What is the liquid temperature and brand of beer? If it is 38 degrees F the pressure should be approx. 14 Psig. For Coors products 16 PSIG. For every one degree warmer, adjust pressure up one pound. Even with the correct pressure, the initial pour will be foamy due to temperature difference behind shank. Beer will eventually clear since colder beer from keg is chilling line. When this foam comes out of faucet into glass, stop immediately and dump. Then try to dispense. It is very difficult to pour clear beer on top of foam. A blower and flex tube routed into tower will correct this.
