I have a corny keg full of cider that I started carbonating today. At first I hooked the CO2 up to the OUT post because I've read it carbs quicker since the gas will travel through the liquid rather than sitting on top. I used my white gas-in adapter on the liquid-out post and it instantly foamed out all over the place. Luckily I had a towel handy. I had some trouble getting the adapter off of the keg post, it just didn't fit well.
I connected the gas to the correct post and everything it going well. But I looked closely at my other keg and it looks like both posts are shaped the same. Do I have a bad Out post on my keg? I can't test it now because the keg is under pressure (I should have tested my black adapter before I carbed it, but I'm just not that bright).
Should I be worried about dispensing this, or are the adapters specifically meant for each post?
