Just planning my setup for a kegerator. Based on other's experience I'm going to use 4mm (approx 3/16") beerline. The taps Im looking at are 7mm (1/4") and 10mm. I can buy the appropriate adaptors from tap threads to connect the hose.
My question is will that cause any problems to change the size there at the tap? It seems like sizing up just before the tap would cause some turbulence and possibly foaming, or am I just worrying for nothing. THanks guys.
