FogTrace: The Smarter Way to Perform
Plumbing Smoke Tests
(Why DIY Methods Fail)
Why DIY Smoke Testing Methods Don’t Work
The most effective way to perform a plumbing smoke test is by using a system that delivers controlled airflow (CFM) and consistent pressure. Without proper pressure, smoke testing becomes unreliable and can miss hidden leaks.
FogTrace was designed specifically to solve this problem—giving plumbers a repeatable, accurate, and cost-efficient smoke testing solution.
Why DIY Smoke Testing Methods Don’t Work
Many plumbers still rely on:
- Smoke candles + shop vac
- Leaf blowers pushing smoke into pipes
While these setups seem quick and affordable, they create unpredictable results.
The Real Issues with DIY Methods:
- Too much airflow → Smoke blows past leaks and trap seals
- Too little pressure → System never fully pressurizes
- No consistency → Every test produces different results
Bottom line: You’re not testing the system—you’re guessing.
Smoke Testing Isn’t About Smoke—It’s About Pressure
A common misconception is that smoke finds leaks.
It doesn’t. Pressure does.
Simple Explanation:
- Open pipe (no pressure) → Smoke exits easiest path
- Pressurized system → Smoke is forced through cracks, leaks, and weak points
This is why controlled airflow (CFM) is critical.
Without pressure:
- Small leaks stay hidden
- Odor issues go undetected
- Repairs may fail or be incomplete
The Hidden Cost of Smoke Candles
Many plumbers stick with DIY methods to save money—but over time, it costs more.
Smoke Candle Downsides:
- Single-use only
- Inconsistent output
- Ongoing replacement costs
FogTrace Fog Fluid Benefits:
- Lower cost per test
- Consistent output
- Scalable for large jobs
- Cleaner and easier to use
Over time, FogTrace delivers significant cost savings
Why Consistency Matters in Plumbing Diagnostics
When diagnosing sewer systems, you need:
- Accurate results
- Repeatable testing
- Clear visual proof
This is especially important when:
- Explaining issues to customers
- Working with contractors
- Providing reports to municipalities
DIY methods can’t deliver this level of reliability.
FogTrace can.
When Should You Use FogTrace Smoke Testing?
FogTrace is ideal for:
- Sewer gas odor detection
- Hidden DWV leaks
- Broken or cracked pipes
- Failed or incomplete repairs
- Intermittent plumbing issues
Final Takeaway: Stop Guessing, Start Diagnosing
Using a leaf blower or shop vac might push smoke—but it won’t properly test a plumbing system.
Without controlled pressure:
- Leaks are missed
- Diagnoses are incomplete
- Jobs take longer to close
FogTrace Gives You:
Controlled airflow
Consistent pressure
Faster leak detection
Better job accuracy
Lower long-term costs

FAQ: Smoke Testing for Sewer Gas Odors
When should a plumber perform a smoke test?
When sewer odors are persistent, intermittent, or difficult to locate—especially after previous repairs have failed.
Can a smoke test find hidden plumbing leaks?
Yes, it’s one of the most effective ways to locate hidden leaks and venting issues.
Is smoke testing safe for homes?
Yes, modern fog testing uses non-toxic smoke that is safe when used properly.
Why not just use a camera inspection?
Cameras are useful for visual damage, but they don’t detect gas leaks. Smoke testing fills that gap.
