I got my keg hooked up saturday with a fresh CO2 tank and a brand new braggot. Got it going to ~20 PSI. Today I went to test it. Not expecting carbonation yet, but I wanted to make sure it would at least pour, but nothing came out. There is beer in the line but no movement. I also noticed the grey quick disconnect (is that what it’s called?) keeps coming lose, the grey bit that’s supposed to clamp down to the in line post, connecting the gas to the keg. It does not want to stay on the post. Moments ago, it just popped off. The black disconnect stays put securely but the grey one won’t. As I was trying to reset everything, I pulled the vent on the keg lid and CO2 came out, so clearly at some point between saturday and today, some CO2 got in, and it was pouring on Saturday immediately after I set it up.
Is there a way to fix this? Do I need a new gas line? I was hoping to have this braggot ready by this weekend.
