You're right that the maintenance log tells a story, wendy_murphy16. If they almost never ran at 450 psi, what was the usual operating pressure they logged? I'm curious if the log shows them slowly dialing it back over the decades as things aged, or if they kept it steady. That would really show the crew's long term thinking.

That TIF8800A is a solid choice, I keep one in my truck too. I mean patricia_rodriguez is right, those old buildings hide leaks in threaded joints soap just can't reach. My rule now is detector first on anything pre-war, then confirm with bubbles if I need to see the exact spot. It just saves arguing with a homeowner who swears they smell something but you get a dry brush.

Wait, EIGHT hours of deep sleep? That's not even possible for a human body. Those knockoffs are just making up numbers to look good. I'd trust the Fitbit way more if it actually caught the wake ups. Stuff like this is why people think sleep tracking is junk.

Yeah, maybe it was just burnt out from all that hard work.
