What volume CO2 for Italian Soda?

I just found a site that has inexpensive Toranni 750ml bottles. $4.85 each.

BevTech, Inc.: Torani and Schokinag

So. Now I have the syrup and I need to get crackin on making the water.

I'll use reverse osmosis water from Culligan and I have a kegging system with dual regs for 2 separate gas settings. How many volumes should the carbonated water be? What is typical? 15psi, 30psi?

Also, does one balance the system for soda in the same fashion as for beer?

I run a two faucet tower with beer and soda. I aim for 39-40 degrees and I run beer at 10-12 psi and soda water at 35. We mostly drink the soda water straight or mix it with crystal light lemonade powder . . which makes for a surprisingly good sparkling lemonade (seriously - try it!). 35 psi is perfect for that - where you're just adding powder instead of syrup. My dad just gave me like 25 bottles of torani syrup and I've been making italian sodas lately. You have to add a lot of syrup to make a soda . . and at 35 psi they come out a bit flat. I'll probably move it up to 40 psi.

I don't know how many volumes of CO2 that works out to - the beer tables I've seen don't go up that far.

Yes, you have to balance the system just like beer . . but foam isn't an issue with soda water. When I first hooked it up with 5 ft of 1/4 in line, it would fill a 22 oz glass in about 2 seconds in a quite violent fashion - unless I just barely cracked open the faucet. I now use 20 ft of 1/4 beer line on the soda side and that's perfect.

Right now I have it set to 30psi and will be running through 8 foot of 3/16"ID line. I did a trial pull, pre-carbed, and it flowed out nicely. I'll just have to wait and see how it does with some gas in the mix.

Thanks for the reply.

Ooops - all my lines are 3/16, not 1/4.
