How to Get Rid of Roots in My Sewer Line: A Step-by-Step Guide?
Tree roots typically infiltrate sewer lines through cracks, joints, or weak areas in the pipe material, especially in older clay or cast-iron pipes. Roots naturally seek moisture, and once they find an entry point, they grow inside the pipes, causing blockages, reduced flow, and potential pipe damage. Common signs of root intrusion include slow drainage, gurgling sounds, and unpleasant odors from drains, which worsen over time.

For minor root blockages, DIY methods like chemical root killers (e.g., copper sulfate) and mechanical tools like augers or root cutters can provide temporary relief. Copper sulfate dissolves the roots within the pipe, while augers and root cutters use rotating blades or chains to physically cut through and remove the roots. Flushing the line afterward helps clear remaining debris, improving drainage.
However, when root intrusion is severe or when damage to the pipes is present, professional intervention may be required. Methods like hydro jetting, which uses high-pressure water (up to 4,000 psi) to clear blockages, or pipe inspections with cameras, are ideal for addressing tougher problems. In cases of extensive damage, professional plumbers may excavate and replace the pipe with materials like PVC or ABS for a lasting solution.
Things to Consider Before Starting the Process
Before removing roots from your sewer line, it is important to assess the severity of the blockage and the condition of your pipes. Simple issues can often be resolved with DIY methods, but more complex problems may require professional intervention.

Root Intrusion and Sewer Line Damage
Root intrusion is a common and significant issue for homeowners, as tree roots naturally seek out moisture and can easily infiltrate sewer lines. When tree roots find cracks or joints in sewer pipes, they can grow inside the pipes, blocking the flow of waste and causing damage to the pipes themselves. Over time, this can lead to backups, slow drainage, and costly repairs. Understanding the causes and effects of root intrusion is crucial for preventing and addressing this issue.
Causes of Root Intrusion in Sewer Lines
Root intrusion typically occurs when trees or plants grow near sewer lines, seeking water through cracks or damaged joints. This is particularly common in older plumbing systems with weak or deteriorating pipes.
Key causes of rot intrusion in sewer lines include:
- Cracks in pipes: Over time, pipes can develop cracks due to age, shifting ground, or corrosion, allowing roots to infiltrate.
- Loose joints: Poorly sealed or broken pipe joints provide an entry point for roots.
- Old plumbing: Older homes with clay, cast iron, or other outdated materials are more susceptible to root intrusion.
- Aggressive tree roots: Large, invasive tree species like willows, maples, and oaks have aggressive root systems that are more likely to invade sewer lines.
Effects of Tree Roots on Sewer Lines
When roots invade sewer lines, they can cause severe damage and disrupt the flow of waste. As roots grow inside the pipes, they obstruct drainage, cause backups, and weaken the pipe structure.
Below are the primary effects of root intrusion on sewer lines:
- Blockages and clogs: Roots obstruct the flow of waste, leading to slow drainage and frequent backups.
- Cracking and pipe damage: As roots grow, they exert pressure on the pipes, causing cracks and fractures that can weaken the structure.
- Foul odors: Blockages caused by roots can lead to waste buildup, causing unpleasant odors to emanate from drains.
- Costly repairs: If left unchecked, root intrusion can result in significant damage, requiring costly repairs, excavation, or full pipe replacement.
Preventing Tree Roots from Growing into Sewer Lines
To effectively prevent tree roots from infiltrating sewer lines, implement root barriers, use preventative chemical treatments, plant trees with consideration for placement, and schedule regular maintenance and inspections. These proactive measures significantly reduce the likelihood of root intrusion and ensure long-term protection for your plumbing system.
Root Barriers Installation
Root barriers are physical structures designed to block tree roots from penetrating sewer lines. Made from materials like plastic, metal, or geotextile fabric, these barriers provide a durable defense by preventing roots from reaching and infiltrating the pipes. Installing root barriers at the time of pipe replacement or when planting trees is the most effective way to protect your sewer system.
Here is how to install root barriers effectively:
- Locate the tree’s root system or the sewer line path.
- Dig a 2 to 3-foot deep trench wide enough for the barrier.
- Choose the appropriate material based on your needs. Geotextile fabric is typically used for larger areas, while plastic or metal barriers are ideal for smaller sections.
