After spending many hours cleaning up the thoroughly soaked carpet in both a walk-in closet and an adjoining bedroom, I spent many additional hours attempting to fix the leaky drain pain. It turns out I’m not much of an HVAC repair technician, because two weeks later, the pan leaked again. This time, however, I was alerted to the impending soggy carpets (and another day of using the carpet steam cleaner) by the incessant (but, ultimately, pleasant) beeping of the Fibaro Flood Sensor I’d installed after the initial deluge. If the water leak had been from my water heater in the laundry room or kitchen sink, for example, there would likely have been much more water damage done by the time I woke up in the middle of the night and heard the beeping.
