If you have one hour to spare.
They also talk about nitrogenating beers.

One of the things I found interesting in this video is that they seem to be against check valves on carbonation stones since they make the stones have inconsistent wetting pressures... but what is the alternative? I can't believe that they recommend not having any way to prevent beer back flow into CO2 lines.

The only option is to have a 1/4" shut off valve between the carbonation stone and the CO2 line.

Rig something akin to a plumbing air gap? I suppose putting an empty keg "in line" in between the regulator and the full keg would do that.

I use a shut off valve (no check valve). If someone forgets to close the shut off valve beer will back into the line. But there really isn't any reason to forget (though it does happen with new guys.)
