Just wondering how many kegs everybody can force carb off of a 10 pound co2 tank... It seems like i might have a leak but i can't find it...I'm force carbing [2]-1/4 sankey barrels( 7.75 gallons) and I'm already down to 500 psi...I started out at around 800 psi at 80 degrees and now I'm at 500 psi but the temperature is at 38 degrees.The pressure is set at 27. It's been about 8 hours. should i disconnect and try to find a leak or is this normal??? I don't want to wake up to an empty tank...
