I have a 3 tap setup on my kegerator and a 3 way gas manifold that runs off of my 5# tank.
I think I picked my splitter at Kegconnection - it works great. I close 2 valves when I am force carbing, drop the pressure to serving and can serve 3 beers at once with no issues.
Ergo Bibo Sum - I drink, therefore I am.
Eggo Bibo Sum - I drink, therefore I waffle.
