Radon Mitigation System - Manometer in Wahoo, NE

This exhaust line and manometer was installed by Thrasher, whose Radon business we took over in March 2020. We checked it over for their annual maintenance and everything looks good! The manometer reads a high level, which isn't better per say, but does indicate that the fan is pulling hard to move the radon gas out from under the home and out to the atmosphere.
