Ok, but WHY does it smell like sewage in my house?

What To Do If Your Sewer Backs Up

If you have a backed up drain or backed up sewer line on your hands, it’s no fun – but there are a few things you can do to start dealing with this inconvenient occurrence. First, stop using the water to prevent the back up from worsening.

Next, try a plunger and try to clear any blockages from sinks or toilets or floor drains. Do Not Use Chemical Cleaners. They are corrosive to plumbing and bad for the environment.

If you haven’t remedied the situation, it’s time to call the professionals. Experts of drains and sewers will assess the situation, and their experience and knowledge typically will lead to the issue being resolved quickly. This is the best way to ensure you don’t experience any potential health risks and prevent the back up from getting worse and costing you more in damages.

Here is a hot tip; if you've had a sewer backup and cleared the system so that it is flowing again, but a sewer smell persists, there could be waste from the initial backup lingering in the floor drain trap. Try flushing the basement floor drains with buckets of water, again only if the system is functional and flowing

Preventing Future Back Ups with Regular Maintenance

Backed up sewers and sewer smells are a dreaded occurrence, but the good news is that you can take some simple preventative measures to avoid this unfavourable situation. Regular maintenance is key. Drain cleaning or cleaning out any gunk, debris, or hair from your drains and sinks regularly will make a huge difference.

Inspecting your sewer line with a sewer camera scoping is the best way to know if it is failing or if there are any drain problems that could lead to a backup. By proactively checking the state of your sewer line you can make any necessary plumbing repairs ahead of an emergency.


These are a few things you can do to avoid having to call a plumber to fix issues that get out of hand – which also saves you money and headaches!

Methods of Fixing a Backed Up Sewer

There are a few ways to tackle this stinky situation. One option is to whip out a trusty drain snake - a flexible, long tool that can slither through the pipes and break up clogs.


But when things get nasty, you might need to take it up a notch with a hydro jetting. This option is a high-pressure water jet, blasting away any blockages with powerful streams of water.
