3)
•
Not enough pressure.
3)
•
Increase pressure if beer runs too slowly.
Correct flow is to fill
4)
•
Defective Thomas and Tongue Vents.
•
Pressure is shut off.
4)
•
Check all washers frequently, particularly the air
vents. A clogged vent will obstruct the flow of air
or Co2.
•
Check source of pressure. Check power source
when air compressor is used. Air compressor
should never be connected to light switch. Make
certain to have a separate electric plug outlet for
the compressor.
•
Check CO
2
tank, if empty, replace (See inside
cover for proper procedure).
•
When barrel is tapped, and proper pressure
applied, pressure must always remain on until
barrel is empty.
•
If beer is started without first applying pressure
beer will be wild at the start, and flat towards the
end.
5)
•
Pre-color, or beer system, too cold.
5)
•
With an accurate thermometer, check
temperature in pre-cooler or box.
•
Temperature at the faucet should always be
colder by at least two degrees than at the
precooler or box.
6)
•
Sluggish pressure regulators.
6)
•
A regular seat, or the regulator diaphragm, may
require replacing.
•
Also, check the same as you would for
Corrections 3 & 4.
7)
•
Contaminated air source.
•
Oil or grease fumes.
7)
•
Filter all air after it leaves compressor.
•
Oil fume from compressor, of kitchen grease
fumes, pumped into beer, will cause Flat Beer.
•
If possible CO
2
gas should be used as a
pressure source.
8)
•
Rapid movement of air.
8)
•
An air fan, or exhaust blower drawing air, or
blowing air, across the bar where beer is drawn,
may cause the dead of foam to fall quickly. Fans
or blowers should be located so that air
movement is not directly across from where
beer is drawn.
LOOSE FOAM
Causes Corrections
•
Large soap-like bubbles (sometimes
called fish eyes). Foam settles quickly.
•
This is generally a Flat Beer condition: the Causes
and corrections for Flat Beer should be followed.
