One of the most common questions we get at Water Heater Man is whether sewer smoke testing is safe. The answer is yes—completely safe when performed by a professional plumber.
The smoke used in sewer testing is:
- Non-toxic
- Non-flammable
- Non-staining
- Safe for people, pets, and plants
The smoke may have a light odor, similar to incense, but it dissipates quickly and does not cause harm. Municipalities and licensed plumbing companies across the country use this same testing method.
If smoke enters your home during testing, it doesn’t mean anything dangerous is happening. It simply means there’s a plumbing issue—such as a dry P-trap, cracked pipe, or venting problem—that needs attention. In fact, smoke entering the home is valuable information because it helps us identify problems that would otherwise remain hidden.
At Water Heater Man, we take every precaution to ensure the process is clean, controlled, and respectful of your home while delivering accurate results.
