Common Issues With Sewer Lines

Issues with sewer lines can take many forms, but all of them can lead to major damage if not dealt with quickly. We’ve outlined a few common issues we’ve seen time and again in the field.


When flushed items fail to flow through your sewer line properly, they can build up and eventually cause a blockage. So-called “flushable” items like single-use wipes, diapers, paper towels, and tissues often block up sewer lines and can lead to damage. Your sewer line will show signs of blockage long before a major event occurs. Slow drains, water draining from one fixture to another, and bubbling sounds in pipes are may be signs of a sewer blockage. If you notice any of these, give Best Plumbing a call immediately as it could be a sign of potential sewer failure.

Tree Root Damage

Trees are a staple of any yard, but they can do major damage to your sewer line. Tree roots will spread and grow to get the water they need, especially during the summer months. If these roots get near your sewer line, they can cause blockages or fully collapse the pipes over time. You can help prevent this by regularly watering your trees during warmer months and planting any new trees away from your sewer lines.

Pipe Deterioration

Deteriorating or corroding pipes are especially common in older homes.  Homes without a PVC-based sewer line are likelier to need a sewer line replacement. Sewer line integrity declines over decades, with iron or copper pipes needing to be replaced between every 30-50 years. It’s difficult to predict when problems will arise; regular inspections and maintenance are critical so you can get ahead of any issues.

In many cases, it will be cheaper in the long run to have your sewer lines replaced instead of repairing them, especially when it comes to tree root damage and pipe corrosion. While patchwork can help remediate the situation in the short term, we can’t guarantee that issues won’t come up again.
