The past few batches of brew i have been churning out into my kegs have been great. However after a few days of carbing with my 5lb CO2 tank into my Korney Kegs I notice all of my gas has leaked out. Usually when im putting the gas on I use a spray bottle with sudsy water and spray around all connections to see if there is a tiny leak however it seems as though I never find one. But it never fails when I check on the finished product there is no gas left. Its getting expensive at $18 a pop to fill this bad bear up. Does anyone have any suggestions on how I might go about finding leaks in a more efficient manner and what should be done about "tightening" the whole system down to ensure that my gas goes where it needs to....please help! I have 30 gallons of beer I need to carb up and no gas to do it with as of now......probably wont be able to fill till Monday which puts me behind on other projects.
