Can root intrusion damage a sewer pipe?

Yes, root intrusion can widen cracks and separate pipe joints as roots grow. Continued entry also leaves space for soil to move into the line.

How can a plumber confirm root intrusion?

A sewer camera can show roots inside the pipe and identify the entry point. The inspection can also reveal breaks, open joints, or other defects.

Will clearing roots permanently fix the sewer line?

Clearing roots can restore flow for a time, but it does not repair the opening that allowed them inside. A damaged section may need sewer line repair.

Glossary

What Is Root Intrusion?

Root Intrusion is a sewer line problem where tree or plant roots enter through small cracks, loose joints, or damaged pipe sections. The roots grow inside the line and catch waste, grease, and paper. This buildup can restrict flow, cause repeated backups, and worsen pipe damage as the roots expand.

Quick Facts About Root Intrusion

Key Takeaways About Root Intrusion

Roots enter through cracks, gaps, or loose pipe joints.

How Root Intrusion Works

Root Intrusion starts when roots find moisture around a damaged sewer pipe. Small roots enter through a crack or loose joint, then grow inside the line. As the root mass expands, it catches paper, grease, and other waste.

A sewer camera can show where roots enter and how much of the passage is blocked. The inspection may also reveal separated joints, broken sections, or a sag in the pipe. A drain auger can clear some growth, while hydro jetting can wash away more buildup. These methods may not correct the damaged pipe that allowed roots inside.

How It Relates to Sewer Line Repair

Sewer line repair addresses the damaged section that permits root entry. The right method depends on the pipe material, damage location, access, and condition of the surrounding line.

Expert Note

Root Intrusion in Practice: A Real-World Example

A home may have slow drains that improve briefly after clearing, then back up again. A sewer camera can show roots entering through a cracked section of the lateral, where they collect waste and restrict flow.
