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!

Even after it shuts off mine typically slowly leaks out the remaining pressure for about an hour. I have a GLA reg tho.

But if its leaking all night then its not just the remaining pressure if that makes sense.

Most regs you can technically replace the solenoid with another one if you want. And there are many options out there too.

Same just happened with mine. Try stretching out the spring when you take the solenoid apart as it loses strength over time. It solved the issue for me and has been fine for a few days since the fix.

Move your check valve closer to your defuser / reactor.

Some times it creates a suction that pulls out some gas

The bubble counter supposedly has an integrated check valve. Should I add a second check valve within the line? I noticed that when I unscrew the bubble counter water leaks out the bottom, could this be a faulty built in check valve?

Thanks for all the answers! I'll try to stretch the spring again but did it last time to no avail.
