Product Description

If you live in a cold weather environment your sanitary waste system’s roof vent line probably freezes in the winter. As warm, moisture-laden air rises through the vent, the cold outside temperature causes it to condense and freeze on the vent line eventually plugging it. Without a place for it to escape, sewer gas backs up into your home and can cause unpleasant odors, nausea, headaches and even illness.

The Frost Free Sewer Vent employs a one-of-a-kind air chamber to insulate the warm air from cold, preventing freeze and keeping the sewer gas from backing up. It is simple to install in minutes and will save you dangerous trips to an icy roof in the winter.
