How to Remove a Co2 Tank From a Keg

Carbonation from CO2 enhances beer's foam.

Home brewers might prefer to use kegs to store and serve their beer because bottling can be a tedious process. Carbon dioxide, or CO2, is necessary to draw a glass of beer from the keg and can also be used to force-carbonate the beer. While expert brewers generally leave the CO2 tank attached to the keg, you might need to remove the tank in order to have it refilled or to connect it to another keg.

Things You'll Need

• Wrench

Instructions

1. Close the valve on top of the CO2 tank by turning it clockwise.

2. Unscrew the adjustment screw on the regulator. Turn this screw counterclockwise until it will not turn any more.

3. Loosen the regulator nut with a wrench. The regulator nut connects the regulator to the CO2 tank.

4. Separate the regulator from the CO2 tank.

5. Dispose of the washer. You must use a new washer every time you connect the regulator to the CO2 tank.

Tips & Warnings

• CO2 is potentially dangerous.

• If you have difficulty breathing and a headache, you could have a CO2 leak. Close the valve, leave the room and get medical attention.

• Always store your tank upright.

• Keep the CO2 tank away from heat sources.
