Interior radon mitigations are systems that have the main vent pipe from basement or crawl space through the interior of the house and through the attic and roof, and have the fan installed in the attic of the house. The fan is installed in the vent pipe under the roof and is plugged into an outlet next to the vent pipe. Ideally, the fan is placed above an area that is not sensitive to noise, such as attic of garage or above the bathroom or closets in the attic of the house, to prevent noise from being heard in otherwise sensitive living areas immediately below the fan location. Pipes are placed as much as possible in unfinished parts of basements, or closets, in combination with garage, or closets in areas above it, to keep the vent pipe out of the view from the occupant. When vent pipes enter and exit garages depending on the details a fire blocking ring may have to be placed around the vent pipe. Systems are installed allowing interior condensate water to run from the dicharge of the system to the cavity under ground. This is by design and naturally due to condensate from ground vapor that may condensate inside the vent pipe system. The discharge of the system must be vertical and above the roof. A roof jack is tied into the roofing material through which the vent pipe discharges the radon to above the roof.
