3 inch PVC is often used to vent radon outdoors, and can be used in a variety of configurations. Suction points draw radon out through crawlspaces, garages, drop ceilings, etc., using a coring bit to drill through basement slabs and create suction. Fan ON - OFF switch provided in the basement on every installation. Suction can be observed through a u-tube manometer, and come with a state mitigation tag and radon information packet.
