How do you know only 40% is left? The gauge attached to the cylinder shows the pressure level rather than the Co2 quantity.

Did you test for leakage of the regulator assembly? Chan will usually tell you how to do it.

Did Chan fix the stuff up for you? He fix it for me the last time I bought a 5 litre tank from him...no problems..![]()

can you kindly tell me how to test the leakage..thanks[:]
Hi plant talk, why don't you bring the CO2 tank to Mr Chan?
You can test leakage by using soapy water...but using water on the regulator side isn't advisable though...best is to bring it back to Mr Chan as wks said.

mine is a taiwan co2 tank and a Italy sol,can you kindly tell me where to apply the soupy water..thanks![]()
It's better to bring to Chan after you have verified there's a leakage. One or two gauge? What's the reading guage in psi? On one of them, the reading should be around 900 to 1000+ psi if your tank is full.
Test your CO2 piping for leakage first, cos it's the easiest. Do this while your solenoid is on. Dip the entire bubble counter and check valves setup into a container of water and look for escaping bubbles. Be careful not to wet the solenoid.
Testing regulator for leakage:
1. Disconnect the solenoid from the power source.
2. Open the main valve (the big round tap at the top).
3. Wait a few seconds, then close the main valve.
4. Note the reading on the guage.
5. Leave the solenoid disconnected for 24hrs.
6. At the end of the 24hrs, check the reading again. If it has dropped, then there is a leak on your regulator.
Chan will help you if he can, but you need to verify there's a leak and the location of the leak. It's not something that he can easily check on the spot.

Soapy water is usually applied to the joints to test for leakage but it's not very thorough as you might miss an unseen joint. My regulator sprung a leak inside the guage and there's no way soapy water would have detected that.
When you apply soapy water, if there is a leak, you will see a bubble forming at the leak location.
Try the method I listed above to test the regulator. That will tell you if there is even a tiny leak. Then use soapy water to find the location of the leak if there is one.

Actually Chan told me to use the method that vinz is recommending to test for initial setup leakage....Didn't he told you to check "plant talk"? His method is much simpler I guess...open the main valve ..the pressure gauge should give you a reading...off the main valve...after 24hrs if the pressure gauge shows same reading..the regulator side is fine. []
Oh..by the way..did you open your needle valve all the way????? Hope not I guess...should be a leakage on the regulator side cause the line side should not cause such a big drop in CO2 level.

Thanks vinz, thanks you so much with all your kind advises, i will try that out![]()
Does it mean that i must open the main valve with the power on ..then the pressure gauge will give me a reading...off the main valve for 24hrs n check the reading again.![]()
Don't just thank me leh... the rest also help what. []

No, no, no. Power off the solenoid before the test and leave it off till after the test. The guages do not need power. Read my instructions carefully, leh.

Nope you do not need to "on" the solenoid for the method Chan taught me ..that is if you are just testing the regulator side..you just need to open the main valve so that the CO2 can get into the regulator and register a pressure reading on the gauge. After that you can "off" the main valve and wait for 24hrs to see if the pressure drop..if it does not drop..then it is a OK~. You need to "on" the solenoid only if you suspect the solenoid valve is not closing properly..and not for 24hrs lah...just on it and bubble it into a cup of water..then "off" the solenoid and check after 4-5hrs later to see if there is still bubbling..cause you need time for the remaining CO2 in the regulator to clear. If after 4-5hrs there is still bubbling..then suspect something is wrong with the solenoid valve.

Thanks again to all ppl who have given me their advises.This evening I will try out all the ways to test the system[:]
