Sewer smells in homes and businesses are unpleasant. The most common source of sewer gas odors whether residential or commercial is a “dry tap”. A dry tap can be a sink, floor drain, or toilet that is not used for some time. The water trap in the drain line dries out and the sewer gas then backs up into the room. Broken drain lines are another common source of sewer gas that allows sewer gas into a crawl space, basement, or mechanical area. It then seeps into offices or houses. Plugged or backed-up drains are also sources of odors backing up into the air. Express Plumbing Heating & Air can locate any sewer smell by performing a smoke test to detect leaks.

Our smoke machine blows non-toxic smoke into the sewer system. The smoke sills the pipe system and smoke escape from problem areas, such as cracked or broken pipes, revealing the source of the leak. Smoke escaping from any point can be a site for sewer gas to escape. We can then pinpoint any areas sewer gases are escaping from. Then make a proper repair to fix the concern.

Smoke testing can detect cracked sewer pipes, abandoned floor drains, or a poor seal. The source of mysterious odors can cause health issues. Smoke testing can help avoid this issue. It is fast, efficient, and cost-effective. Because of this, it has become a world-standard detection practice. If you have an unpleasant smell in your house or business, call Express Plumbing Heating & Air today to schedule your smoke testing appointment.
