CO2 help

[go14344]

when i turn on my co2 tank, after few hours, the bubbles will stop or no more co2 injected to the tank... is my regulator defect?..

If the tank isn't empty almost empty, there should be a choke along the line. Check each one separately to isolate the choke.

ill check the line.. bt the tank has 1000 psi..

care to tell us more about your co2 system? do you have a needle valve or solenoid valve or bubble counter?
how are you controlling your co2 bubble rate?

[ongtw]

did you turn on only the regulator or both regulator and the tank? (there's the knob on top of the tank which you will need to turn on)

dismentle the co2 set, and reset up the set piece by piece and test it to find the fault. you should be to identify the problem this way.

if you can, you should take photo of your regulator. Normaly happen with manual regulator

I recently happened to have the same problem too.I am using a manual regulator,check valve and bubble counter.No needle valve here.After a few hours the CO2 injection will stop.Then I'll adjust the bubble rate to get it going again and the process repeats itself.Very frustrating.What could be the problem?Will changing to a solenoid valve help solve the problem?

Thanks in advance

yes it will. My guess, it is not the solenoid that helping, it is the needle valve and the thing that regulate the pressure (don't know what you call it). Anyway there should be 2 pressure gauge, one for the tank pressure (~1000psi) the other one is the output pressure (~50psi)

heres my co2 set up... main tank ---> regulator ---> needle valve ---> solenoid ---> check valve ----> co2 reactor with bubble counter.. bubble rate, by turning open the needle valve...

both are turn on..

not sure if this matter, usually solenoid first follow by needle valve

[tawauboy]

usually the needle valve is connected after the solenoid. solenoid is after the regulator. you must be using some sort of valve fittings to enable the solenoid to be attached to the output of the needle valve.

why don't you remove the solenoid valve from your setup and try again.
turn on the main cylinder valve by 1/4~ 1/2 turns.
adjust needle valve to desired co2 bubbling rate.
