Yeah, beeswax can be a bit unpredictable for damp spots. I've noticed it tends to soften or even crumble if moisture gets too heavy. Cork's a good shout though—it's not just naturally moisture-resistant, but it also has decent thermal insulation properties. I used cork strips once to label valves in a leaky utility room, and they stayed readable and intact way longer than expected. Worth experimenting with, especially if you're dealing with persistent humidity...

Definitely agree on cork. I once used laminated paper tags thinking they'd hold up fine, but humidity turned them into unreadable mush within weeks... Cork labels were a total lifesaver after that mishap.
"humidity turned them into unreadable mush within weeks..."
Yeah, laminated paper tags seem sturdy at first glance, but humidity always finds a way in eventually. Curious though—did you find cork labels easy enough to write on clearly? I've used cork for insulation and pinboards, but never thought about labeling plumbing with it. Wondering if there's a specific marker or pen that works best without smudging or fading over time...
I've tried cork labels before—writing on them isn't too tricky, but regular Sharpies tend to bleed a bit. Fine-tip paint markers worked better for me, dried quick and stayed readable. Still, cork can crumble over time if handled often...just something to consider.
"Still, cork can crumble over time if handled often...just something to consider."
Yeah, cork labels are handy but definitely not the most durable option for plumbing tags. I've had better luck with plastic key tags—cheap, waterproof, and easy to write on with a fine-tip Sharpie. Plus, they don't crumble or fade as easily. If you're set on cork though, maybe sealing them with a clear coat spray could help? Just a thought...
