Sewer Smoke Testing in Woodland Hills, CA
When you smell sewer gas in a home or commercial building and the source is not obvious, you need a way to find it.

Bryco Plumbing performs sewer smoke testing across Woodland Hills, the SF Valley, LA County, and Ventura County for both residential and commercial properties. License #708581. The right diagnostic for problems that other methods miss.

Our Smoke Testing Process
Step 1: Pre-Test Inspection
We walk the property, locate cleanouts and vents, identify possible problem areas, and document baseline conditions. We coordinate with you on access to areas where smoke might be visible during testing (attic, crawl space, exterior walls, yard).
Step 2: System Preparation
Drain traps are checked to ensure they are full of water (so smoke cannot escape into living spaces through fixtures with dry traps). We coordinate with anyone in the building so they know what to expect, and we notify the local fire department for larger commercial tests so a passerby calling 911 about visible smoke does not trigger an unnecessary response.
Step 3: Smoke Introduction
A specialized blower with a smoke generator is connected to a cleanout. Non-toxic, non-staining smoke fills the sewer system over a controlled period. We monitor the entire property during the test.
Step 4: Documentation
Every place smoke escapes gets documented with photos, video, and a written notation of the location and what it indicates. You receive a full diagnostic report after the test.
Step 5: Repair Recommendations
Based on what the test reveals, we provide repair recommendations with priority levels (immediate, short-term, monitor). Some smoke test findings are minor and informational. Others are actionable problems that need addressing right away.

When Sewer Smoke Testing Is the Right Call
- Persistent sewer gas smell in a building with no obvious source. The smoke comes out of the leak point, even if the leak is small enough that you cannot otherwise see it.
- Suspected venting issues causing gurgling drains, slow drainage, or repeated trap siphoning. Smoke shows which vents are blocked or improperly routed.
- Investigation of cross-connections (where storm drains connect to sanitary sewer or vice versa) which are a common problem in older neighborhoods and a code violation in California
- Pre-purchase commercial property inspection on buildings with complex plumbing systems or where the buyer suspects undisclosed plumbing issues
- Diagnosing the source of mysterious moisture in walls, ceilings, or foundations where camera inspection has not found a definitive cause
- Verification after major sewer work to confirm the system is properly sealed and all venting works correctly
What Smoke Testing Can Reveal
Smoke testing shows you exactly where the problem is, in real time, with visible evidence.
- Cracked or broken sewer lines underground. Smoke escaping through soil to the surface marks the location precisely.
- Failed wax rings under toilets. Smoke comes up around the base of the toilet, revealing a seal failure.
- Broken or disconnected drain fittings inside walls. Smoke seeping from baseboards or wall outlets shows hidden damage.
- Improperly installed or broken vents through the roof or in walls
- Unsealed cleanouts and access points. Smoke escaping at these points indicates seals that should be replaced.
- Sump pump or floor drain issues (smoke coming from a floor drain often indicates a dry P-trap or a failed trap primer)
- Illegal connections between sewer and storm systems, or unauthorized branch connections
What Sewer Smoke Testing Is
This is the diagnostic plumbers use when more conventional methods (camera inspection, dye testing, pressure testing) have not found the issue. It is particularly effective for finding small cracks too small for a camera to clearly identify, leaks between fittings, improperly sealed joints, and illegal or unintended connections.
Why a Smoke Test Is Worth It
- Smoke testing shows you exactly where the problem is, in real time, with visible evidence.
- For a homeowner dealing with mystery odors or a commercial property manager who needs to find a specific issue without unnecessary excavation, the cost-benefit is overwhelming.

Frequently Asked Questions About Sewer Smoke Testing
Yes. The smoke we use is non-toxic, non-staining, and approved for use in occupied buildings. It is the same product used by municipal utilities and professional commercial plumbing inspectors. People with severe respiratory conditions may want to step outside briefly during active testing, but most residents and tenants experience no issues at all.
A residential smoke test typically takes 90 minutes to 3 hours from setup to final documentation. Commercial buildings with larger systems can take half a day to a full day. The actual smoke phase of the test is shorter (usually 30 to 60 minutes), with the rest of the time spent on preparation, walkthrough, and documentation.
No. The smoke is non-staining, non-toxic, and dissipates within minutes of being introduced. It does not damage walls, flooring, furniture, or fabrics. The only place you should see smoke is where there is a leak or escape point in the sewer system, which is the entire point of the test.
Camera inspection shows you the inside of the pipe. Smoke testing shows you where the pipe is leaking. They answer different questions. Smoke testing is the better diagnostic when the suspected issue is small cracks or failed seals that a camera cannot clearly see, when you need to find venting issues, or when you are investigating sewer gas smells of unknown origin. Often we use both together for full diagnostic coverage.
