Two Tap Kegging setup Question

I just got a Kegerator with a double tap and I plan to use 2 5 Gallon kegs.  Is it best to use one C02 bottle with a double regulator set up or two seperate C02 bottles and two regulators?

You only need one tank to carbonate and serve your beer. You’ll want an adjustable regulator with at least two dials- one that shows the serving psi and the other the total amount of psi in the tank (which tells you how much gas is actually in the tank).

The cheapest and easiest setup would be one CO2 bottle feeding a single output regulator, feeding a dual output manifold.

This is what I have for four taps.

I agree…this is the best way to go as long as you don’t mind using the same psi for all your kegs

I think this is an important point - if you want all of your beers to have the same CO2 level, then one secondary regulator for all of your kegs is no big deal.  If you want to have different CO2 levels for different beers, you need a secondary regulator for each different psi setting.

And probably a longer line for the tap you want to serve a higher PSI beer out of, right? Otherwise, you’d get pretty foamy pours on that tap, I’m thinking.

Yes, exactly, you need to balance each line in the system.  If they are all on the same psi, same shanks, same taps, same line, same length.  If you change the psi or one of the other variables then you need to recalculate.  Higher psi means longer lines, all other things being equal.

Has anyone used taprite 741 regulators, I have two and want to forge them into 1 dual regulator. One line to carbonate at a different psi and one split to push 2 taps (I fit 3 corneys in the keezer and have two taps).

Also whith kegging?  Should i turn off the C02 tank if the beer on tap is not going to be used for a week or so or should you keep the C02 tank open?

I keep my tank open. It’s not a problem as long as your CO2 system doesn’t leak (and if it does, you should just fix the leak).
