So yesterday I got my keg king co2 tank back from being refilled for the first time and here's the problem. Even without a regulator attached and just turning the tap on I'm getting nothing?, it's like it's blocked or something?. Yesterday there was a tiny little hiss of co2 when I turned the cylinder tap on, I'd say maybe 1 or 2 psi. Today absolutely nothing. My fridge is at around 1 degree Celsius so it couldn't have frozen the liquid gas could it?. I know the tank is full cause it's bloody heavy!
So what could be the problem?
