Problems with m3 CO2 regulator/solenoid?

[ed99]

Folks,

I recently bought a CO2 reactor that came with a m3 regulator/solenoid. I was unable to get more than 24 hours out of the first one before the CO2 flow would stop. It would restart only when I unplugged and then replugged in the solenoid valve. I exchanged it yesterday and now after 12 hours I have had the same problem with the new one.

Has anybody else had this problem? These valves are brand new and pretty simple- is there any explanation for the problem besides a defect? The CO2 is food grade and water has never got near the regulator.

Thanks,

Ed
