Smoke Test

Standard smoke testing per industry standards.


This is a standard smoke test, wherein we send non-lethal smoke through a pressurized line from the cleanout, and walk the space to see if any smoke is found, indicating a possible leak.

Definition:  Smoke testing involves forcing smoke through a sewer line. The smoke, once under pressure, fills the main line(s) and any connections; if there is a leak in the line, smoke will come up through it and be visibly detectable.


Scope of Work

  1.   Close all open vents and connections.
  2.   Introduce smoke to the system using blower machine at the cleanout.
  3.   Walk space searching for any location where smoke may appear.
  4.   If smoke is found, investigate what the issue may be and make repairs if minor.  Major repairs will be quoted prior to work being performed.
  5.   Document and report any and all issues found.
  6.   Clean up area, remove trash, tools, and equipment from jobsite.
  7.   All work performed during normal business hours.
