Engraved tags are a solid idea, especially if you’ve got moisture issues. I tried the colored tape thing too, and it just turned into a sticky mess after a season. Spending a few bucks upfront for something that lasts is worth it, honestly. Sometimes the “shortcut” ends up being more work in the long run...
I’ve run into the same issue with colored tape—looks fine for a few months, then it’s peeling off or just unreadable. In crawlspaces or anywhere damp, it’s basically useless after a season. I started using stainless steel tags with a punch set a while back. Not the cheapest option, but I can still read tags I put in ten years ago, even in some pretty rough spots.
Honestly, I get why people want shortcuts, but sometimes the “quick fix” just means you’re redoing it every year. I’ve seen folks try to use permanent marker on PVC too, and that fades out faster than you’d think. If you’re labeling valves or lines you’ll need to find again, it’s worth doing it right the first time. Saves a lot of headaches when you’re crawling around trying to figure out which line is which in a pinch.
Stainless steel tags are definitely the gold standard for durability, but I’ve had decent luck with a combo approach:
- For spots I might need to change later (like temporary lines), I use recycled plastic tags and a paint pen. Not as long-lasting as steel, but holds up better than marker or tape, and you can wipe it clean and reuse.
- For anything permanent, I agree—go with metal. If you’re worried about cost, check for offcuts or scrap at local metal shops. Sometimes you can get a pile for next to nothing.
- I also keep a rough hand-drawn map of what’s where, tucked in a waterproof sleeve near the crawlspace entrance. Not glamorous, but it’s saved me more than once when I forgot to label something.
Shortcuts are tempting, but those few extra minutes up front really do save a ton of time (and frustration) down the line.
That hand-drawn map idea is underrated—my mentor does the same thing, and it’s bailed us out more than once when tags got knocked off or covered in dust. I’ve tried QR code stickers for a few jobs, but honestly, they don’t hold up well in damp crawlspaces. Ever had issues with plastic tags getting brittle over time? I had a batch crack after one winter, so now I’m picky about which ones I use. The scrap metal tip is gold though... never thought to check local shops for offcuts.
I’ve had plastic tags go brittle too, especially the cheap ones from big box stores. Now I stick to the thicker, UV-resistant ones—costs a bit more but they last. Ever tried using aluminum flashing for tags? I just scratch in the info with a nail and wire them on. Works even in damp spots. Curious if anyone’s found a marker that actually stays readable after a year under a house...
