|
|
A balanced draft system should pour at the following rates:
(oz/sec - min/gallon) |

|
|
|
_____________ Use mechanical force to propel the beer through the system.
|
Beer pumps

When troubleshooting a direct draw system, if you open the tap and nothing comes out, name two things you should check:
