Trees are an important part of a neighborhood, but their roots naturally seek moisture. If a sewer line has a small crack, loose joint, or other opening, roots can grow toward that moisture and eventually enter the pipe.
Roots usually take advantage of an existing opening
Healthy roots do not typically break through a sound sewer pipe from nowhere. More often, they find a weak joint, crack, or gap and grow into the line. Once inside, they can expand and catch toilet paper, grease, wipes, and other debris.
Common warning signs
Slow drains throughout the house, recurring clogs, gurgling toilets, or backups at a basement drain can all be signs of a problem in the building sewer. Tree-root intrusion is only one possible cause, so guessing is not the best approach.
A sewer camera can show what is actually happening
Televising the line allows a technician to inspect the inside of the pipe. A camera can reveal root intrusion, cracks, offset joints, standing water, collapsed sections, and other defects that cannot be diagnosed from the surface. Learn more about sewer televising.
Treatment depends on the condition of the pipe
Roots can sometimes be cut or removed to restore flow, but that does not repair the opening that allowed them into the pipe. Depending on the age and condition of the line, a more permanent solution may involve repairing a section, replacing the line, or using a lining method where appropriate.
Do not ignore repeat problems
If a line has to be cleared again and again, that is a sign that the underlying problem may not have been corrected. A camera inspection can help determine whether the issue is roots, a damaged pipe, poor alignment, or something else.
If you are unsure whether a sewer problem is in your private line or the public system, the Ben Davis Conservancy District can help you understand where to begin.
