My chemistry teacher has constantly told us, never use a carbon dioxide extinguisher on metal fires since they become so hot, that they split up the carbon dioxide molecules. So how much energy/heat (j) is required to do such a thing?
If you don't feel to comfortable with soldering the new unit in you can either 1) hire a professional plumber to install it or 2) use a compression type fitting that requires only a couple of wrenches and some sealant tape to install. Regardless of the installation method, pipe strapping is always a good idea - especially with repairs like this.
