My company recently completed a new home with a septic system designed to handle
the effluent. During the hours of heavy usage and especially on days when the air is heavy,
there is a very prominent sewage odor which settles around the exterior of the house.
The roof vent has been installed correctly,however it is the source of the odor. Would
installation of a house trap in the basement before exiting the building, eliminate or reduce
the agitated state within the septic tank from entering the vent system and alleviate
