Drain Line Smoke TestingSewer odors. Pest entry. Hidden cracks.
Drain line smoke testing is the most reliable way to find cracks and gaps in your plumbing drain system — the same openings that let sewer gas, odors, and pests into your home. We introduce non-toxic smoke under low pressure and map every exit point. Detection only (no repairs) — clear findings and photos for your plumber.

What Drain Line Smoke Testing Finds
Sewer Gas / Odors
H2S (hydrogen sulfide) from cracked drain lines can enter your home causing health concerns and unpleasant smells. Smoke testing reveals exactly where the gas is escaping.
Pest Entry Points
Roaches, drain flies, and rodents enter homes through cracks in drain lines. Smoke testing pinpoints every breach in the system that allows pests inside.
Vent Pipe Failures
Failed plumbing vent connections allow sewer air to flow backward into living areas instead of exhausting through the roof. Smoke testing quickly identifies vent failures.
Hidden Drain Cracks
Underground or in-slab drain line cracks allow sewer gases to seep into the soil and migrate into the home through foundation cracks or floor drains.
How Drain Line Smoke Testing Works
Seal Drain Openings
We temporarily plug open drains in the home to contain the smoke within the drain line system under controlled pressure.
Introduce Smoke
Non-toxic smoke is introduced into the drain line system through a cleanout. The smoke fills the entire system under low positive pressure.
Map Exit Points
Smoke exits through every crack, gap, or failed connection in the system — making each problem location immediately visible. We photograph every exit point.
Clear Report
You receive a written report documenting each exit point, its location, and photos. Your plumber uses this to repair only what needs it.
Drain Line Smoke Testing FAQs
What is drain line smoke testing?
Drain line smoke testing is a non-invasive diagnostic process where we introduce non-toxic, non-staining smoke into your drain line system under low pressure. Wherever the smoke exits — through cracks, bad connections, or open joints — we can see exactly where the problem is.
Is the smoke toxic or harmful?
No. We use non-toxic, non-staining smoke specifically designed for plumbing inspection. It is safe for indoor use and dissipates quickly with ventilation.
Why would I need drain line smoke testing?
The most common reasons are: unexplained sewer odors, pest infestations through drains (cockroaches, drain flies, rodents), or suspicion of a cracked drain line after foundation work or root intrusion.
Do you repair drain lines after the smoke test?
No — we are detection only. We locate the problem and document it with photos and a written report. Your plumber handles the repair.
How does smoke testing find pest entry points?
Smoke escaping through the same cracks and gaps that pests use to enter your home makes those entry points immediately visible. This is one of the most reliable ways to confirm pest access through the plumbing system.
How long does drain line smoke testing take?
A typical inspection takes 45 minutes to 1.5 hours depending on the size of the drain system and number of identified issues.
Will the smoke affect my smoke alarms?
We take precautions during testing. If your alarms are particularly sensitive, we'll advise you on temporarily isolating them. The smoke is low-density and dissipates quickly.
Can smoke testing find a sewer smell that plumbers couldn't locate?
Yes — this is one of the most common scenarios we encounter. Plumbers check for active water leaks; drain line integrity is a different inspection. Smoke testing finds the exact breach that allows sewer gas in, which other methods often miss.
Do you offer smoke testing in Volusia and Seminole County?
Yes — we serve all of Volusia, Seminole, and Orange County including Deltona, DeLand, Sanford, Lake Mary, Longwood, Altamonte Springs, Orlando, Daytona Beach, Port Orange, and surrounding communities.
What do I get after the smoke test?
You receive a detailed invoice documenting every exit point found during the test, the severity of each, and photos. Your plumber uses this to make targeted repairs to the drain system.
