I got started with your Homebrew Keg System with the 5 lb. CO2 cylinder and dual gauge regulator. I bought a two-faucet tower. Now what?

As for the regulator, there a couple of options. The cheapest way is with a CO2 “T”, (order #5301) The only problem here is that if you tap two kegs at different pressures, or release the pressure on one keg while the other is hooked up, you're going to have beer flowing back up your gas lines, and possibly into your regulator, not a good thing.

Our CO2 Distributors take care of this problem by utilizing one-way check valves. These check valves stop beer from flowing back up your gas lines, possibly saving your regulator. They also have a shut off valve, so you can disconnect any keg on your system, or turn the gas off to a certain keg. CO2 Distributors are available in 2, 3 or 4 way configurations.

The best way to provide gas to several kegs is our Double CO2 Regulator (#8011). The Double CO2 Regulator is basically 2 regulators that can be attached to the same CO2 tank, allowing you to set two 2 different pressures for your kegs. You may also want to consider upgrading to a 10 lb. CO2 cylinder, especially if you plan on dispensing three or four beers at once.
