How to Remove Tree Roots in Sewer Line

Tree roots invading sewer lines can lead to significant plumbing problems, including blockages, reduced water flow, and potential pipe damage. This issue is especially common in older systems where small cracks or joints in the pipes allow roots to infiltrate in search of water and nutrients. Addressing tree roots in sewer lines promptly is crucial to prevent costly repairs and avoid further damage to your plumbing system.

This guide on how to remove tree roots in sewer line will walk you through effective methods to identify, remove, and prevent tree root invasions.

Why Are Tree Roots a Problem in Sewer Lines?

Tree roots are constantly searching for moisture and nutrients, making sewer lines an attractive source. The intrusion of tree roots into sewer pipes can cause blockages that prevent the proper flow of wastewater and lead to backups or overflows. Additionally, as the roots grow inside the pipes, they can create cracks or breaks that allow dirt and debris to enter, leading to clogs and potential pipe damage.

You may notice signs of tree root invasion, such as slow drainage, gurgling sounds from your pipes, or foul smells coming from your drains. If left untreated, this issue can escalate and cause significant damage to your sewer line and even affect the plumbing in other parts of your home.

Needed Materials

Before attempting to remove tree roots from your sewer line, gather the necessary materials. This will ensure you have everything on hand and can complete the task efficiently.

Protective Gear:

Tree roots in sewer lines can be hazardous to handle, so it’s essential to have the proper protective gear. This includes gloves, safety glasses, and a face mask.

Plumbing Tools:

Having the right plumbing tools will make the removal process easier. Some necessary tools include:

• Drain Auger or Snake
• Hydro Jetter
• Root Saw or Cutter
• Pipe Wrench

Chemical Solutions:

Several chemical solutions on the market are designed to kill tree roots within sewer lines. These products contain copper sulfate or dichlobenil, which can be effective in killing roots and preventing regrowth.

8 Effective Methods on How to Remove Tree Roots in Sewer Line

Method 1: Use a Drain Auger or Snake

A drain auger or plumbing snake is one of the most effective tools for manually removing tree roots from a sewer line. This tool works by breaking up the roots and clearing the blockage to restore proper water flow. To use a drain auger or snake, insert it into the cleanout port of your sewer line and guide it toward the blockage.

Once you reach the obstruction, rotate the auger to cut through the roots. Be patient and work slowly to ensure the roots are thoroughly removed without damaging your pipes. After removing the roots, flush the line with water to clear out any remaining debris. Regular use of a drain auger can also help maintain your sewer line and prevent future blockages caused by root intrusions.

Method 2: Utilize a Hydro Jetter

A hydro jetter is a high-pressure water hose with a specialized nozzle designed to blast through and remove tree roots from sewer lines. This method is particularly effective for larger root masses or stubborn blockages. It’s essential to use caution when operating a hydro jetter, as the high pressure can cause damage to your pipes if not used correctly.

To use a hydro jetter, insert it into the cleanout port and slowly feed it through the pipes while spraying water at high pressure. The force of the water will break up and flush out any tree roots present in the line.

Method 3: Cut Roots With a Root Saw or Cutter

A root saw or cutter can be a useful tool for cutting and removing roots for smaller root intrusions. These tools are specifically designed to fit into sewer pipes and cut through tree roots without damaging the pipe itself.

To use a root saw or cutter, insert it into the cleanout port and carefully guide it toward the blockage while rotating it to cut through the roots. Afterward, flush the line with water to clear out any remaining debris.

Method 4: Apply Chemical Solutions 

Chemical solutions are an effective option for killing tree roots in sewer lines and preventing them from growing back. These products typically contain either copper sulfate or dichlobenil, which target tree roots without damaging your pipes. Before using chemical solutions, ensure that they are safe for your plumbing system and follow all manufacturer instructions. 

To apply a chemical solution, pour it into the drain or cleanout port of your sewer line as directed on the product packaging. The chemicals will travel through the pipes, killing roots on contact and creating a barrier that discourages regrowth. It’s important to allow the solution to sit for the recommended time to ensure it works effectively. Afterward, flush the line with plenty of water to clear out dead roots and any remaining chemicals.  

Method 5: Use a Foaming Root Killer

Foaming root killers are another chemical solution option for removing tree roots from sewer lines. These products contain specialized foaming agents that cling to the inside of pipes and seep into cracks and crevices, killing any roots present. They also create a protective barrier to prevent future root growth.

To use a foaming root killer, pour it directly into your drain or cleanout port as directed on the product packaging. The foam will expand and spread throughout the pipes, reaching deep into the sewer line where tree roots tend to grow.

Method 6: Hire a Professional Plumber

If you’re not comfortable attempting to remove tree roots from your sewer line yourself, or if the blockage and root intrusion are severe, it’s best to hire a professional plumber. These experts have the necessary tools and experience to effectively remove tree roots and prevent future intrusions.

Before hiring a plumber, be sure to do your research and choose a reputable company with positive reviews. It’s also essential to get estimates from multiple plumbers to ensure you’re getting the best price for the job.

Method 7: Install a Root Barrier

If tree roots are a recurring issue in your sewer line, consider installing a root barrier. These barriers are made of thick plastic or metal and are placed around your sewer line to create a physical barrier that prevents tree roots from growing into the pipes.

This method is best used as a preventative measure before any significant root intrusion occurs, but it can also be effective in stopping future root growth.

Method 8: Remove Trees Near Sewer Lines

In extreme cases where tree roots continue to cause problems, even after attempting other removal methods, removing trees near sewer lines may be necessary. This option should only be considered as a last resort, as removing trees can be expensive and may impact your property’s landscape.

If possible, try to remove the tree without disturbing its roots to prevent any potential damage to your sewer line. It’s also essential to consult with an arborist or professional landscaper before making this decision.

Following these methods on how to remove tree roots in sewer line can effectively remove tree roots from your sewer line and prevent future blockages. Be sure to regularly maintain your pipes and take preventative measures to avoid any root intrusions in the future. By staying proactive, you can keep your sewer line running smoothly and avoid costly repairs or replacements.
