2. Smoke testing (mechanical) - Wikipedia

   en.wikipedia.org/wiki/Smoke_testing_(mechanical)

   In plumbing a smoke test forces non-toxic, artificially created smoke through waste and drain pipes under a slight pressure to find leaks. [4] Plumes of smoke form where there are defects. This test can be performed when the plumbing is brand new, but more often it is used to find sewer gas leaks that may plague a building or an area. [4]

3. Leak detection - Wikipedia

   en.wikipedia.org/wiki/Leak_detection

   A leak appearing within an analytic region (a rule added to the camera) is immediately analyzed for its attributes, including thermal temperature, size, and behaviour (e.g. spraying, pooling, spilling). When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station.

4. Tracer-gas leak testing - Wikipedia
