Lesson learned! Bought a 30 pony bottle.

#5) I'd shut it down and breath the pony. It keeps the tank from getting water in it as well. It's likely to warm up in a few minutes and start working later thus saving the air. You should be able to shut down a tank in 10 seconds.

Breathing from a freeflow for any time will also freeze your lips and that sucks as well.
