I totally get the frustration. I tried using those little metal key tags once, thinking they'd last forever, but by spring they were all crusty and unreadable. Ended up scribbling a map on the back of a pizza box instead. Not the most professional, but at least cardboard doesn't rust...
I tried those plastic plant tags once, thinking they'd be more weatherproof than metal. Turns out, the sun just faded them until everything was labeled “???” by summer. Ended up using a chunk of old tile and a Sharpie. Not exactly high-tech, but at least it survived the rain.
I hear you on the labels—tried those “weatherproof” stickers on some shutoff valves once, thinking they’d last. By the time I needed them, all I had was a bunch of blank, peeling messes. Ended up just scratching notes right onto the copper with a nail. Not pretty, but at least I could tell hot from cold. Sometimes the low-tech fixes just work better, even if they look rough.

I get the appeal of just scratching notes in—definitely hard to argue with something that won’t peel off. Still, I’ve had decent luck with those aluminum tag labels you can tie on with wire. They’re not pretty either, but they don’t fade or fall apart like stickers. Plus, if you ever need to update info, you can just etch a new note in. Might be worth a shot if you want something a bit more legible than nail scratches.

Yeah, those aluminum tags are a step up from stickers, for sure. I’ve used them on a few jobs where the inspector wanted everything labeled and legible. They hold up way better than anything adhesive, especially in damp basements or crawlspaces. Only thing is, if you’re in a tight spot or working overhead, trying to etch something readable on a swinging tag can be a pain. I’ve definitely ended up with a few that look like chicken scratch.
Honestly, I’ve just gotten used to keeping a notebook with rough sketches and notes for anything complicated. Not the most high-tech solution, but at least I know where everything ties in when I get called back years later. The problem is, nobody else ever looks at your notebook, so if someone else comes in after you, they’re back to square one unless you left something on the pipe itself.
I’ve seen some guys use paint pens or even engravers, but those don’t always last either—paint flakes, and engravers are slow if you’ve got a lot to mark. The best system I’ve seen was a guy who used color-coded heat shrink tubing with numbers written on them. Looked a bit over the top at first, but you could actually tell what was what even after a few years.
At the end of the day, nothing’s perfect. Between condensation, heat, and people banging into stuff, most labels don’t stand a chance. I guess that’s why half the time we’re all just tracing lines and hoping for the best...
