Heat’s always a gamble, especially with older plumbing.
I get where you’re coming from, but I’ll admit I’m a bit more bullish on using heat—just with some caveats. A little torch action can work wonders on those stubborn stems, provided you’re careful and know what’s behind the wall (and have a fire extinguisher handy... learned that one the hard way). The trick is to keep the heat localized and not go overboard. That said, I’ve had PB Blaster do absolutely nothing on 40-year-old threads—sometimes it just laughs at me and keeps everything fused solid.
Strap wrenches are great for chrome or delicate finishes, but if you’re dealing with something already chewed up, channel locks with a rag can give you that extra bite. Just don’t go full gorilla or you’ll be shopping for new trim. Patience is key, but sometimes a little calculated risk pays off—otherwise some of these jobs would never get done before lunch.

- Totally agree with “sometimes it just laughs at me and keeps everything fused solid.” Had a shower valve once that wouldn’t budge no matter what I threw at it—heat finally did the trick, but yeah, nerves were shot.
- PB Blaster's hit or miss, for sure.
- Good call on not going full gorilla with the channel locks. I’ve learned that lesson the hard way—stripped a stem and had to run out for a new one.
- Sounds like you’ve got the right mindset: patience, the right tool, and a little guts when you need it. That’s how you get through these old houses.
I get the appeal of heat, but I’m always a bit wary—especially in older houses where you never quite know what’s lurking behind the wall. One time I tried it on a 60s-era stem and ended up softening some ancient solder joints nearby... not fun.

Couldn’t agree more there. Honestly, I’ve had better luck with a proper stem wrench and patience than with brute force or heat. Sometimes just walking away for an hour does more good than another round with the torch.
- I get the caution with heat, but honestly, sometimes it’s the only thing that’s worked for me—especially when PB Blaster and patience just aren’t cutting it.
- That said, I always keep a spray bottle handy in case things start to get sketchy behind the wall.
- Stem wrenches are great, but if the thing’s fused from decades of mineral buildup, a little controlled heat can save hours (and my knuckles).
- Just gotta weigh the risk... old plumbing is always a gamble, right?
I get what you’re saying about heat—sometimes it really is the only thing that’ll budge those old stems. Still, I always worry about what’s lurking behind the wall, especially with older copper or if there’s any old solder joints nearby. I’ve heard stories of folks accidentally melting a joint and not realizing until there’s a slow leak days later. That’s my nightmare scenario.

Have you ever run into hidden damage after using heat, like scorched insulation or anything weird behind the wall? I’m always torn between risking a little heat and just biting the bullet to call in a plumber (which isn’t cheap). Is there a way to tell if it’s safe to use heat in a particular spot, or is it just cross your fingers and hope for the best? Sometimes I wonder if I’m being too cautious, but with my luck, I’d end up with a bigger repair bill...
