I want to serve soda through the jockey box for the events and would like to know what the right psi for serving. My soda @30psi can i serve at the same or I need to low it down. The box has 3/8"OD stainless steel coil 50' long.
You might have trouble getting it to go through the lines at anything less than 30. Just adjust your pressure until the flow rate is what you want. For an event, I wouldn't worry about the carbonation changing in the vessel.
