Root intrusion is a common problem faced by many sewer systems, particularly those that incorporate sections of PVC (polyvinyl chloride) piping. It occurs when tree or shrub roots grow into the joints of sewer pipes, seeking water and nutrients. These roots can eventually cause blockages, reduced flow, and sometimes even complete sewer line failure.

PVC pipes are popular in sewer systems due to their durability, ease of installation, and resistance to corrosion. However, when these pipes are not properly glued at the joints or segments, they become susceptible to root intrusion. The adhesive used in PVC piping creates a tight seal that keeps roots out, but if this step is skipped or improperly executed, small openings at the joints can exist, providing an easy entry point for roots.

Roots naturally gravitate toward sources of moisture and nutrients, both of which are plentiful in sewer lines. Tiny hair-like roots can detect the presence of water and nutrients escaping from unsealed or improperly sealed joints. Once they make their way into these cracks or gaps, they can grow into larger roots and exert considerable pressure on the pipes. Over time, this pressure can cause the pipes to break or become misaligned.

The primary consequence of root intrusion is blockage. As roots grow and expand within the sewer line, they can trap solids and disrupt the flow of wastewater. This can result in slow drains, backups, and even sewage overflow into homes or onto the property.

Another complication is the potential damage to the sewer pipes themselves. Strong, growing roots can crack or break PVC pipes, necessitating costly repairs or replacement. Furthermore, a compromised sewer line can lead to soil contamination, as sewage leaks into the ground, posing health risks and environmental concerns.

Homeowners and property managers should be vigilant for signs of root intrusion, such as slow drains, gurgling noises from plumbing fixtures, and unexplained wet spots in the yard. If root intrusion is suspected, a plumbing professional can use video inspection tools to confirm the issue.

Once detected, addressing root intrusion involves clearing the roots and repairing the pipes. Methods such as hydro jetting or root cutting can remove the obstruction, but it is also crucial to fix the unglued joints. Pipe relining or replacing the affected segments may be necessary to prevent recurrence.

In prevention, care should be taken when planting trees and shrubs near sewer lines. Choose slow-growing, less invasive species, and place them a safe distance from the pipes. Regular maintenance and inspections can also help catch potential problems before they turn into major repairs.

Unglued PVC sewer line segments are an open invitation for root intrusion. To maintain a functional and efficient sewer system, proper installation and regular maintenance are essential. A proactive approach can save property owners considerable time, money, and inconvenience by avoiding the severe consequences of root intrusion into the sewer lines.
