CO2 Solenoid

[es88k]

Hi,

I have a set of CO2 cylinder 7L + CO2 solenoid with diffuser.

I am quite sure that there is a leak in or between the Solenoid output and the input of the bubble counter. My cylinder gauge remain unchange when to switched off the system completely. But once I turn it ON, the CO2 pressure drops to almost zero within 1 week when I turn it on (0.25bps at 8 hour per day).

sad that there is no more warranty to the solenoid.

Attached pic that shows the white powder before the inlet to the bubble counter.

Would like to ask if anyone know where can I get it check out to repair? or is it the end of life for this solenoid or buble counter?

Thanks

Have you use soap bubble to detect any leakage? if you are afrait it will spoil the regulator, you can unscrew the regulator and use the soap bubble.

Shadow,

I would like to try out the self test first, but I need a little more info....

"Unscrew the regulator", please help to advise which item you name it as a regulator ? If I were to unscrew it, there might not have any CO2 pressure to "bubble up" the soap bubble. Can you please help me by explain it a little more, so that I can try it out ?

Mike,

Thanks, If I am still not able to at least know where is the problem, I will bring down to NA, I would suppose that NA will have the ability to advise me.

The reason I wants to do all these are:
1) I want to learn
2) The 7L cylinder is too havy to bring around (The actual reason)
But no matter what , I still have to bring it around to refill.....

sorry my mistake, I should say unscrew the solenoid. It is the black plastic thing which red color wording (from your photo). Actually when I test mine I never remove it. I just wrap the solenoid with towel. Purpose is to prevent water ship inside solenoid.

So lets do my usual way .
1. wrap the solenoid with dry towel or anything to prevent soap water ship in. Any excess soap bubble will be absorb by dry towel
2. After you finished wrapping, close the needle valve (small knob near the bubble counter) and open the main valve (the big one on the tank).
3. Apply soap bubble at every joint you can find from the tank to the bubble counter.
4. Turn on the solenoid and check for any leakage

By the way apply also at the round thing that connect the gauge and main valve. That thing is to regulate the pressure, happen to me once, leakage coming out from there.

Clear and understood. Thanks.

Alot of time my job require me to check for gas leak, other than the soap bubble which is the most productive way,do not worry it will not spoil the solenoid as you are just tapping all joint with soapwater(a bit) using your fingers. Another way is by using a flow meter.

Thank you all.

I found the problem 2 dats ago. The O ring is missing. tried to find a match, but cannot find. bought a simple counter to replace.

Refill the cylinder today, pumping CO2 now, should be Ok.....

Thanks for all your help. Lesson learned.
