So I'm finally at the point where I can start kegging... I'm running oxi clean through the tanks and lines and I've noticed that when the liquid runs out, it starts bubbling and leaking air out of the back end of the faucet where I connect it to the liquid line. I thought it was odd when I unpacked it and it was just a metal to metal connection... I would have figured there would need to be an o-ring to seal it. Is this normal?
