspect that tree roots have entered your sewer system.
You should contact a plumber when you notice:
Multiple slow drains
Frequent clogs
Sewage backing up into fixtures
Gurgling toilets or drains
Persistent sewer odors
Wet or soggy areas near the sewer line
Recurring blockages after previous drain cleaning
Professional equipment can identify the source of the problem instead of simply treating the symptoms.
