We typically see piping extend up the side of the home as well as route outward around the soffit and also seamless gutter, venting above the roofing system side. Periodically we see a system that does not expand right up the wall, yet as long as it does not vent near an operable window, that is acceptable. You don't want radon being vented from the lower degree, after that just blowing back right into the home via an open home window. See to it this piping is in great condition as well as the departure factor is not blocked whatsoever.
