That should work great! I never once thought of using PVC for CO2 plumbing, except for reactors. You can't get much easier to make than that, if you have those bubble counter/needle valve combos.

What bubble counter solution are you using? Water keeps evaporating...half water half glycerin?

I'd be concerned about leaks... How exactly did you connect the bubble counters to the pvc pipe?

The PVC was drilled and tapped, only ran tap half in to get a tighter seal with the needle valve. Threads are coated with loctite at almost all my CO2 connections. Haven't had any leaks since I started using loctite.....DC

Thanks, makes sense. Can you share where you get the needle valve/bubble counters?

Water doesn't evaporate from bubble counters. I have a DIY bubble counter here at the house that has been going for over 3 years. It might have dropped a couple of mm in water depth in that time.

Look closely at your bubble counter. Ask where the water is going. It's not evaporating. The only exception to this would be if the bubble counter is mounted on a all-in-one and the solenoid is heating up the water to the point it is evaporating.

Thanks Rex. I'll check up on it. They're mounted on a metal manifold coming from a JBJ regulator.

Nice DC,
I've seen PVC used for air-manifold to run racks with corner bubble filters, but never thought about using CO2 with it.
Way to go out of the box.
