Handy shortcuts for finding plumbing info quick

Honestly, I’m with you on the photos - my memory’s just not that reliable when it comes to plumbing layouts. But I’ll push back a bit: sometimes a quick sketch on paper helps me see the “big picture” in a way a photo can’t. Maybe that’s just my brain, though. And yeah, electrical tape is basically useless after a year... it’s like it melts.

Photos are a lifesaver, but I get what you mean about sketches. When I redid the bathroom last year, I ended up with a pile of phone pics and still found myself scratching my head over where that one random elbow joint disappeared to. Quick doodles on scrap paper helped me see how everything connected, especially when I had to explain to my brother-in-law why we couldn’t just “move the sink over a few inches.” Sometimes, a messy drawing is all you need to jog the memory.

- For plumbing layouts, I like to snap pics *and* draw a rough map. The combo covers me if the photo doesn’t catch a hidden pipe behind insulation or something.
- Blue painter’s tape and a Sharpie are my go-to for labeling pipes or valves. It peels off clean and doesn’t turn into a sticky mess like electrical tape. I’ve learned that lesson the hard way... peeling off black goo from copper lines is not my idea of fun.
- If you’ve got a phone that lets you add notes to photos, that’s gold. I’ll scribble “main shutoff” or “leaky joint here” right on the image, so future me isn’t playing guessing games.

I do disagree on electrical tape being *completely* useless after a year - if it’s a good brand and hasn’t been baking in the sun, it sometimes lasts longer. But yeah, most of the time it’s just a weird, sticky mess waiting to happen.

Honestly, whatever helps you remember is fair game. Some folks’ brains work better with visuals, others need words or diagrams. I’ve even seen people use colored zip ties to mark hot vs cold lines, which is kind of genius if you ask me.

If you’re tackling something big, like a kitchen reno, don’t be afraid to over-document. Worst case, you delete extra pics later. Best case, you save yourself three trips to the crawlspace trying to remember where that mystery pipe leads.

Just my two cents - everyone’s got their own hacks for this stuff.

Painter’s tape and a Sharpie really are hard to beat for labeling - totally agree there. I’ve seen folks try masking tape or even duct tape, but nothing peels off as clean. Electrical tape... yeah, it *can* last if you’re lucky, but most of the time it just turns into that sticky nightmare you described. I’ve had to clean up enough of that gunk to know it’s not worth the hassle.

Photos are great, but they never seem to catch everything, especially when you’re dealing with tight spaces or stuff tucked behind insulation. I always tell people: don’t trust your memory alone. Even a quick sketch on the back of a receipt can save you from a headache later. And those phone apps that let you mark up photos? Underrated tool.

Colored zip ties are clever for hot/cold lines - seen some folks use them for gas vs water too, which helps in older houses where nothing’s labeled. Over-documenting might feel like overkill in the moment, but when you’re staring at a wall six months later trying to remember what’s what, you’ll be glad you did.

Not sure I’m totally sold on the “over-documenting” thing. I get the logic, but sometimes it just feels like extra work, especially for smaller jobs.

- Painter’s tape is good, but if you’re on a tight budget, masking tape with clear handwriting works fine - just don’t leave it on forever.

“Photos are great, but they never seem to catch everything...”

I guess it comes down to how much time and money you want to sink into labeling. Sometimes “good enough” really is good enough.

I get what you mean about over-documenting. For me, it really depends on the job size. If I’m just swapping out a faucet, I’ll jot a quick note on some tape and call it good. But when I had to reroute a bunch of lines under my kitchen sink, snapping photos from every angle actually saved me - found a hidden shutoff I’d forgotten about.
