its is off, just that the pressure inside the air tube need to equalize ( as in expel excess CO2 in the tube )
Hi all
Just to check with you guys, after switching off your electronic solenoid does it take 30min to 1 hr to become totally off?

As eviltrain said, there is still pressure in the tube but I do not think it will last for 30 minutes

sound like something stuck, maybe due to the missing screw thus the solenoid not alight properly. Bring it to NA or Bioplast, they normally can help.
Yah. Bring it down to na and they will troubleshoot for you
Hi. I do have similar prob. The bubbles still coming out even if it is off.
Is it advisable to troubleshoot ourselves?
Or does anyone know how much NA charge for repair?
Thanks
Besides that, I have a manual CO2 regulator but the valve is very insensitive.
I am thinking it's due to the long time usage.
Does anyone can advise if it is possible to improve the sensivity if I troubleshoot on my own?
Dont think its advisable for us to troubleshoot on our own. You never know what to expectin the event a badly done job. Note this is a high pressure tank we are handling. Pay a small fee to get a proper job done, if its too expensive then you may consider getting a new solenoid.
I think for a good working solenoid it will off totally when you switch off the power and maybe it takes around less then 10 for the gas in the tube to disperse. That's how my JBJ solenoid work
by 'insensitive', i presume that you are refering to controlling the co2 bubbling rate.
it is normal with 'manual' regulator. you'll need a needle valve to effectively control co2 bubbling rate.
however, you need to be careful with your setup. the output pressure of your 'manual' regulator may not be controlled and may exceed the designed pressure of a needle valve. usually, the pressure limit is 10 bar.
to be safer, you'll need a proper regulator whose output pressure is fixed. then you can use a needle valve safely.
