I am looking to avoid adding a manifold to my (at this point still conceptual) kegerator interior for aesthetic/clutter reasons. The setup will include a primary regulator and two secondaries for three kegs (allowing independant pressure settings for each keg). I will have a CO2 tank with a standard primary regulator outside the kegerator, and will run the gas in through a single bulkhead.
: Once the gasline is inside the kegerator, I could run it straight into a 2-way manifold. One output from the manifold could then feed the first keg (which would get whatever pressure the primary regulator is set at) while the second output would feed into the two secondary regulators (which would then feed the other two kegs).
: Instead of using the manifold, could I instead run my gas line straight into the secondary regulator (right side of pic), remove the plug from the pass-through on the last secondary regulator in the chain (left side of pic):
And then attach a shutoff valve like this to the open pass-through on the last secondary regulator, which would presumably still be outputting CO2 at the PSI set on the primary regulator?:
If this works, it would allow me to run three kegs at three different pressures without requiring use of a manifold (with a bit less metal cluttering up the inside of my kegerator, and saving me a few bucks as well). But I'm guessing there's a catch, so I thought I'd check if anyone else has tried it first!
