How to Get Rid of Roots in Your Sewer Pipes?

Tree roots in sewer pipes are more common than most homeowners think. If you’re dealing with slow drains, frequent backups, or bad smells, roots could be the hidden cause.

The good news? You can remove them, and more importantly, prevent them from coming back.

In this guide, we’ll walk you through:

• Why roots grow into sewer lines
• How to remove them safely
• The role of a sewer line inspection
• Proven ways to prevent root growth in sewer line systems

Everything is explained in simple, clear terms so you can take action with confidence.

Why Do Tree Roots Grow Into Sewer Pipes?

Tree roots naturally seek out moisture and nutrients. Your sewer line provides both.

Even a tiny crack in a pipe can release vapor or water. Roots sense this and slowly grow toward it. Once inside, they expand and block the pipe.

Common Causes of Root Intrusion:

• Aging or cracked pipes
• Loose pipe joints
• Clay or cast iron sewer lines
• Poor installation or shifting soil

Over time, the roots get thicker. They trap debris like grease and toilet paper, leading to full blockages.

Signs You Have Roots in Your Sewer Line

Before you dig anything up, look for these warning signs:

1. Slow Drains Throughout the House

If multiple drains are slow, the issue is likely in your main sewer line, not just one pipe.

2. Frequent Backups

Toilets or sinks backing up often? Roots may be restricting flow.

3. Gurgling Sounds

Air trapped by roots can cause bubbling or gurgling noises in drains.

4. Bad Odors

Blocked pipes can release sewage smells inside or outside your home.

5. Extra Green Patches in Yard

Roots feeding on wastewater may cause unusually lush grass above the pipe.

Start With a Sewer Line Inspection

Before fixing the problem, you need to confirm it.

A sewer line inspection uses a small camera inserted into your pipes. It shows:

• Where the roots are
• How severe the blockage is
• Whether the pipe is damaged

Why This Matters:

• Prevents guesswork
• Saves time and money
• Helps choose the right solution

Professional inspectors can give you a clear diagnosis in one visit.

How to Get Rid of Roots in Your Sewer Pipes

Once you confirm roots are the issue, you have several effective options.

1. Mechanical Root Cutting

This is one of the most common methods.

A special cutting tool is inserted into the pipe. It spins and cuts through roots.

Best for:

• Thick root masses
• Immediate blockage removal

Pros:

• Fast results
• Clears major clogs

Cons:

• Roots can grow back if not treated

2. Hydro Jetting

Hydro jetting is a method plumbers may use to clear sewer line blockages after they are identified through sewer inspection.

Best for:

• Light to moderate root growth
• Cleaning pipe walls

Pros:

• Thorough cleaning
• Removes grease and buildup

Cons:

• May not remove very thick roots

3. Chemical Root Killers (Use Carefully)

Certain products can kill roots inside pipes without harming the tree immediately.

Best for:

• Preventing regrowth after cutting

Pros:

• Easy to apply
• Slows root return

Cons:

• Must be used correctly
• Not a permanent fix

4. Pipe Repair or Replacement

If serious damage is found, a licensed plumber may need to perform repair or replacement.

Options include:

• Spot repair
• Pipe relining
• Full replacement

Best for:

• Cracked or collapsed pipes

Pros:

• Long-term solution
• Stops root entry

Cons:

• More involved process

How to Prevent Root Growth in Sewer Line Systems

Removing roots is only half the job. Prevention is key.

Here’s how to stop the problem from coming back.

1. Schedule Regular Sewer Line Inspection

Routine sewer scope inspections catch small issues before they become major problems.

Tip:

Inspect every 1–2 years, especially if you have older pipes or large trees nearby.

2. Avoid Planting Trees Near Sewer Lines

Roots can spread far beyond the visible tree.

Safe distance:

• At least 10–20 feet from sewer lines

Choose trees with less aggressive root systems.

3. Upgrade Old Pipes

Older materials like clay or cast iron are more vulnerable.

Modern options like PVC are:

• More durable
• Resistant to root intrusion

4. Use Root Barriers

Physical barriers can block roots from reaching your sewer line.

These are installed underground between trees and pipes.

5. Apply Preventive Treatments

After removing roots, apply root inhibitors to slow regrowth.

This is especially useful if you cannot remove nearby trees.

6. Fix Leaks Quickly

Even small leaks attract roots.

If you notice:

• Wet spots in yard
• Sewer smells
• Sudden drain issues

Get them checked immediately.

DIY vs. Professional Help: What’s Best?

Some homeowners try DIY solutions, but sewer issues can get complicated fast.

DIY May Work If:

• The blockage is minor
• You have proper tools
• No pipe damage is present

Call a Professional If:

• Roots keep coming back
• Multiple drains are affected
• You suspect pipe damage
• You need a sewer line inspection

Professionals have the right equipment and experience to fix the problem safely.

Long-Term Risks of Ignoring Root Intrusion

If left untreated, roots can cause serious damage:

• Complete pipe blockage
• Sewage backups inside your home
• Pipe collapse
• Costly repairs

Early action saves you time, stress, and money.

Expert Tips From the Field

After years of home inspection experience, here are a few practical insights:

• Don’t wait for a full backup — early signs matter
• Combine removal + prevention — cutting alone isn’t enough
• Keep records of inspections — helps track recurring issues
• Work with certified inspectors — accuracy matters

A proactive approach always beats emergency repairs.
