How to Get Rid of Tree Roots in Plumbing Fast & Safely

If your drains are slow, gurgling, or backing up—and you’ve got trees nearby—you might be dealing with a hidden invader: tree roots in your plumbing. It’s more common than you think, especially in older homes with clay or cast-iron sewer lines. Left unchecked, these roots can cause serious blockages, leaks, or even pipe collapse. The good news? You can stop them. In this guide, we’ll walk you through exactly how to get rid of tree roots in plumbing—safely, effectively, and affordably.

Why Do Tree Roots Invade Plumbing Pipes?

Tree roots seek moisture, oxygen, and nutrients—making your sewer line a prime target. Even tiny cracks or loose joints in underground pipes can let in water vapor, which roots detect from up to 100 feet away, according to the International Society of Arboriculture.

Older pipe materials like clay, cast iron, or Orangeburg are especially vulnerable. Modern PVC is more resistant but not immune—especially if improperly installed.

💡 Fact: A single mature tree can send roots over 30 feet horizontally. If your sewer line runs near a large tree, intrusion is almost inevitable over time.

Signs You Have Tree Roots in Your Pipes

Don’t wait for a full-blown sewage backup. Watch for these early warning signs:

• Slow drains in multiple fixtures (not just one sink)
• Gurgling sounds from toilets or drains
• Foul odors coming from drains or yard
• Sewage backups after heavy rain
• Lush green patches in your lawn (a sign of leaking nutrients)

If you notice two or more of these, it’s time to investigate further—ideally with a professional sewer camera inspection.

How to Get Rid of Tree Roots in Plumbing: 5 Proven Methods

1. Mechanical Root Removal (Augering/Rooting)

This is the most common first-line defense. A plumber uses a powered drain auger (also called a rooter) with a cutting blade to slice through roots inside the pipe.

• Best for: Moderate root intrusions
• Effectiveness: Immediate clearing, but roots grow back in 6–18 months
• Cost: $150–$400 (DIY augers start at $50, but limited reach)

⚠️ Caution: Aggressive augering can damage old or fragile pipes. Always use a professional for sewer lines.

2. Hydro Jetting: High-Pressure Water Cleaning

Hydro jetting uses 3,000–4,000 PSI water pressure to blast away roots, sludge, and buildup from pipe walls.

• Best for: Severe blockages or preventative maintenance
• Effectiveness: Cleans 95%+ of debris; smoother pipe = slower regrowth
• Cost: $350–$600

✅ Pro Tip: Combine hydro jetting with a camera inspection to confirm full clearance.

3. Chemical Root Killers (Foaming or Copper-Based)

These products kill roots on contact and prevent regrowth for several months.

• Common active ingredients: Dichlobenil (foaming) or copper sulfate
• Application: Pour into toilet or cleanout; let sit 6–8 hours
• Effectiveness: Kills small-to-medium roots; won’t clear heavy blockages

🌱 Eco Note: Copper sulfate can harm soil and waterways. Use sparingly and check local regulations. Learn more about copper sulfate environmental impact .

4. Pipe Lining (Trenchless Repair)

For recurring root problems, cured-in-place pipe (CIPP) lining seals cracks and creates a new, seamless pipe inside the old one—without digging.

• Best for: Pipes with multiple cracks or frequent root returns
• Lifespan: 50+ years
• Cost: $80–$250 per foot (vs. $200+/ft for traditional excavation)

💬 Expert Insight: “Trenchless lining is the #1 solution we recommend for homeowners tired of root callbacks,” says Maria Lopez, licensed plumber with 18 years of experience in Atlanta.

5. Complete Pipe Replacement

If your sewer line is collapsed or beyond repair, full replacement may be necessary—especially if you have clay or Orangeburg pipes over 50 years old.

• Traditional dig: Invasive but thorough
• Pipe bursting: Trenchless method that replaces old pipe with new HDPE

Preventing Future Root Intrusion: 4 Smart Strategies

1. Plant Trees Strategically
   Keep water-loving trees (willows, poplars, maples) at least 30 feet from sewer lines.
2. Install Root Barriers
   Physical barriers (plastic or fabric) can deflect roots. Place 2–3 feet deep along the pipe route.
3. Schedule Annual Inspections
   A $200 camera check can catch small cracks before roots exploit them.
4. Use Enzyme Drain Cleaners Monthly
   Unlike harsh chemicals, enzyme cleaners break down organic buildup that attracts roots—safely.

DIY vs. Professional Help: When to Call a Plumber?

🚨 Never ignore a sewer backup. It poses health risks and can cause thousands in water damage.

FAQ: Tree Roots in Plumbing

Q1: Can tree roots break through PVC pipes?

A: Yes—but it’s rare. PVC is much more resistant than clay or cast iron. Roots usually enter through poorly sealed joints or existing damage, not by cracking the pipe itself.

Q2: How long does it take for roots to grow back after removal?

A: Typically 6 to 18 months, depending on tree species, soil moisture, and pipe condition. Foaming root killers can extend this to 2+ years.

Q3: Will bleach kill tree roots in sewer lines?

A: No. Bleach may kill surface bacteria but won’t penetrate or kill roots. It can even corrode pipes and harm septic systems.

Q4: Can I use rock salt to kill roots?

A: Rock salt (sodium chloride) can dehydrate small roots, but it’s not recommended. It damages soil, harms trees, and offers only temporary relief.

Q5: Does homeowners insurance cover root damage?

A: Usually no—most policies exclude “gradual damage” like root intrusion. However, some cover sudden backups if you have a sewer backup endorsement.

Q6: How much does root removal cost on average?

A: Most homeowners pay $200–$600 for mechanical or hydro jetting removal. Trenchless repair ranges from $4,000–$12,000, depending on length and location.

Conclusion

Dealing with tree roots in plumbing is stressful—but entirely manageable with the right approach. Whether you opt for a quick chemical treatment or invest in a long-term trenchless solution, acting fast can save you from costly repairs and health hazards.

✅ Key Takeaways:

• Early detection prevents major damage
• Hydro jetting + camera inspection = gold standard
• Prevention is cheaper than replacement
