I've noticed the same thing with paint markers fading, especially in damp basements or near water heaters. Wonder if anyone's tried those industrial-grade labels electricians use—they seem tougher, but not sure how they'd hold up on hot pipes...

I've used those electrician labels on my hot water lines—held up surprisingly well. Just make sure they're rated for high temps. Regular adhesive melts off pretty quick... learned that the hard way.
Those industrial electrician labels can definitely hold up if you pick the right ones. I've used them on boiler lines and heating loops before, and they've lasted years without peeling or fading. The key is checking the temperature rating—usually printed right on the packaging or spec sheet. Look for labels specifically rated for high-temp environments (around 200°F or higher is ideal).
Also, prep matters more than you'd think. Make sure the pipe surface is clean and dry before applying. I usually wipe down with a bit of rubbing alcohol first to remove any grease or dust. Press firmly when applying, smoothing out air bubbles from the center outward. If you're labeling pipes that cycle hot and cold frequently, consider wrapping clear heat-resistant tape around the edges for extra security.
Sounds like you're already on the right track though... documenting plumbing connections can be tedious, but investing a bit more upfront saves headaches down the road. Good luck with it.
Yeah, labels help, but honestly, I've found snapping quick photos on my phone and jotting notes in an app saves me way more hassle later. Labels can still peel or fade eventually... digital backups don't.
Yeah, totally agree with you on the photos. I used to rely on labels too, but after a few years in a damp basement, they were barely readable. Now I just snap pics and scribble quick notes in Evernote—saved me more than once when I had to replace a valve or something. Digital backups are definitely the way to go... plus, it's easier to zoom in on a photo than squint at faded handwriting.
