See exactly where your sewer line is leaking — before we dig.

Plumbing smoke tests use products intended for leak tracing, but preparation still matters. Before testing, tell us about asthma, respiratory sensitivity, pets or other health concerns so precautions can be discussed. We explain the test and the product being used, check drain traps and coordinate around smoke alarms without leaving fire protection disabled. Smoke should remain within sound plumbing and exit at expected vent locations; smoke appearing indoors needs investigation and ventilation. Avoid breathing visible smoke directly, and report any discomfort immediately so testing can stop.

A straightforward residential test may take about thirty to sixty minutes once access is ready, but that is an estimate rather than a guaranteed appointment length. The number of lines being tested, cleanout access, trap preparation and the time needed to trace escape points can extend the visit. We first review the symptoms and test area, prepare the plumbing, introduce smoke and document what we find. If several areas need separate testing or another diagnostic method is needed, we explain the next steps before proceeding.

No. Smoke testing is useful for tracing openings that allow sewer gas or test smoke to escape, including certain failed joints, cracks, unsealed cleanouts and dry traps. It does not show the inside of the pipe, reliably diagnose every blockage or measure a sag in the line. Some defects may be hidden or isolated from the test path. A camera inspection and other checks may be needed to build a fuller picture. We interpret smoke locations alongside your symptoms rather than treating one test as a complete condition report.
