What’s That Smell? Common Causes of Foul Odours in Commercial Buildings and How to Fix Them

If you detect a strange foul smell in your building and can’t figure out where it’s coming from, it may indicate problems with your plumbing or septic system. In this blog, we’ll go over the challenges of commercial drainage and some causes of bad smells in commercial properties.

Commercial Plumbing and Its Unique Drain Challenges

Commercial plumbing is a much more complex beast than residential plumbing. Many people don’t give much thought to drainage solutions - they just notice when they don’t work properly.

 

For example, commercial buildings often have large roofing systems, which collect a lot of water when it rains. A clogged drain or gutter is a significant problem.


Common Causes of Bad Odours in Commercial Properties

Determining where that sewer smell is coming from can drive you mad. However, if you follow this guide on the common causes, you might be able to narrow it down. Calling a professional plumbing service can also help you find the source of the smell.


Improper Venting

If your vents were installed improperly during construction, sewer gases can escape from the sewer lines into your building. If left unresolved, those gases and the associated odour can pose a health risk to any occupants and reduce the appeal of your building. High-quality plumbing services can help you resolve this issue.


Clogged Vents

Similar to the last issue, debris falling into the vents can cause clogs, which can prevent the sewer gases from escaping properly and cause them to back up into your building. If you notice any bad odours, you can call professional drain cleaning services to clear your vents and restore the clean air in your facility.


Sewer Line Backups

If there are any blockages in your sewer or septic lines, it can lead to a sewage backup. Backups of sewage can cause serious damage to the flooring and materials in your commercial building, and a foul odour is an early sign of that issue. Professional drain services and pipe inspection can provide the necessary solutions.

 

Sewer line backups can indicate septic tank problems if you are on a septic system.


Dry P-traps

P-traps are the bend in the pipe that collects water and debris, preventing clogs further down the pipe and blocking sewer gases from entering the interior of your building. If left unused for a long time, p-traps can dry out, allowing sewer gases to move freely into the air you breathe. You can easily fix this problem by running water into the drain for a minute and letting the trap back up.


Your Septic Tank May Need Pumping

If you are on a septic tank system, a bad odour may indicate that you need septic tank pumping services. You may also notice sewage backing up into your building. You should pump septic tanks every 3-5 years, depending on how big your tank is and how many occupants the building has.
