How to Tell if Your Sewer Line is Clogged

Sewer Line Camera Inspection

A clogged sewer line is one of the most stressful plumbing problems a homeowner can face. Left untreated, it can lead to backups, water damage, and costly repairs. Thankfully, Aqua Knight Plumbing in Elmhurst, IL, is here to help you spot the warning signs early and take action before things get worse.


1. Multiple Drains Are Slow or Backing Up

If sinks, tubs, and toilets in your home are draining slowly—or worse, backing up—it’s a telltale sign of a sewer line clog. Unlike a localized clog in one drain, sewer line blockages affect the entire plumbing system.

What to Look For:

  • Water pooling in sinks or tubs.
  • Gurgling sounds when you flush the toilet or use other drains.
  • Backups occur in unexpected places, like water in the tub when you flush the toilet.

2. Foul Odors in Your Home or Yard

A sewer line clog often leads to unpleasant smells of sewage coming from your drains or seeping into your yard. This happens when waste gets stuck and can’t flow properly, causing gases to escape.

What to Look For:

  • A strong sewage odor in your bathroom, kitchen, or laundry room.
  • Foul smells outside near your sewer line or cleanout area.

3. Patches of Lush Grass in Your Yard

While green grass sounds great, unusually lush patches in your yard could indicate a sewer line problem. A crack or clog in the pipe can release waste into the surrounding soil, acting as a fertilizer.

What to Look For:

  • Overly green or wet areas of your yard, even in dry weather.
  • Puddles or soggy patches near your sewer line.

4. Frequent Toilet Backups

If your toilet keeps clogging despite regular plunging, the issue might not be the toilet itself but your sewer line. Solid waste and debris can accumulate in the main line, creating a stubborn clog.

What to Look For:

  • Water rises in your toilet bowl without flushing.
  • Needing to use a plunger more than usual.
  • Backups in the lowest drains of your home first (like a basement toilet or shower).
