What is one of the primary causes of sewer backups?

One of the primary causes of sewer backups is tree root intrusion. Tree roots naturally seek water and nutrients, and as they grow, they can infiltrate underground sewer lines. When roots penetrate the pipes, they can obstruct the flow of wastewater, leading to blockages. This interference often causes sewage to back up through the system, resulting in overflows and potential damage.

Understanding tree root behavior is crucial for utility management and plumbing, as it emphasizes the importance of proper landscaping and sewer line maintenance. Owners must be aware of the species of trees planted near sewer lines to mitigate this risk, as certain trees are more notorious for root invasiveness. By recognizing the threat posed by tree roots, plumbers can recommend preventive measures, such as regular inspections and root barriers, to protect sewer systems from potential backups.
