Beer dispenser

Shut of the CO2 tank, then hit the pressure release valve on the side of the beer tap. Make sure there is a grey check valve in the tap where the red hose (co2) is connected. Also make sure the white ball in the tap where the white hose (beer line) is not stuck. You can remove this, it isnt really necessary. Once all checks out, open the tank and readjust the co2 regulator. The reading should not be more than 12 PSI. Everything should work just fine after this. Make sure the glass is as close to the faucet as possible (slanted is better) when dispensing beer. Hope this help :)
