- I’ve had the same issue with Sharpie smudging under packing tape, especially in the basement when it gets humid. Sometimes it actually blurs so much you can’t read it after a year or two.
- Tried those pipe label kits once—honestly, they work but feel a bit overkill for a small setup. Plus, I always lose half the stickers before I finish labeling.
- Following the pipes was wild. There was a random loop that didn’t seem to connect to anything useful. Ever find weird “dead end” pipes when you were tracing yours? Makes me wonder what the original installer was thinking...
- Sharpie under tape is a pain—I've switched to paint pens for that reason. They hold up way better, even in damp basements.
- Label kits are nice in theory, but honestly, masking tape and a bold marker have lasted longer for me than the fancy stuff.
- Dead end pipes? All the time. Sometimes they're leftovers from old systems or abandoned upgrades. I always double-check they're not live—never assume they're capped safely. You never know what someone did before you moved in...
Paint pens are a solid upgrade—I've seen Sharpie labels fade out in a year, especially if there's any moisture around. I still use masking tape and a fat marker for quick jobs, but for anything I want to last, paint pen's the way to go. Label kits look tidy, but half the time the adhesive gives up before the tape does.
Dead ends are a headache. I can't count how many times I've opened up a wall and found a random capped line, sometimes with water still in it. Always test before you cut—I've seen folks get a nasty surprise thinking a pipe was dead, only to find it still pressurized. Sometimes you can trace them back, sometimes it's just a mystery. Old houses are the worst for that... you never know what you'll find tucked behind the drywall.
Paint pens are a game changer, especially in basements where moisture just eats up regular marker labels. I’ve had to redo so many faded Sharpie tags over the years, it’s not even funny. And yeah, dead ends… total nightmare. Once found a capped line that still had pressure—took a bath I wasn’t planning on. Old houses keep you guessing, that’s for sure. Sometimes I think previous owners just liked to mess with us.

That’s the worst. I’ve run into a few “mystery pipes” that looked abandoned but still had water or steam behind them. Always double-check with a gauge if you’re not sure. I agree on paint pens—oil-based ones last way longer in damp spots. For labeling, I sometimes wrap clear heat-shrink tubing over the tag for extra protection. Old house plumbing is like a puzzle where someone threw away half the pieces...
