Hey HBT!
Yes, this is another CO2 leak thread. I've been chasing CO2 leaks after loosing a 10# bottle over a ~3 week time-frame while hooked up to only two 5G kegs. Yes, I isolated that leak to the gas disconnects that just needed a bit more tightening. EDIT: Yes, my CO2 bottle is inside my keezer!
One thing I noticed was a steady decrease in humidity over those few weeks; down from ~80% to the upper 30% range. At the time I thought my EVA Dry 500 was really doing a fantastic job. But after replacing the bottle and fixing the leak, the humidity level stayed in the ~70'ish range and wouldn't drop lower, not even after swapping one EVA500 out for another that was freshly recharged.
Move on to today, I've added 3 more kegs and started carbing these too. All new additions; gas lines, disconnects etc.. I'm once again noticing a decrease in humidity and have started trying to do isolated leak-down tests to rule-out or find a potential leak. (leak-down test is closing off sections of the air distribution, closing the CO2 tank valve and watching for pressure drop over periods of time.)
This is hard since these beers should be absorbing CO2 now and I assume that would result in slow pressure drop.
Now on to my question, has anyone else observed that a CO2 leak would cause a decrease in humidity? Or maybe cause a hygrometer to report things this way? If confirmed, this could be another tool for determining that you have a problem as opposed to buying a somewhat expensive CO2 detector like this one from Inkbird.
