How Tree Roots Can Damage Sewer Lines (and What to Do About It)
Tree roots are nature’s way of searching for water, unfortunately, that sometimes means they find your sewer line. Root intrusion is one of the most common causes of major drain blockages and sewer backups, especially in older homes with clay or cast iron pipes.
How Roots Invade Sewer Lines
Roots are naturally drawn to moisture and nutrients. If there’s even a small crack, loose joint, or pinhole in your sewer pipe, roots can find their way in. Once inside, they grow quickly, feeding off the water and waste flowing through the pipe.
Over time, roots can form dense mats that slow drainage, block the line completely, or even break the pipe apart.
Signs of Root Damage
You might not notice it right away, but there are telltale signs that tree roots are invading your sewer line:
- Frequent or recurring clogs in toilets, tubs, and sinks
- Slow drains throughout the home, not just one fixture
- Gurgling sounds or bubbles when flushing toilets
- Lush green patches in your yard over the sewer path (roots love the extra nutrients!)
- Sewage odors around drains or outdoors
If you see these symptoms, it’s time to act fast, root intrusion won’t go away on its own.
How Professionals Remove Tree Roots
Plumbers use specialized tools to locate and clear the blockage without digging up your yard unnecessarily.
- Video Camera Inspection:
A small waterproof camera is inserted into your sewer line to pinpoint the problem area. - Hydro Jetting or Root Cutting:
High-pressure water (hydro jetting) blasts away roots and buildup, while mechanical cutters slice through thicker obstructions. - Repair and Prevention:
If the pipe is cracked or damaged, trenchless repair or pipe replacement may be recommended to prevent future root intrusion.
Prevention Tips
- Avoid planting large trees near your sewer line (especially maples, willows, and poplars).
- Schedule annual sewer camera inspections if you live in an older home.
- Consider trenchless pipe lining, which seals cracks and prevents roots from entering again.
