CO2Art Regulator, solenoid doesn't completely shut
I have been dealing with the same issue with the CO2art regulator for a long while. The solenoid does not stop gas flow once it turns off. Rather, a bubble everyone few seconds continues. Sometimes many hours later the flow may stop but other times it flows rather fast. I contacted them and was told to take apart the solenoid and clean it. I've done so multiple times but there is never any dirt and nor does it fix the issues. So after that vent, any ideas on what else may fix it? Also, how long should it take for gas flow to stop, a few minutes, a few hours? If it's a few hours then maybe this is normal? Thank you!
