If so, "fully" drain ?

c. MAPP more expensive ?

Rather than just give an opinion, here's a recent experience.

I had to replace a faucet bibb on a 3/4" copper line. Cut the old bibb
off. Line had a slow drip that I couldn't stop. Packed a bread in the
line to stop the leak. Tried to sweat the new bibb on using a propane
torch. Tried for over 20 minutes and never could get the solder to
flow properly. Gave up and bought a Mapp gas outfit. Did a perfect
job in about 2-3 minutes.
So it was not a case of impatience - the propane just would not get
the line, bibb. & water hot enough to solder whereas the MAPP did an
excellent job.
