- You are (believe it or not) overcarbonated. I fought this for my first
- couple of tanks. It doesn't take much (overcarbonation) to exhibit the
- symptom you're seeing. The CO2 is coming out of solution as soon as it's
- dispensed.. Do this: Turn off the CO2 feed and bleed off all the pressure
- in the cornelius via the pressure relief. Let it sit for a half day (without
- CO2 applied) and repeat. The next day, bleed it off again and re-apply CO2
- from the tank (about 5 lbs works best for me). Try drawing a beer. If it's
- still giving you alot of head and flat liquid, repeat the above process and
- re-sample the next day. Do this until it gets dialed in. The dispensing
- pressure you use will depend largely on the tubing diameters and lengths you
- use for the liquid line to the faucet.
- It seems that there is enough turbulence and restriction coming up through
- the small diameter draw tube and then through the hose connectors (pin lock
- or ball lock quick disconnects) that the CO2 starts coming out of solution
- as it travels through them... by the time it hits the glass, you can have
- 85% foam and only 15% liquid.
- Bleeding the pressure in steps as I outlined, allows you to stop when the
- carbonation is still quite adequate without excessive foaming.
