I am brand new to kegging and just bought a kegging set up from keg connection. Today I went to pressure test my system, since the temperature regulator is soon to arrive and I want everything to be ready for that first taste of draft beer.
I have the 3 gauge regulator with 3 kegs. So 1 keg runs straight off one the regulators and the other two run off a manifold. I hooked up a keg to the side without the manifold, brushed soapy water all over the place and everything seemed fine. I went to lube up the seals to the other kegs when I started to hear a hissing sound. Soaped the regulator and a MFL connector was leaking. I tightened that down, turned the pressure back up and I still hear the hissing but there are no bubbles anymore from soaping it. After about ten minutes of soaping up the entire regulator, I still can't get it to show me where it's leaking. (I turned off the valve to the keg by this point so no gas is going over there, it has to be the regulator.) If I turn the pressure all the way down on one of the regulators the hissing stops while the other has pressure. So I figure it has to be that one. I can put my finger over an area where the gauge mounts and can get the sound to change but not stop. I also can't feel any gas leaking.
Can I tighten the gauge down farther? And if so, is it guaranteed that I'll be able to make the gauge face front again? Or is this sound something that just happens and there is no gas leaking? I really don't want to burn through an entire CO2 tank to learn that lesson.
Thanks in advance.
