If smoke enters your home or building, open windows and/or doors to allow ventilation and note the location of the smoke emission. Smoke should clear in a few minutes. Exit the building and contact a member of the smoke testing crew working in your area. The crew member will be pleased to assist you with locating where the smoke may be entering the structure.
Please keep in mind, smoke should not enter your home or building. If smoke enters the structure, then it is an indicator that you have defective plumbing or dry drain traps. While the crew member is pleased to assist you with investigating where the smoke may be entering the structure, you are advised to consult with a licensed plumber to make repairs to your private property plumbing.
If you have seldom used drains, it is recommended that you pour water in the drains to fill the traps, which will help prevent sewer gases or smoke from entering the building. You should do this on a monthly basis to keep the traps from becoming dry.
