Drain Smoke Testing

Drain Smoke Testing Experts

Smoke testing refers to the system that is intended to determine the presence of cracks, leaks, or breaks in a closed system of pipes with the help of smoke. Drain Smoke Testing involves non-toxic, artificially created smoke; it forces this smoke to penetrate through drain pipes under a slight pressure. Any sign of smoke escaping can be considered a possible sight for future gas or water leakage.

Drain Smoke Testing can be done in new plumbing sites but is more often used to find sewer gas leaks that may plague an area. Smoke is created using smoke bombs or liquid smoke. Smoke bombs are lit and placed on a grate on top of a fan, while liquid smoke is injected into the fan by a heating chamber. The fans create a pressure that propels the smoke into the drain.

Why choose Drain Smoke Testing?

  • This method is helpful in detecting points of groundwater or surface water intrusion into the sewer.
  • The smoke is non-toxic, non-staining, and odourless gas that is harmless to living things, food, and material goods. It creates no fire hazard.
  • The process is very efficient and cost-effective. It is a fast procedure compared to other methods.
  • Drain Smoke Testing helps in discovering lost manholes, broken or open clean outs, and abandoned service lines.
  • This process is used to find leaks, and see if there are defect plumes of smoke coming out.
  • When using Drain Smoke Testing, it is helpful to partially block off the section of the sewer to be tested.
