Great question! We do not recommend the maxi-vent system for radon. You would want to use our duke aeration system. Exhaust gasses from the aerator tank must be carried to the exterior of the building using 3" PVC pipe with cemented joints to prevent leakage of gasses before being safely vented to the exterior. Install a union fitting at the blower to facilitate lid removal when cleaning the tank. Vent piping should be as short as possible, and use "sweep" fittings when 90 degree bends are needed. Sharp 90 degree bends should be avoided to assure unrestricted flow to the exterior. The exterior end of the vent pipe should have a 90 degree elbow down turned to prevent entrance of rain and snow, and screened to exclude vermin. А 3" clothes dryer vent is an acceptable alternative for exterior venting provided connection is cemented to prevent leakage of gasses into the building. UNDER NO CIRCUMSTANCES SHOULD TANK GASES BE VENTED INTO A CRAWL SPACE, UNDER A FLOOR, OR INTO AN ATTIC. Vent should be extended above the eave of the house.
