Q: Do you have the right type of gas for draft beer systems?

A: Most beer systems run on 60% CO2 and 40% Nitrogen for a proper pour. Guinness and New Castle run on 75% Nitrogen and 25% CO2. However, some restaurants run on straight CO2 and utilize beer pumps. The 60/40 blend can be accomplished in two ways: pre-mixed tanks of 60/40 or a mixer that takes a tank of pure Nitrogen and blends it with your bulk CO2 to accomplish the 60/40 blend. At all times you should carry a backup Nitrogen or pre-mix when using this blend. The beer will not pour if either tank is empty.

Q: Is the gas on?

A: Check regulators in the cooler: anything under 10 PSI means the gas is not getting into the cooler. Typically, there are 3 common problems if the regulators in the cooler do not have pressure.

  • The main tank – bulk CO2 or pre-mixed tank is empty.
  • The secondary regulator – the secondary switch in the cooler may be off. The switch on the secondary regulator should always be vertical; horizontal is off.
  • The Nitrogen tank – the Nitrogen tank is empty. Mixer input-check the mixer pressure. It should be over 40 PSI. The switches on both the mixer and tank should be vertical.

Q: Why is one beer not pouring?


  • Check to make sure it is tapped properly.
  • Check to make sure the FOB ball is floating or reset properly.
  • Follow the beer line up to the wall to make sure kegs are not mixed up. If there is an empty keg on either side of the line that is not working, then this is usually the case.
  • Follow the red gas line up to the regulator to make sure the gas regulator has pressure and the red switch is vertical which means it is on.
  • If there is no success after the above steps have been taken and the beer line is Bud Light or Miller, it is probably frozen.

Q: Why are all of my beers not pouring?

A: Check the regulators in the cooler for pressure and then check all sources of gas for pressure. Change tank if needed.

Q: Why are all of my beers foaming?


  • Pour a beer and take the temperature-temperature should be between 33-38◦ F.
  • Check the cooler temperature. This can only be accomplished properly by getting a liquid temperature, such as in cherries or opening a bottle of beer. The desired temperature is 34-38◦ F.
  • Locate the Glycol chiller. Take the temperature or find the digital readout. The temperature should range from 28-32◦ F.
  • Take the top off and check to see if the pump is recirculating. You should be able to see movement in Glycol bath if this is the case.
