I'm new here. Just kegged 10 gallons. 2 five gallon corny kegs. The cooler is set to 40f and I have 30 psi on 2 kegs. The regulator seems to be dropping kind of quick. May be 10 lbs so far. I checked for leaks and don't see any. Am I doing something wrong. Just want to make sure I'm not wasting co2.
