6) Contaminated air source 
 

•  If possible/applicable, change to CO2 gas as a 

pressure source. 

•  Filter all air after it leaves compressor. 

•  Oil fumes from compressor or kitchen grease 

fumes will cause flat beer when pumped into 

beer system. 

•  Always draw fresh air from an outside source to 

compressor. Attach hair felt filter to the outside 
intake, in addition to filter in line.  

7) Defective Thomas valve (in 

the keg coupler) or tongue 
vents 

•  Bacteria growth may result from beer backing up 

through defective valves and vents in air line. Air 
pressure will then carry this into beer barrel. 

Check and replace defective vents as necessary, 
and thoroughly clean air line. 

8) Unrefrigerated food placed on 

barrel of cold beer. 

•  When unrefrigerated products, such as meats, 

vegetables, fish or fruits are placed on barrel of 
cold beer, the beer becomes warm long before 

these products chill down to the cold 
temperature. This change in temperature will 
cause cloudy beer. 

9) Sluggish pressure regulator 

•  Repair or replace the regulator as necessary. A 

regulator seat or the regulator diaphragm may 
require replacing. 

10) Moisture in air system 

•  With the use of an air compressor, it is 

imperative to have a moisture trap installed in 
the pre-cooler, and drained daily. This is in 

addition to an activated charcoal filter, necessary 
to purify the air just before it enters the barrel. 

•  With tank type compressors, drain the tank 

weekly. 

•  Moisture traps should be drained daily. 

11) Drafts 

•  Rapid air movement, caused by an air fan or 

exhaust blower, drawing air or blowing air across 

the area where beer is drawn may cause the 
level of foam to fall quickly. Redirect air flow so 

that air movement is not running directly across 
area where the beer is drawn. 

 

Beer has bitter and unpleasant odor or taste. Sour beer may taste and smell extremely 

yeasty or moldy. 

1) Improper or lack of cleaning   •  System should be cleaned at least every two 

weeks with an approved cleaner 

•  Coils should be thoroughly cleaned at least once 

every week or two. 

•  Brush and clean faucet.  

•  Taps, rods, and tap-Seal fitting should all be 

scoured, using a detergent, then rinsed clean. 

•  Direct draw systems must be cleaned the same as 

coil systems: 4 feet of direct draw line 

accumulates as much per foot as any other 
system.
