A few weeks ago I bought my first keg and regulator. I set it up yesterday with ~5 gallons session mead and set the pressure to 20 PSI, hoping for ~2.5 vols CO2 at room temperature (I have no means of temp control atm). I’ve noticed now that every few hours the regular has dipped to ~15 PSI and I have to turn it up again. I’ve triple checked every connection and felt no gas coming out from anything, including spraying everything down with star san and looking for bubbles.
It’s the CO2PO that comes with the Northern Brewer kegging kit. This is the kit I bought:
Is there something I might have hooked up wrong or is it possible I have a defective product? I assume the former, this is the first time I’ve ever kegged.
