About four days ago, I was in the basement and heard a chirping beep—just like the sound a smoke alarm makes to alert you to a low battery; you know, the one that makes you scratch your head and say, “Am I hearing things? What was that?” Except in this case the sound was not coming from any of the smoke detectors, at least none that I could find. Eventually I became convinced that it was coming from above the ceiling sheetrock, and further convinced that some contractor had put up sheetrock over a smoke detector. Then I became convinced that it was coming from a big junction box for our ductless mini-split system. Connor was convinced it was coming from another device, but that didn’t sound right to me. It started making increasingly shrill sounds at intervals.
I finally texted Plumber Mike, asking if it could be from the ductless system, and he said, Maybe. He and his assistant came by today to check it out. They searched and searched, going through all the same suspicions I had. But it was not coming from the ductless system, or the other. Finally they found it:
It’s a battery-powered leak detector that used to be attached to one of our old water heaters. At some point it must have gotten kicked off, and someone carelessly put it up on a shelf. A high shelf, well out of sight. Where it sat until its batteries ran low, and its trilling could confound the allegedly wise.
The batteries are out now, and it is in the trash. Sanity, for the moment, is restored.
