How You Can Tell that Your Sewer Line is Blocked

Although it is often difficult to know when your sewer line is blocked or not, there are few signs that help you to determine. As a responsible homeowner, you should be aware of the basic signs to identify if your sewer line is healthy or not. Here are some of the signs to look for.

1. Multiple backed-up drain

The sewer system in your home, has many different parts spread throughout your home. This means that whenever there is a plumbing issue in one part of the line, it will definitely affect other parts of the system. It’s a domino effect, an issue in one part will cause issues in other parts as well.


One example would be if your tank is blocked, the drains for your tank will have issues as well. As the water flow in the blocked drain, it would sometimes create a gurgling noise it travels through pockets of air. It is common to hear this sound from the shower, sinks or even bathtub. So if you keep experiencing multiple backed-up drains then you may want to contact your local plumber for inspections

2. Check the Water in the Sewer Clean-out

Another easy way to determine that your sewer line is blocked is by inspecting your home’s sewer clean-out. Most newer homes would have clean-outs with removable lids. Open the lid and look for signs of standing or flowing water. If the water in the clean-out is not moving at all, then you probably have blocked sewer line.


3. Overflowing Water

Another sign of blocked sewer system is when you notice overflowing water in other plumbing fixtures. If you see sewage water or wastewater coming through your shower drains, then your sewer line is definitely blocked. Here are some things you need to check if you suspect an issue in the sewer system:

  • If you notice any water coming up the drain when you turn your dishwasher machine.
  • If you notice the toilet water rises up when you turn on the sink water.
  • When you flush the toilet, water comes up through the shower drain.

If you notice any of these signs, make sure you call your trusted plumber that handle the issues.


4. Strong Sewage Odor

This could be the easiest way to tell if you have an issue in the sewer system. If you notice a sewage smell from any plumbing fixtures, then it is likely that there is an issue in your home’s sewer system.


If you notice any of these signs, then maybe it’s time to call Mr. Splash Local Inner West to help you fix your sewer system.
