I bought a new 3 tap tower and upon dis assembling to add longer lines and perlick faucets I realized that the shanks that came on the tower are not elbow shanks but just regular shorter shanks. I feel like the bend in the beverage line from a horizontal faucet shank going straight down my tower is going to make a bend where I will end up getting a disruption in liquid flow thus foaming. Does anyone know if it is common practice to always use elbow shanks with a tower or whether the regular shanks it came with will be fine?
