Sewage backups can be a nightmare for homeowners. Not only is a clogged sewer line inconvenient, but it can also be a costly repair that can take a toll on your wallet. It is important to know the signs of a sewer line clog so that you can catch it early and prevent further damage. In this blog post, we will discuss the top signs that your sewer line may be clogged.

Multiple Drain Blockages

If you’ve noticed that more than one drain in your home is clogging, such as your shower, sink, and toilet, this could indicate a sewer line blockage. When your main line is clogged, all the other pipes will be affected.

Slow Drainage

Does your sink take longer than usual to drain? Or does your toilet bowl take forever to clear out after flushing? This could be a sign that your sewer line is backed up, causing a slow drainage system throughout your home.

Foul Odors

If you notice an unpleasant sewage smell coming from your drains or outside of your home, this could indicate a clogged sewer line. The wastewater and sewage in your pipes often emit a strong odor, which is more noticeable when the line is obstructed.

Strange Sounds

Gurgling sounds coming from your pipes may indicate a blockage in your sewer line. When your pipes are clogged, the air that’s supposed to flow through the system gets trapped, causing a gurgling sound whenever water is drained.

Sewage Backup

The most obvious sign of a clogged sewer line is sewage backup. If the toilet or shower starts overflowing and the water doesn’t recede, you may have a serious problem with your sewer line that requires immediate attention.
