Looking for input regarding kegging, just kegged my first homebrew and the beer is slowly getting carbonated but it seems my co2 tank is emptying faster then I expected. I set my regulator to the desired setting and just left everything open. I'm wondering if maybe I should just pressurize keg then close the valves? I checked system for leaks with soapy water and seems OK. I do smell an odd oder inside keezer though. I am going to check ball lock fitting at the keg to see if maybe it's faulty. Cheers.
