Hi, I have an AquaMedic regulator and solenoid and yesterday I noticed when the timer is off or when I unplug the solenoid , the CO2 can't be shut entirely. the bbm becomes smaller but I still can see bubbles come through bubble counter. How can I fix it? Thx.

I feel confused. I just shut off the main valve of CO2 cylinder. but when I turn on needle valve, I see the number of bubbles increases. How does this happen? there should be no CO2 out when the main valve is shut.
