Totally agree—it's usually the small stuff that gets overlooked. Last year, I thought I had everything covered, then realized the outdoor faucet wasn't drained properly...lesson learned. Sometimes it's not about spending more, just knowing exactly what to check.
Yeah, it's funny how those little things sneak up on you. Reminds me of when I was helping my uncle winterize his cabin a couple years back. We thought we'd nailed everything—pipes drained, heat turned down, cabinets open—but totally missed the washing machine hoses. Came back in spring to find a mini indoor skating rink in the laundry room...not exactly the welcome we expected.
Since then, I've been kinda obsessive about double-checking appliances and fixtures that aren't obvious. Like, who thinks about washing machine hoses or dishwasher lines? But they're just as vulnerable as outdoor faucets. It's not always about knowing more, sometimes it's just about thinking differently or questioning what seems obvious. Guess that's part of the learning curve with plumbing—there's always something new to catch you off guard.
