Sewer odors emanating from roof vents can be offensive. We recommend purchasing and installing a unit similar to the one below on all sanitary roof vents.
The following information is from the Wager Company, Inc. This is an example of an odor control roof vent but is not the only model available. More information can be found by doing a web search or at Wager’s Website.
Wager’s 1200 Odor Control Roof Vent is designed for rooftop ventilation as a means to equalize the pressure required to keep steady flows of wastewater in toilets and sinks. Odor may become a problem when the resulting H2S gas from a septic system flows to ground levels by means of wind currents or temperature inversions.
Our 1200 model is molded from UV resistant reinforced nylon for protection from harsh environments. A slip-on sleeve allows for easy installation. Vent holes inside the unit provide a 1:1 open area of airflow. Cover vent holes are designed to restrict insects from nesting in the unit.
Each unit contains a canister with 5 lbs. of our odor scrubbing media. A groove lock top makes canister replacement quick and easy. Media and canisters are all non-toxic and landfill disposable.
