Smoke Testing in McLean, VA
A persistent sewer smell can be frustrating when the cause is hidden behind a wall, beneath a floor, or inside your drain and vent system. Smoke testing provides a practical way to trace openings that may allow sewer gas to enter your home or business.
Plumbifi introduces visible, nonflammable testing smoke into the plumbing system under controlled pressure. If smoke escapes from an unintended location, it helps narrow down where further inspection or repair is needed.
Problems Smoke Testing May Reveal
- Loose or failed toilet seals
- Cracked drain or vent piping
- Open or abandoned plumbing connections
- Improperly connected fixtures
- Defects around cleanouts
- Dry or faulty traps
- Openings that allow sewer gas indoors
What to Expect During the Test
We first review where you notice the odor and inspect accessible plumbing. Drains and fixtures may need to be prepared before smoke is introduced. We then monitor rooms, plumbing connections, and other likely escape points.
If smoke appears indoors, it may indicate a plumbing deficiency that could also provide a pathway for sewer gases. We explain what we found, which areas may need access, and what repair options make sense.
