HOW TO LOCATE AN ODOUR PROBLEM: A Guide to Smoke Testing
Unpleasant odours can be more than a simple nuisance. They often indicate a larger problem hidden out of sight. For example, a leak in your sewer line or an issue with the plumbing vent system. Locating the source of the odour is crucial. However, it can be challenging when the issue is underground or hidden behind walls. An effective method for pinpointing the origin of these smells is smoke testing.
In this post, we will explore what smoke testing is, how it works, why it is useful, and what you can learn from the results.
WHAT IS SMOKE TESTING?
Smoke testing is a diagnostic technique used to locate odour problems. Our odour consultants pump non-toxic, artificial smoke into a system, such as a sewer line or vent. The smoke follows the same path as air (or odour) would. We carefully monitor where the smoke emerges, both inside and outside affected buildings. This highlights leaks and breaches, which typically reveal the cause of odour problems. They may also indicate structural issues. These could include cracks in pipes, faulty seals, or unauthorised openings.
HOW CAN YOU USE IT TO LOCATE ODOUR PROBLEMS?
STEP ONE: Seal off vents and openings
First, the smoke test starts by temporarily sealing off any openings or vent pipes. By doing this, we ensure that the smoke flows through the system. This allows it to pressurise and escape only through leaks or intended openings.
STEP TWO: Introduce the smoke
After sealing the system, we introduce smoke using a high-powered smoke generator. This machine pumps non-toxic, visible smoke into the system. Usually, we start at an accessible point such as a manhole opening.
STEP THREE: Observation
As the smoke travels through the system, our odour experts walk through the area, both inside and outside any affected building. They look for signs of smoke emerging from unexpected places. If there is a leak in the pipes, walls, or vents, the smoke will make its way through and become visible.
STEP FOUR: Identify the source
The emerging smoke reveals the location of the breach or issue causing the odour. Whether it’s a crack in the sewer pipe or a loose vent connection, this method makes the problem area clear and visible.
STEP FIVE: Video documentation
As you can see in this article, our team records the progress of the smoke. We take videos of the point where we introduce the smoke and the areas where it emerges. This can be useful for documentation, evidence, and sharing with contractors for further repairs.
WHY CHOOSE THIS METHOD?
There are several reasons why smoke testing is a great way to locate odour problems:
Non-Invasive
Other methods may involve digging up pipes or tearing down walls. Smoke testing, however, is a non-destructive way to identify leaks.
Cost Effective
Smoke testing can save time and money by quickly pinpointing the problem area. This can be significant compared to more invasive diagnostic techniques.
Fast & Efficient
Smoke testing can quickly cover large areas. In a matter of hours, we can test a sewer system, plumbing vent system, or even an entire building.
Accurate Results
The visual nature of the test leaves little room for guesswork. If smoke escapes through a crack, you know exactly where to focus your repair effort.
WHAT CAN YOU LEARN FROM SMOKE TESTING?
The results of a smoke test provide valuable insights into the state of your system.
Identify Odour Sources
The primary benefit is locating where offensive odours are escaping. For example, a cracked pipe, a dry drain trap, or improper venting.
Uncover Structural Problems
If the smoke emerges from the ground or behind a wall, it can indicate a structural issue. Some possibilities could include a damaged sewer line or cracked foundation. You may also have gaps in your building’s air-tightness.
Verify Integrity of Repairs
After a repair, we can conduct a second smoke test to ensure the problem has been resolved. This will confirm that the leak is sealed and no further odours will escape.
Check for Unauthorised Connections
In some cases, smoke testing can reveal unauthorised or unknown connections in your system. These might not cause an odour directly, but they could present future issues.
