How to Remove Roots from a Sewer Line

Tree roots infiltrating your sewer line can cause significant blockages, leading to slow drainage, unpleasant odours, and potentially costly repairs. If left untreated, these roots can grow inside your pipes, causing extensive damage. 

Fortunately, there are effective ways to remove roots from your sewer line and prevent them from coming back. In this guide, we’ll walk you through the best methods to tackle this issue and keep your plumbing system in top condition.

1. Identify the Problem

Before you begin the removal process, it’s crucial to confirm that roots are the cause of your plumbing issues. 

Here’s how to do it:

• Look for Signs of Root Intrusion: Common indicators include slow-draining sinks or toilets, gurgling noises, and foul odors coming from your drains. If multiple drains are affected, it’s likely a sign that roots have invaded your sewer line.
• Use a Sewer Camera: A professional plumber can insert a CCTV camera into your sewer line to visually confirm the presence of roots. This inspection helps pinpoint the exact location and severity of the intrusion, guiding the next steps in the removal process.

2. Mechanical Removal

Once you’ve identified the root problem, mechanical removal is often the first line of defense. This method physically cuts through and removes the roots blocking your pipes.

• Drain Snake (Root Cutter Bit): You can rent a heavy-duty drain snake equipped with a root cutter bit, typically 5/8" or 3/4" in diameter. Here’s how to use it:
  • Insert the Snake: Start by using an arrowhead-shaped bit to punch through the clog. Move the snake back and forth to break up the roots.
  • Switch to a Side Cutter Bit: Once the initial blockage is cleared, use a side cutter bit to remove smaller roots and clean the pipe more thoroughly.
• Hydro Jetting: For larger or more stubborn root intrusions, hydro jetting is highly effective. This technique uses high-pressure water to blast away roots and debris, leaving your pipes clear. It’s especially useful for pipes that are difficult to access with a snake.

3. Chemical Treatments

After mechanically removing the roots, chemical treatments can help prevent regrowth and keep your sewer line clear.

• Copper Sulfate: This chemical is effective at killing roots, but it should be used with caution as it can be toxic and may be restricted in some areas. To use, pour about half a cup into your toilet and flush it down. The copper sulfate will kill the roots on contact.
• Foaming Root Killers: Products like RootX are designed to foam up when mixed with water, allowing the active ingredients to coat the inside of your pipes. The foam reaches all sides of the pipe, effectively killing any remaining roots and preventing regrowth.
• Rock Salt: A less toxic option is to use rock salt, which dehydrates and kills roots. Pour about 2 pounds of rock salt into your toilet, flushing half a pound at a time, and let it sit overnight before flushing with water.

4. Preventive Measures

After clearing the roots, it’s important to take steps to prevent them from coming back.

• Regular Inspections: Schedule routine inspections every couple of years, especially if your property has a history of root intrusion. Early detection can save you from larger problems down the line.
• Tree Management: If you have trees near your sewer line, consider removing or trimming them to prevent roots from reaching your pipes. Installing root barriers can also help direct roots away from your plumbing system.

5. When to Call a Professional

While DIY methods can be effective for minor root intrusions, severe cases may require professional intervention. A licensed plumber has the expertise and tools necessary to handle significant blockages, including trenchless pipe repair methods like pipe relining, which can reinforce and protect your pipes from future root intrusions.
