Why Does My Sewer Line Keep Backing Up?

A plumber uses a plunger to unclog a toilet.

All homeowners can agree that a sewer line backup is the stuff of nightmares. Unfortunately, not only do sewer backups happen, but certain circumstances can make them a recurring issue. Here are the top three reasons this pungent problem may persist and the scoop on how to handle them.

1. Constant Clogs

Basic clogs are by far the most common cause of sewer lines backing up. They are typically the result of not being careful with what goes down your drains. Failing to clean up hair from the shower drain, pouring oil down the sink, and using “flushable” wipes are the most common paths to backups. Getting everyone in the household on board with what can and cannot go down the drains or in the toilet can go a long way toward preventing consecutive backups due to clogging.

2. Tree Root Infiltration

The trees in or near your yard may be beautiful, but they may also be growing close enough to your sewer line to cause misalignments, leaks, and other damage. What’s worse, the roots receiving nutrients from the damaged line will begin growing toward the line and compounding damage as they infiltrate cracks.

3. General Damage

There are many reasons, including general wear and tear, that can cause damage to a sewer line. If your line cracks, develops holes, or sustains other damage, dirt and rocks can enter the breakage and create a new block that prevents wastewater from properly draining. Backups can also be caused by sagging or collapse, which typically occurs due to age or heavy construction in the nearby vicinity.

Bring In the Backup

Trying to address a sewer line backup on your own is both an undesirable and potentially dangerous idea. Call in the professionals if you are experiencing repeated backups. Certified experts can bring in a sewer line camera to find out what is causing the repeated block, gauge the line's health, and perform the repairs and replacements necessary.
