This is a home in which the entire main floor of the house was under going a major remodel. The homeowner had a 2×6 wall built out with the intention of having our system in this space. The suction point is located in the utility room and routes into the main level behind the new framing and into the garage rafters where the radon fan is located. The piping penetrates the roof and exhausts the soil gasses one foot above the roofline.
Although technically an externally routed system, we routed the piping through a small closet horizontally to get there. This basement was 100% finished with sheetrock, tiles, finished ceilings, and carpet. We placed our suction point next to a plumbing stack to utilize the potential air channels. Levels of 0.8 pCi/L!
The only possible way to keep this system internally routed was a 2 story closet run with both closets lining up with one another and the radon fan in the attic space. We jog the pipe over in the hallway closet on the main level to route the pipe against the wall of the upstairs bedroom closet.
