Re: [APD] Inverting CO2 tank
Running an outlet tube up past the tank and putting the
regulator on the end of that is one way to keep the
regulator up above the tank.
But hey, have you guys laid a tank down to see if what you
are saying is true? That the regulator freezes and and the
CO2 doesn't flow right, etc.?
Try a little empircism; you might be surprised.
