How do you vent sewer gases in a basement bathroom?

Answer by  ServicePlumber (211)

Several manufactures build air admittance valves, which can attached to the nearest sink drain which will allow air to enter the system, but not escape. Never vent sewer gases directly into a home. Drains only require air to enter a system, so these "Studer Vents" answer the call for applications which can't have full outdoor access.

You will need to connect to the main vent stack some where in your house. This could be done by locating the kitchen or bathroom above you on the next floor.
