I hear you on the Dremel—tried that once, and my wrists were shot for days. I’ve had better luck with those aluminum tag labels, crimped right onto the pipe with a zip tie. They’re not pretty, but they stick around longer than tape or marker. Still, nothing survives a new tenant with a can of spray paint and zero curiosity about what “hot water return” means... I keep a binder of printed photos tucked in the utility room just in case. Not high-tech, but it’s saved me from a few wild goose chases when everything else has disappeared.
I’ve run into the exact same issue with tenants—label everything, take a break, come back after a turnover and it’s like nothing was ever marked. The aluminum tags are decent, but even those get mangled or painted over if someone’s not paying attention. I actually tried using heat-shrink tubing with printed labels underneath once. It worked great until someone decided to “tidy up” and cut them all off thinking they were leftover from installation.

That’s honestly one of the most reliable methods I’ve seen. Digital files are nice until your phone dies or you’re stuck with no signal in a basement. I started drawing rough diagrams on the inside of the access panel doors—just a Sharpie sketch showing which pipe is which. Not pretty, but it’s survived more paint jobs than any label so far.
It’s kind of wild how much effort goes into keeping things clear, only for it all to vanish with one round of “improvements.” Maybe there’s no perfect fix, but redundancy seems to help... photos, tags, and a few scribbles for good measure.

That’s actually a solid move. I’ve found that anything “permanent” like Sharpie or even paint marker directly on metal or drywall tends to outlast every fancy label system. One extra step I take: I jot down valve shutoff directions and emergency numbers right next to the sketch. It’s not pretty, but in a pinch, it keeps things safe and clear—especially if someone’s panicking during a leak. Redundancy really is the only way to go... just wish there was a foolproof method.
I did something similar after I bought my place—just scribbled notes right on the wall behind the water heater. It’s not pretty, but at least I know which valve does what when things go sideways. Has anyone tried using QR codes or digital notes for this stuff? I keep thinking there’s gotta be a better way, but paper diagrams just disappear around here...

I’ve run into the same problem—paper gets lost, tape peels off, and marker fades over time. QR codes actually work pretty well if you want something more durable and organized. Here’s a process that’s worked for me:
1. Snap photos of each valve and connection, then label them in your phone (I use Google Photos, but anything works).
2. Create a simple diagram using free tools like draw.io or even just PowerPoint.
3. Upload the diagram to Google Drive or Dropbox.
4. Generate a QR code that links directly to the file (tons of free generators online).
5. Print and laminate the QR code, then stick it near the plumbing setup.
Now you’ve got an always-accessible diagram that doesn’t get lost behind the water heater or smudged by condensation. It’s not foolproof—if your phone dies mid-emergency, you’re still outta luck—but it beats chasing after missing scraps of paper. I wouldn’t say it’s perfect, but it’s definitely an upgrade from scribbles on drywall.
