What is Smoke Testing?
Smoke testing is a way to check the sewer system for points where rainwater may be entering incorrectly. During the test, safe, non-toxic smoke is blown into the sewers, and technicians observe where it escapes above ground — for example, from catch basins, vents, or roof drains.
Is this smoke harmful?
No. If the smoke enters your home, it may make you cough, but it is not harmful to your health and will not harm pets, clothing, draperies or furniture.
What should I do to prepare for smoke testing?
Ensure all plumbing traps have water in them as soon as you receive this notice. To do so, pour a few cups of water down drains, sinks, washing facilities and floor drains. You may also wish to leave a few upstairs windows open a small amount, if you feel safe doing so during the testing period.
Do I need to stay home for the duration of the test?
No, you do not need to be home when testing is being performed.
Why does smoke enter homes sometimes?
Smoke may enter if plumbing traps are dry or improperly sealed. This indicates a potential path for sewer gas but is not dangerous.
What should I do if smoke enters my house?
If smoke gets into the house, how long does it take to dissipate?
The smoke will dissipate in a few minutes. Open windows for ventilation.
What happens after testing?
The City will contact residents only if issues are found that require follow-up. Most residents will not see smoke at all.
