Sharpie and tape is definitely a solid trick—I've used it plenty of times myself. One thing I've noticed, though, is that after a few years, especially in damp basements or humid climates, the tape can yellow or peel at the edges. Not a huge deal, but something to keep an eye on. Has anyone tried using those aluminum HVAC tape strips instead? Seems like they'd hold up better long-term, but I'm not sure how easy they'd be to remove if you need to update info later...

I've actually experimented with aluminum HVAC tape for labeling plumbing lines in my basement, and while it definitely holds up better against humidity and temperature swings, there's a bit of a trade-off. The adhesive on HVAC tape is significantly stronger and more aggressive than regular masking or painter's tape. This means that if you ever need to update or remove the labels, you're likely going to be dealing with leftover adhesive residue or even bits of tape that tear and stick stubbornly to the pipes.
One workaround I've found helpful is to first wrap a layer of electrical tape around the pipe and then apply the aluminum tape label over that. Electrical tape tends to peel off cleanly without leaving much residue, even after several years. This way, you get the durability of aluminum tape without the headache of scraping off adhesive later on. It's an extra step, sure, but it saves a lot of hassle down the road.
Another alternative I've had good luck with is using plastic zip ties combined with laminated tags. You can print out your labels, laminate them (cheap laminators are easy to find online), punch a hole, and attach them with zip ties. They're waterproof, easy to read, and super simple to swap out if your plumbing setup changes. Plus, no adhesive residue at all.
Just something else to consider if you're looking for a more permanent yet easily adjustable solution.
I've tried the aluminum HVAC tape method too, and I agree it's super durable, but honestly, the removal hassle drove me nuts. Even with the electrical tape trick underneath (which is clever, btw), I still ended up with sticky residue here and there. Maybe my basement pipes were just extra grimy or something, but it wasn't as clean a peel-off as I'd hoped.

This right here is exactly what I switched to after my aluminum tape adventure. Laminated tags are great—cheap to make, easy to read even in dim lighting, and swapping them out is a breeze. Plus, if you're like me and constantly tweaking or adding stuff around the house, it's nice not having to scrape off old labels every time you make a change.
One thing I'd add though—if you're on a tight budget or don't have a laminator handy, I've found clear packing tape works surprisingly well as a DIY lamination substitute. Just sandwich your printed label between two pieces of packing tape, trim the edges neatly, punch a hole through it, and you're good to go. It's waterproof enough for basement conditions and costs practically nothing since most of us already have packing tape lying around somewhere.
Also worth mentioning: if you ever need to label valves or shut-offs that aren't pipe-shaped (like handles or knobs), zip ties can sometimes slip around awkwardly. In those cases, I've used twist-ties from bread bags or garden wire instead—they grip better on odd shapes and are still easy enough to remove later.
Anyway, just my two cents from trial-and-error labeling adventures...
I hear ya on the packing tape DIY lamination—been there, done that, and it actually holds up pretty well. Another trick I've stumbled onto is using those plastic keychain tags you find at dollar stores. They're already laminated, easy to write on with a sharpie, and the little metal ring fits nicely around zip ties or twist-ties. Plus, they're color-coded, so if you're a visual person like me, you can quickly spot hot vs. cold lines or main shut-offs.
Speaking of quick ID methods, has anyone tried using colored electrical tape bands as visual markers? I started doing this a while back—just a quick wrap or two around pipes or valves to indicate function (red for hot, blue for cold, yellow for gas, etc.). It's not detailed labeling, but it's saved me some guesswork during late-night plumbing emergencies. Wondering if anyone else has similar quick-and-dirty color-coding hacks...

I've done something similar with colored zip ties—cheap, easy, and they won't peel off like tape sometimes does. I just loop a colored tie around pipes or valves to mark hot, cold, or gas lines. Bonus: they're sturdy enough to last through basement humidity and occasional bumps. Not as detailed as tags, but good enough when you're fumbling around with a flashlight at midnight... ask me how I know.
