What do I do if Highballs are pouring with excessive foam?

Answer: The keg may be over-carbonated and/or the CO2 pressure is not balanced. First, ensure your PSI is set to 1 PSI per 1 foot of hose line. If this does not resolve the issue, disconnect the keg, release the CO2 pressure, remove the lid, and allow to sit for 30 mins. Lastly, reattach the lid and reconnect to the draft system.
