Troubleshooting Guide

CO2 escapes immediately when
attaching cartridge
• Tighten retaining nut (might be reverse threaded)
• Make sure cartridge is proper size
8g = 63.5mm – 66mm
16g = 87mm – 89.5mm
• Make sure regulator dial is off (turned all the way
counter-clockwise)
• Check cartridge seal for damage
• If still leaking, remove retaining nut, cartridge seal, and
piercing pin – check piercing O-ring for damage
• The cartridge sleeve does not need to reach the end of the
threads (bottom out)
• A 1mm to 2mm gap between the sleeve and the cap is normal
Foamy pour
• Beer has been shaken during transport and needs to sit for
about 10 minutes before pouring
• Beer has warmed up and needs to be cooled down before
pouring
• Beer was lled from a tap system with >15psi
• If beer is foamy only after a few pints, the sight tube may need
to be replaced
• Upper gooseneck seal may need replacement
Pressure Gauge isn’t working
• Tap gauge rmly while pressurized
• Remove pressure gauge and soak in hot water with baking soda
• Using a pin, poke the rear pressure hole to clear any debris
Tap leaks constantly even when locked
• Tap assembly may need cleaning
• Tap shuttle O-ring needs to be replaced. (-110 O-ring)
• Make sure regulator is always on (turned clockwise)
• See tap maintenance video at www.growlerwerks.com/howto
uKeg does not hold pressure
• Cap O-ring may be too loose or damaged and needs replacing
• Make sure regulator is always on (clockwise)
• Cap may be on too tight – only a rm hand tightening is needed.
• Cartridge seal may be damaged, see “CO2 escapes immediately
when attaching cartridge”
