Re: Inline Needle Valve Scheme

Hi Cavan,

    I have multiple tanks, in different rooms and on different floors of my
house, all being fed from a single tank and regulator. They are connected
with silicone tubing, and it has worked fine for me.

    I think Outlook Express has messed up your original "drawing" below, but
I believe what you are proposing is the same setup as I am using, with the
exception that I have no needle valve attached to the regulator, but rather
a needle valve for each tank between the tank and the T that feeds it. With
luck my "drawing" below will survive.

regulator-------- T ---------- T ----------------
                  !            !                !
                  !            !                !
                valve        valve            valve
                  !            !                !
                  !            !                !
                  !            !                !
                tank         tank             tank

    One of these runs of line is more than 45 feet; I'm sure that I am
loosing some CO2 through the walls of the line, but as has been said before,
CO2 is cheap! If gas loss was an issue, I think somewhere in the archives
there was mention of someone using 1/8" soft copper for an extended line,
but as I say, the silicone has worked for me.

Have fun,
