CO2 System Troubleshooting
Having trouble with your kegerator or other drafting system? Check out this helpful CO2 troubleshooting guide:
|Excessively Foamy Beer||Excessive CO2||Lower the amount of CO2 by turning the regulator adjusting screw counter clockwise. Then pull the relief valve on your keg coupler for about 2 seconds. In a normal keg fridge set up, you should set your regulator between 8 and 12 PSI. Repeat this step if necessary.|
|Worn Faucet Parts||Replace worn washers and seals.|
|Bacteria growth in system, system is dirty||Clean system|
|Dirty System||Disassemble entire system. Clean all surfaces the beer runs through with warm water, soap and a brush. Run line cleaner through your system.|
|Warm Spots in Your Beer Line||All beer line should be kept inside your fridge to maintain consistently cold temperatures.|
|Obstruction in Faucet||Insects and spiders can get up in there. The faucet should be removed, disassembled and cleaned with hot water and a brush between kegs.|
|Improper Pour||Open the faucet quickly and completely. Proper foam should be ½" to 1"high. Wet the inside of the glass before pouring. Lay the beer in the glass by placing the faucet on the inside of the glass. Do not let the beer fall.|
|Old or Improper Beer Lines||Replace old beer lines. If the beer line is discolored, yellow or dirty, it must be replaced. Beer line must be 3/16 ID by eight feet in length.|
|Improper beer or air line. Beer is absorbing plastic taste and odor from the lines.||Use only authorized draught beer line equipment.|
|Not enough pressure||Increase the amount of CO2 by turning the regulator adjusting screw clockwise. Set your regulator between 8 and 12 PSI.|
|CO2 tank went empty||If the keg went flat due to this problem, there is no fix for the beer. Make sure for your next keg all fittings are air tight with proper O-rings and seals. Make sure your regulator has a CO2 tank pressure gauge.|
|Greasy or soapy glasses||Do not wash beer glasses with other glasses that have contained milk, or other fatty substances.|
|Bitter beer, Off Taste, Sour Beer||Beer is too Warm (45%+) or beer is too old. Second fermentation may be occurring giving bitter beer taste, or the beer spoiled.||Keep beer between 35ºF and 40° degrees.|
|Excessively Foamy Beer||Warm Beer||Your keg must always be kept between 35º and 40° degrees.|
|Flat Beer||Beer is too cold||Turn the temperature up. Your keg must always be kept between 35ºF and 40° degrees.|
Keg beer, unlike packaged beer has never been pasteurized. As a result, keg beer is full of live yeast, which gives beer a better flavor, and will turn sour if the temperature is allowed to get over 45° for even a short period of time. A short 15 minute drive in 90 degree weather will bring a keg up to this temperature. Keep them iced!
Keeping your keg at the proper temperature and under the constant pressure from a CO2 system is essentially life support for a keg. Under these conditions, kegs can last several months.
