The radon manometer reading showed a slight increase today, which caught my attention since I usually check it weekly for peace of mind. It's a small device in the basement that measures radon levels, and seeing it within safe limits always reassures me that the ventilation system is working properly. I try to log these readings each time, tracking any seasonal changes or anomalies that might indicate a need for maintenance.
