I have a buddy who started homebrewing. He calls me today and tells me that he has a CO2 where he is essentially going through 5lbs every 3-4 kegs. He tells me charged kegs keep pressure once CO2 disconnected. When disconnected tank doesn’t empty.
Easy, right? Has to be gas in o-ring. Then he told me he replaced them…
On all his kegs… and they leak. He’s even tried new disconnects… and keg lube…
Now I’m at a loss. I suggested that he try new o-rings to see if there was a manufacturer error. A gas in o-ring is a gas in o-ring correct?
Any other suggestions?
