Sewer lines are out of sight, so problems often go unnoticed until a backup occurs. Understanding the common causes can help you prevent them.
The Usual Causes
- Tree roots entering through cracks and loose joints.
- Grease, oil, and fat that harden and build up on pipe walls.
- Age and corrosion, especially in older clay and cast iron lines.
- Shifting or settling soil that offsets or bellies the pipe.
- Flushing items that do not break down, such as wipes and paper towels.
How to Reduce the Risk
- Never pour cooking grease down the drain.
- Only flush toilet paper and human waste.
- Be mindful of where trees are planted near sewer lines.
- Have your line inspected with a camera if you have recurring clogs.
