This comprehensive guide will walk you through the steps to tackle that stubborn clog, restore proper drainage, and save on costly plumbing services.


1. Signs of a Main Sewer Line Clog

Before we dive into the cleaning process, let's identify the common signs of a main sewer line clog:

  • Multiple drains are slow or clogged simultaneously.
  • Gurgling sounds from drains or toilets.
  • Water backups in drains, showers, or toilets.
  • Unpleasant sewage odors in your home or yard.

2. Tools and Safety Precautions

Gather the following tools and materials, and don't forget to take safety precautions:

  • Plumber's auger or sewer snake
  • Garden hose
  • Safety gloves and eyewear
  • Rubber boots
  • Access to a cleanout or sewer trap
  • Plastic bucket
  • Old towels or rags
  • Ensure you're dressed in appropriate attire to protect yourself from potential sewage exposure, and always exercise caution throughout the process.

3. Step-by-Step Guide to Clearing the Clog

Follow these steps to clear a main sewer line clog:

Locate the main cleanout or sewer trap in your yard or basement. It's a pipe with a removable cap that provides access to the sewer line.


Insert a plumber's auger or sewer snake into the cleanout or sewer trap and feed it slowly into the sewer line.


Turn the auger's handle clockwise while applying gentle pressure. Continue until you feel resistance, which indicates you've reached the clog.


Rotate the auger in both directions to break up the clog. Then, slowly withdraw the auger from the sewer line.


Flush the sewer line with a strong stream of water from a garden hose to wash away any remaining debris.


Replace the cleanout or sewer trap cap, and check your home's drains and toilets for improved drainage.


4. Preventing Future Sewer Line Issues

To prevent future main sewer line clogs:

  • Dispose of grease and oil properly; don't pour them down drains.
  • Avoid flushing non-flushable items down the toilet.
  • Regularly maintain your sewer lines and schedule professional inspections.

5. When to Seek Professional Help

If your attempts to clear the clog are unsuccessful or if you're uncomfortable with DIY repairs, it's advisable to call a professional plumber. Some clogs may require specialized equipment or expertise to resolve.
