In this article, we will discuss the signs of a sewer backup so you can assess the situation and take the appropriate measures. But before we get into the signs, let’s take a look at what causes a sewer backup in the first place.

What are the Causes of Sewer Backups?

There are several things that can cause a sewer backup. The majority of these are human-related mistakes that can easily be avoided. Some of the most common causes of sewer backups are:

Clogged or broken pipes

Pipes can become clogged over time due to build-up from soap, hair, grease, and other debris. Clogged pipes can also be caused by tree roots growing into the sewer line. Additionally, pipes can break from freezing weather or simply age and wear. If it is inspected regularly, this can cause a sewer backup.

Overflowing sump pumps and septic tanks

How Do You Know if Your Sewer is Backed up? Here are the 8 Critical Symptoms

1. Slow Drains

One of the most common signs of a sewer backup is slow drains. If you notice that your sinks, showers, or tubs are draining slowly, it could be a sign that something is blocking the line and causing the backup.

You can also try pouring a pot of boiling water down the drain to clear it out. If that doesn’t work, then you likely have a sewer backup on your hands. If this is the case, you should call a plumber immediately to take care of the problem.

Professional plumbers will inspect your sewer or drains using a camera to see the problem and unblock it with high-pressure jetting equipment or by utilizing a drain cleaner.

2. Gurgling Noise

If you hear a gurgling noise coming from your toilet, kitchen, or shower drains, it is a sign that there is air in the line and that the sewer is backing up. Sometimes you can see bubbles in the water when this happens.

3. Toilet is Backing Up and Overflowing

It is common for the toilet to become backed up, but it could be a sign of a larger issue if it happens frequently. If the water in the toilet is backing up and overflowing, it is a sign that you have a blockage somewhere in the sewer line.

4. Foul Odor
