Just an FYI. I have been getting my Powertank refilled at the local dry ice place. They charged $10 for a complete fill...which is 1/2 what the welding shops charge around here. After many refills over the past 18-months I returned for another fill er up. The guy that took my tank this time could not speak any english...and I can't speak spanish...but never thought any different until I realized the next day all the CO2 had leaked out; apparently due to the high pressure valve letting go. I thought their price per pound went up...because he charged me $15...but what really happened is he put about 5lbs more CO2 in the tank than it needed/designed to handle. I guess he couldn't read the label on the side of my tank that states it weighs 16lbs. EMPTY.
Took it to a fire extuinguisher place to have it checked out...they seem to have a much more solid technical background with regard to their employees
...and they had to test the tank, per gov regs, since the pressure relief had blown. So it cost me $30 to find out the tank was fine...and $2 for a new pressure relief valve plus $15 to fill (worth $5 more for peace of mind!).
Anyway just warning others that may be using a CO2 source that might not employ the 'sharpest knives' in the drawer so to speak!
