A blocked drain is much more severe than what it seems. People often disregard the signs of a coming or an already blocked sewer line and then panic when chaos ensues. This usually results in a bad smell around the house(usually toilets, kitchens, etc.) and will leave an uncomfortable sensation in the house.

A clogged sewer line can cause quite a number amount of consequences along the way. They can cause raw sewage to back up the drains and into your house which damages your pipes even further and if it manages to break, it can lead to several issues which ultimately, it’s going to take a lot of your expenses to fix it.


Here are 3 big signs to identify if your sewer line is clogged:

  1. Multiple drains are backed up

Check for these plumbing fixtures

  • Toilets
  • Bathtubs
  • Showers

These 3 plumbing fixtures are all linked with each other, so if your sewer line is clogged, all three fixtures will have an effect. For example; if you let your bathroom sink run, the toilet water will rise if a sewer line clog is imminent.


If you are using any of these plumbing fixtures and you hear a gurgling sound, then the main sewer line is clogged.

2. Water can’t be drained in other fixtures

For example; if you are using the washing machine and you notice the toilet start to overflow with water, then that means the water is trying to leave, but a clog is blocking the water’s exit and flows to another point of exit, in this case, the toilet water.


3. Drainage at the sewer clean out

A sewer cleanout is usually a black or white pipe with a threaded cap that provides access to the sewer line so clogs can be cleaned out easily.


To find the sewer cleanout, look around the sides of your house near the bushes.

Once you find a cleanout, screw off or pull the cap. If sewer water is flowing up and out of the pipe or is static in the pipe, this means that your main sewer line is clogged.


How to clean your clogged sewer line

Shut off the main water supply to your home. Look for the valve which is usually located at these places:

  • Basement
  • Near the water heater
  • Garage
  • Water meter box outside your home near the street

Afterward, call a professional plumber who can unblock drains. There are two approaches that most plumbing services take in order to unblock a drain:

  1. Run a drain auger through the sewer cleanout to clear the clog.
  2. If the first approach didn’t solve the problem, the plumber will use a fiber optic sewer line camera through the pipe to see what solution to bring.

Blocked drains are caused by wrong items being flushed, old pipes that can’t withstand the traffic, or if you have an old house and trees decided to grow its roots into the pipes.

It’s hard to pinpoint the main cause of a blocked pipe until a fiber optic camera is used.
