I built a keezer with a 2 faucet tower using a kit from beverage factory. It came with 5ft 3/16 ID beer lines, Kegco LH-542-2 Pro Series double gauge regulator, and standard faucets. From day one (4 yrs ago) i have been dealing with this foam issue. I go to pour a the first beer after being idle for a while and open the tap to clear flowing beer for about 1-2 seconds followed by a short burst of foam and then clear flowing beer again. Every beer after that is foam free. I typically have my pressure set to 10 psi. First i thought it was a temperature problem but cooling the tower did nothing. Then i installed a large cpu fan to move the stagnant air around... no help either. Moving the pressure up and down doesn't seem to help either. So i started looking into the balancing of my system. I am just lost though. If i follow the calculation it seems i need to shorten my line to 4ft.... but all i read is people recommending longer lines. Im trying to target 2.6 volumes of CO2 at 38°F. According to the chart I should be applying carbon dioxide at 12.4 psi. My faucet is about 2.5 feet above the center of the keg so that should add 1.25 psi of resistance. My 5 foot 3/16 ID beer line should add 15 psi of resistance totaling 16.25 psi.... so i am unbalanced? Is this causing the burst of foam? Or should i be looking at temps again? I have grown used to just wasting half a beer at first pour but guests don't. Im tired of wasting beer.
