Sharing CO2 between two tanks

Overgrowth · 12-08-2012, 06:56 PM

Could I use a T-Valve or a gang valve to split the CO2 output? I know you're supposed to use a dual stage regulator with two needle valves, but I really don't want to spend any more money.

I won't work very well. You probably won't get an even split between the two. The gas will fallow the path of least resistantance.

yup you have to use two needle valves and bubble counters

+1. You will need two needle valves.

That's what I thought. Oh well.

You could make an in-line manifold with smc needle valves for about $25. That's about as cheap as you could do it with 1/2 way decent parts.

any leads on where to source these parts?

You can get a T from your local hardware store.

The needle valves will have to be sourced online, most likely.

Yep, a manifold is pretty cheap. Needle valves should range from $5-$8 on eBay. Sometimes I've seen them at 5 for $15 as a package deal.
