co2 bubble counter & double check valve

so i bought one recently and just got it yesterday. and i installed it to my co2 tank but noticed this morning that there was less water in the bubble counter than i originally put into it.

upon inspection, i saw that water had escaped past the check valve and was halfway to the co2 tank. if it wasn't for the loop i made, it would've likely reached my co2 tank.

is this normal? this is the first time it's happened to me and i'm wondering if i've done something wrong..

Are you using the metal or plastic check valve?

you won't have to look far to see that it's a pretty unanimous opinion to backup the "integrated" check valve on bubble counters with a high-quality check valve just below it. it's certainly what I do.

consider it a $5 insurance policy on your >$100 in equipment (needle valve, solenoid, regulator...)

this Fabco one is the one I use, but I don't expect you'd want to pay for shipping for a single check valve.

the one linked to above is good, too...

what you don't want is

, or

I bought the metal ones from an ebay seller in HK.

I have the solenoid on a timer and when I came back to work the next day the water was almost up and over the loop.

Could it be leaking from the barb fitting if so how would you ensure a tighter seal, the tubing is for co2 usage.

Lesson learned, no plastic cv on a pressurized system, I think that was overpriced too for what u got . You can get metal cv for 4-5 bucks. Put 2 if you want to have a good sleep at night.
