Yeah, those “dead” lines can be a nasty surprise—seen more than one that still had a trickle or worse. I’d add, if you’re tracing lines and can’t be sure, a thermal camera can sometimes help spot active ones, especially with steam. I’m with you on the heat-shrink over tags, though I’ve had mixed luck with adhesives in really damp basements. Sometimes a good old-fashioned brass tag on wire is the only thing that survives. Old plumbing really is a guessing game half the time...
Those “dead” lines are like ghosts—never trust 'em until you’ve checked twice. I’ve tried those stick-on tags too, but in my old stone basement, they just peel right off after a damp winter. Brass tags last, but I wish they weren’t so pricey. Sometimes I wonder if the original plumbers just liked to keep us guessing...

Honestly, I’m convinced they did. My basement’s a maze of mystery pipes—half of them don’t seem to go anywhere, and the rest are a guessing game every time I try to shut something off. I tried color-coded zip ties once (cheap and cheerful), but after a year, the colors faded and I was back to square one. If you ever find a budget-friendly tag that survives damp stone walls, let me know... until then, I’m sticking with my trusty Sharpie and crossed fingers.
I get the frustration, but I’m not sure color-coding ever really works long-term in a basement. I tried those plastic tags with a Sharpie, but the damp just made the writing run after a while. Ever thought about just mapping it out on paper? I did a rough sketch of my setup, and it’s saved me a few headaches. Not perfect, but at least I’m not crawling around in the dark trying to remember which pipe does what...
Mapping it out on paper is pretty much the only thing that’s worked for me too, especially after my attempt at color-coding with electrical tape completely failed. The tape peeled off in the humidity, and I kept forgetting which color I’d assigned to what anyway. I ended up with a mess of sticky residue and zero clarity.
What’s helped me the most is a combo of a hand-drawn diagram and printed labels. I switched to those aluminum plant tags you can write on with a ballpoint pen—they don’t bleed or fade, and they’re actually meant for outdoor use, so the basement damp doesn’t bother them. I number the tags instead of writing what the pipe is for (since my handwriting’s not great), then keep a laminated key in a drawer upstairs. If I ever need to show someone else (like a plumber), it makes it a lot easier.
One thing I’d add, especially if you’re concerned about safety or leaks, is to take a few photos of the setup once you’ve got it labeled. I stick those in a folder on my phone. That way, if there’s ever a problem and I’m not home, I can text the pics to whoever’s helping out. Plus, it’s handy for checking if anything’s changed or if a valve’s been bumped.
I’ve also gotten in the habit of running a dehumidifier nearby, just to keep things from getting too damp. Not sure if it’s made a huge difference, but at least the labels and pipes seem to stay cleaner.
Anyway, I totally get the struggle. Basements are just tough environments for anything that’s supposed to stay neat and organized. At least with a map and some durable tags, I’m not relying on my memory (which is definitely not getting better with age).
