If there is a soldered joint near the joint you want to remove, use a cloth, towel, any rag, soaked with water and wrap that joint. Heat that gets to the joint will be expended heating the water or steaming it. Of course, use caution in not torching the rag. It’s like having water in a pipe which you can’t solder because the heat is steaming the water and the joint can get hot enough for solder to melt.
If the solder won't melt, you might have water remaining in the pipe or your torch might not be getting hot enough. Make sure to drain the pipe fully and try again. You might want to consider a hotter torch, I like the Turbotorch TX500 series but Bluefire makes a great budget friendly option for occasional use.
You should use a torch that uses a hotter flame than common propane, like a MAPP (methylacetylene-propadiene propane) gas torches. MAPP comes in a yellow cannister.
I believe MAPP gas isn’t made anymore; the yellow canister is MAPP branded canister and just a fuel not much different than propane. I haven’t researched it, but I’ve seen this from a credible source.
Just a normal propane or MAPP gas torch. I recommend TurboTorch, they are high quality but expensive. I bought mine from a local plumbing supply store.
The more solder you can remove the better but it's hard to remove. It's a lot of extra work that you don't really need to do as long as it's prepped properly.
@@DragonBuildsbe careful that MAPP gas is being sold as a brand rather than a mapp fuel. If there’s a hotter burning fuel, it’s likely a pro sourced canister that is sold for $10 in improvement stores.
