Steel wool’s a classic, but honestly, it does rust out over time—especially anywhere with a hint of moisture. I’ve seen mice just push through the rusty stuff after a year or two. I usually go with copper mesh instead. Costs a bit more, but it holds up and they hate chewing it. As for boilers, tracing leaks is just part of the gig… but labeling pipes when you first install or service them saves a ton of headaches down the road.
I get the copper mesh thing, but man, last time I tried it, I ended up with little copper strands everywhere—felt like I was fighting a glitter bomb. I still use steel wool, but I spray it down with a little WD-40 first. It slows the rust, and so far, the critters haven’t figured it out. As for pipe labeling... I always think I’ll do it and then forget until I’m knee-deep in mystery pipes. Every. Single. Time.

Yeah, labeling pipes is one of those “I’ll get to it next time” jobs that always bites you later. Been there more times than I care to admit. Here’s what’s worked for me, step-by-step, after too many rounds of tracing mystery lines:
1. Grab a roll of painter’s tape and a Sharpie before you even start. Don’t wait until you’re done—label as you go, even if it feels silly.
2. For anything permanent, I swap to zip ties with those little write-on tags once I know what’s what.
3. If you’re dealing with old pipes, take a quick photo with your phone and write notes on the pic later. Sounds tedious, but it’s saved me hours when something leaks at 2am.
4. As for the steel wool and WD-40 trick, I’ve done it too, but I’m always a bit skeptical about how long it actually holds up. I’ve had mice chew through both after a season or two, so I started stuffing a bit of expanding foam behind the mesh for extra insurance.
Not perfect, but it’s kept me out of too many late-night “which pipe is this?” situations.
Couldn’t agree more about labeling as you go—saves a ton of headaches later. I’ll add, if you’re working in a tight crawlspace or somewhere you can’t see well, those cheap colored zip ties are a lifesaver for quick ID. I’ve tried the expanding foam trick too, but sometimes it gets messy if you ever need to redo something. Honestly, nothing beats a good old-fashioned diagram on the wall nearby. Might look a bit old-school, but it’s saved me more than once when memory failed.
Colored zip ties are a game changer, especially when you’re in a cramped spot and can’t see squat. I’d add that using a label maker with heat-shrink tubing is worth the extra effort—those paper tags just get wrecked over time. Diagrams are solid, but I’ve noticed if you update something and forget to change the drawing, it’s almost as bad as not having one at all... learned that the hard way.
