Single Regulator to dual regulator system?
« on: July 17, 2018, 01:57:03 AM »
I have a single regulator for one keg, we recently upgraded to 2 keg's for drinking purposes (lol) but are unclear what we would need to set our system up to carbonate each keg's to different volumes. How would we go about setting this up to get to our goal? We have an extra regulator also, so could we just get some sort of connection post and take off the part of the regulator that shows the co2 tanks volume? Any help would be greatly appreciated!

The high-pressure gauge won't do any harm as a secondary, it'll just read near zero. All you have to do is remove the tank fitting from the regulator body and replace it with a barb or flare fitting to match your setup. Although without heavy-duty plumbing tools that can be easier said than done.

Don't remove the high pressure gauge on your second regulator.  Connect the gas line out from the primary regulator to a two way gas distributor.  One line out of the distributor will go directly to the gas quick connect fitting of one of your kegs.  This line will supply gas at the pressure of the primary regulator.  The second line out of the distributor should go to your second regulator.  You can set this regulator lower than the primary but not higher.  Connect the hose out of this regulator to your second keg gas quick connect.

Are you saying that I can daisy chain regulators through the useless secondary gauge?  that is friggen awesome.

Not exactly. Well, maybe. What's the secondary gauge?

Code: [Select]
CO2 Tank - primary regulator - T - (switched fitting) - secondary regulator - keg

Google co2 tank male to hose barb. This fitting will allow you to connect your second primary regulator to the gas line out from the 2 way distributor.  I wouldn’t mess with the bottle pressure gauge.

To help with google, the tank fitting is called a CGA-320.

A couple of people have already talked about the configuration of a second regulator, so I will not repeat this.

A word of safety is warranted here.  DO NOT use something anything that is not high pressure rated to connect regulators together at the high pressure gauge point (the place where the 1000 lb gauge is located on the first regulator).  First of all the high pressure gauge is normally left hand thread an the outputs are right hand thread.  Secondly, something like threaded brass pipe (which I used to connect a very low pressure gauge)) is only rated for a couple hundred pounds of pressure and the output from the CO2 cylinder can be in the vicinity of 800-1000 lbs.  This could result in a catastrophic explosion of the non pressure rated pipe on a high pressure connection.  Be careful, don't connect anything to the high pressure gauge port other than a high pressure gauge.  Alternatively, buy a double gauge assembly from a LHBS or a mail order homebrew shop to be totally safe.
