Sweating pipes and valves

I have never used map gas and have only used propane. I didn't know if it is a bad choice. Years ago I was trying to soldier a 1" line to repair a leak in the yard and propane wasn't doing the job. I had to get an AC buddy to bring over his acetylene torch and it did the trick. Another reason is I could use map gas to help with sturborn bolts too. I agree, prep is important, but sometimes having some extra heat coild help.
 
New quarter turn valve has been sweated on and no more leaks. Now I have everything I need to do the others if they start leaking.
 
Did you pull the valve apart to not hurt it with the heat?

At work, I only use map it I need the higher heat for sweating copper lines that is attached to cast iron or to steel. Other than for that I use propane for most everything.

I thought about it but after reading the directions 5 times on the package and on the manufacture's website, it did not mention that being necessary. Am I asking for trouble?
 
It's always best to pull the valve apart.
Solder melts at 370*
Hot water runs around 120-140*
