What to Do About Tree Roots in Your Sewer Line

Posted by Zak and Jay

Struggling with tree roots in sewer line backups? Learn how to kill tree roots in sewer line systems and what dissolves tree roots in sewer pipes effectively. Trust PlumbWize for professional root removal and expert sewer line repair across Ontario.

For many Ontario homeowners, the backyard is a sanctuary anchored by beautiful, mature trees. However, beneath that lush grass lies a threat to your sewer system.

Tree roots are naturally drawn to moisture and nutrients, which your sewer line provides. Over time, tiny “feeler” roots from expansive root systems find even the smallest loose joint or crack in a pipe, eventually leading to a significant sewer line tree roots problem

If you suspect your sewer line pipes are under attack, here’s what you need to know about managing root intrusion and protecting your property.

Common Warning Signs of Roots in Sewer Pipes

If you are noticing these symptoms, you may have roots in sewer pipes causing backups.

  • gurgling noises from your toilet
  • slow-draining sinks
  • sewer backups in your basement 

You might also notice sudden, unexplained patches of extra-green grass in your yard where the roots grow more aggressively due to the extra fertilizer. 

How Do I Know if I Have Roots in My Sewer Line?

The most reliable way to confirm root growth is through a sewer camera inspection. A professional plumber will insert a high-definition camera into the main sewer line to inspect the pipe’s interior. 

This allows the property owner to see the exact location of the root intrusion and determine if it has caused significant damage to the sewer lateral.

What Dissolves Tree Roots in Sewer Lines?

A few common DIY home remedies can help dissolve tree roots in sewer lines:

  • Copper Sulfate: This traditional root killer creates a toxic zone around the pipe, discouraging root growth. However, copper sulfate can be harmful to the environment and may be illegal in some Ontario municipalities.
  • Rock Salt: This can dehydrate and kill roots, but is often a temporary fix. It can harm the surrounding soil if overused.
  • Foaming Herbicides: These are designed to kill tree roots that hang from the top of the sewer line pipes, which liquid chemicals might miss.

Though these chemicals can temporarily remove tree roots, they don’t address the underlying sewer issues. If roots have intruded, there’s likely a leak or loose joint that needs professional repair.

How to Kill Sewer Line Tree Roots: Professional Solutions

To effectively remove tree roots and prevent a total blockage, manual or mechanical intervention is usually required. PlumbWize offers several advanced methods:

  1. Mechanical Augering and Root Saws: A drain snake equipped with root saws can cut through a complete blockage, restoring water flow.
  2. Hydro Jetting: This process uses high pressure and warm water to scour sewer lines clean. It is one of the best ways to remove roots alongside other debris, such as toilet paper.
  3. Pipe Repair and Relining: For damaged clay pipes or older cast-iron lines, we may suggest trenchless repair. This involves inserting a resin-coated liner into the existing pipe, creating a new, seamless “pipe within a pipe” that is root-resistant.

Preventing Tree Roots from Returning

To prevent tree roots from invading your sewer system, conduct regular main line inspections, especially if large trees with invasive root systems are near the sewer lateral. Replacing old clay pipes with PVC pipes can also prevent root growth, as PVC pipes have fewer joints for roots to exploit. 

FAQs About Tree Roots in Sewer Line

What is the best way to kill tree roots in a sewer line?

For temporary DIY relief, foaming root killer is effective because it expands to coat the entire pipe interior. However, professional hydro jetting is the best long-term solution for killing tree roots and clearing debris.

How much does it cost to remove roots from drains?

+

Professional tree root removal in Ontario generally ranges from $300 to $1,100, depending on the severity. Sewer camera inspection fees often add an additional $100 to $300 to the total bill.

Will bleach or vinegar kill roots in a sewer line?

+

While bleach may kill roots on contact, it’s often too diluted by the time it reaches the main sewer line to be effective. It can also damage your sewer system and the surrounding soil.
