Random question regarding the Series 4 Kegerator and the smaller 9.5l ball lock kegs:
Is there room in the kegerator to stack two of these on top of each other? More, smaller kegs vs fewer, larger kegs allows for more beer variety chilled and ready to serve.
I'm thinking, buy a bunch of the smaller kegs, split a 20L batch between two kegs, chill and carb up both. One get's removed and put in storage, the other stays in the kegerator. Rinse and repeat.
Not too hard to swap beer and gas lines between kegs to swap over beers. There's gonna be a bit of cross-contamination in the first little bit coming out of the tap, but 2m of 4mm line doesn't hold THAT much beer - about 25ml's by my calculations. Swap the beer and gas lines over, pour yourself a shot glass of mixed beer as a reward for your efforts and then you're right to go.
In theory, you can fit 6 chilled 9.5L kegs into a series 4 and have three on the go at a time and it's maybe a 2-minute job to swap over to a different beer.
Further question, the new carbonation lid for Corny kegs fits on the 9.5l but the plumbing fittings extend past the top of the keg - so what's the height of a 9.5l keg, with the carb lid installed and the liquid in-line connected? Can I fit one of these on top of a normally connected 9.5L keg in a series 4? So 5 beer kegs and a soda keg?
