Actually, due to a bad habit of procrastination, I've had my CO2
bottle running "on empty" for the past 2 weeks. Amazed it's
still got any CO2 in it. Tank pressure is now down to about 300
psi, and the flow from the needle valve is still RELATIVELY steady.
I think the bubble rate increased a tiny bit, but not enough to really
see a change in the CO2 level, or the pH.
And mine is most definitely a cheap beer regulator. Saw the exact
same one in the welding supply place for $30.00. They stock them
for all the home-beer people that come in looking for CO2 gear.
