Smoke Testing

About Smoke Testing

BlueWater Solutions Group conducts sanitary sewer smoke testing in order to detect defective and improper connections by blowing non-toxic and odorless smoke into the sewer. If no defects are present, smoke will only be visible from manhole to manhole and on rooftop vents for each building that is connected to the sanitary sewer. When defects are present, smoke will come through the defect. Smoke should not enter buildings unless there are leaks or defects in the plumbing. Should smoke enter your building, open a door or window, turn on exhaust fans, and notify the field crew leader in your area or contact the project manager for additional assistance. People with respiratory concerns are advised to leave the premises during the smoke testing.

To help prevent smoke from entering your building, pour 24 ounces of water into your basement floor drains as well as all drains in sinks, bathtubs, and showers. Adding vegetable oil will also help to slow down the evaporation of water in the P-traps.

Smoke Testing FAQs

No. The substance that is used is non-toxic and does not pose a fire hazard. However, it is not recommended for people with respiratory problems to remain in the area while testing is in progress.

Fill your drains that are seldom used with approximately 24 ounces of water. Adding some vegetable oil can help in slowing down the evaporation of water in the P-Traps.
Residents do not need to be home and at no time will field crews need to enter residences or buildings. Smoke testing crews will be outside documenting the testing, taking photos, and measuring distances.
Notify the field crew leader of where in your building there is smoke coming through so they can properly document the defect. You should have received a pamphlet with the appropriate contact information in the days or weeks prior to testing. If the smoke is heavy in quantity, it is advised to open some windows and turn on vents to help the smoke dissipate. You may also want to temporarily leave the building if it is consuming the whole premises. The smoke should disappear quickly if these actions are taken.
