Aquatek Mini Regulator leaks nearly all CO2 after 3 weeks consistently.

Hello,

So I recently picked up this regulator with an Empire 20oz tank. I've been having an issue where after about 3 weeks of running the tank suddenly starts losing pressure. I refilled it, tightened everything and everything seemed fine. 3 weeks or so later, the same thing happened. I tried spreading soapy water over everything but I don't see any bubbling.

Anyone know what causes this? It's only 3 months old...

Replace the O-ring on the Co2 tank. I can't say for certain that this is the problem, but I had a deformed O-ring on a tank that leaked. Replacing the o-ring solved the issue for me.
