Tips to prevent smoke from entering your home (complete prior to test)

  • Run water faucets for a few seconds in unused sinks, tubs, and drains to fill fixture traps.
  • Pour water into each basement floor drain (at least 1 gallon).
  • If you have defective plumbing (i.e. no trap) you should consult with a licensed plumber.

If you notice smoke in your home

  • Do not become alarmed.
  • Open doors and windows to ventilate the premise to clear smoke.
  • Please notify our work crews by calling the Smoke Testing Crew Chief at 651-238-0572.
  • Simulated smoke will not stain walls or furniture; nor will it leave a residue.
  • Consult a licensed plumber in the near future to identify the smoke access area, as the potential exists for sewer gases to enter you home in the same manner.
