What an astute observation . Your insight saved thousands of lives # forsen 1 <| sep |> I actually thought the Momentum would have a worse sound for being a more portable option . Is it really better than the HD 598 C and the HD 598 , for that matter in terms of sound ? Could you delve a little deeper into that part ? <| sep |> got movember korb . <| sep |> Why not get a secondary regulator ? So basically take the hosing that comes out of your regulator now and put a stainless steel T j o i n t s t a inlesssteelchooseyoursize in it . Run one end to whatever keg you want to carbonate , and run the other line to a secondary r e g u l a t o r b o d y s e c o n d a r y r e g u l a torchoosetapriteorchudnow . That would solve your problem far easier than trying to fit another co 2 tank in there . Leave the pressure at 30 psi on the regulator hooked to the tank , and set the secondary to whatever serving pressure you like . Edit plus with the secondary regulator , you could mount it somewhere that is easier to change the pressure .
