This raised ranch in Redding, CT, built in 1989, had a radon level of 4.0 pCi/L and a mostly finished basement with a small unfinished space. The client opted for a one-pipe system, installed in the unfinished section on the left side of the home when facing it. The pipe was positioned near the indoor fridge, and routed rightward on the exterior to run cleanly beside the existing AC pipe.
