Regulator Probs ?

[pretzel]

Hooked up my co2 to my keg 3 days ago and set the regulator to 10psi, walked out to the keg the next day to find the regulator at 0, turned it up to 10psi again, walked out today to find it at 0. I pulled the air valve and there is still pressure, but very little. I have pulled the regulator off and opened the valve and there is co2 that comes out. My only guess is that my tank is on the low end. Any thoughts on what is going on?

Does'nt your regulator have a dial meter on it that tells you how much gas you have left? If not I strongly suggest you invest in one, you can get the meter alone and most regulators have a spot to install one. If your not low on gas it sounds like there is a leak somewhere.
