Can certain tree species cause sewer problems more often than others?

Yes. Trees with aggressive, fast-growing root systems—such as willow, maple, and poplar—are more likely to invade sewer lines.

Are modern sewer pipes less vulnerable to root intrusion?

Modern materials like PVC are more resistant, but poor joints or shifting soil can still create entry points.

They don’t grow faster biologically, but constant moisture and nutrients allow them to thrive once inside.

Some products can slow root growth temporarily, but they don’t fix structural damage and should only be used under professional guidance.
