A sewer smell inside your home is more than unpleasant. It can be a sign of a real problem with your drain or sewer system, and in some cases, sewer gas can pose a health risk. If you’ve noticed persistent odors and can’t find the source, TMS uses professional smoke testing to identify exactly where sewer gases are escaping into your home. It’s a fast, non-invasive diagnostic method that takes the guesswork out of finding hidden leaks and gaps in your plumbing system.
What Is Sewer Smoke Testing?
Smoke testing is a diagnostic technique used to find cracks, leaks, faulty seals, and improper connections in drain and sewer lines. Here’s how it works:
Non-Toxic Smoke Is Introduced: A safe, non-staining, non-toxic smoke is pumped into your plumbing system through a cleanout or access point.
Pressure Fills the Pipes: The smoke fills the interior of the drain and sewer lines under light pressure, reaching every connected pipe and joint.
Leaks Reveal Themselves: Anywhere the system has a crack, gap, failed seal, or improper vent, smoke will emerge. This makes the problem location immediately visible.
We Document and Diagnose: Our plumbers identify every location where smoke appears, document the findings, and recommend the appropriate repair for each issue.
