I recently inspected a home with a radon mitigation system installed. The exterior vent was constructed of a downspout turned upside down. The downspout was not flush with the vent at the time of the site inspection. The vent was also installed in the window well converted to an emergency egress.
Has anyone else seen the exterior vent be constructed of downspout material? I typically see them constructed of PVC.
Any insights will be greatly appreciated.
