This 2005-built home in Naugatuck, CT measured 4.5 pCi/L — slightly above the EPA action level. With the basement currently being framed to be finished, we installed a one-pipe radon system near the water heater to ensure proper placement before walls go up.The pipe was routed inside the home, traveling under the window well and exiting the rear left corner, avoiding the central natural gas meter. The homeowner’s contractor assisted by removing a 2x4 to ease installation access.
