Okay, at some point, on my first tank of CO2 I was getting a buzzing noise, very faint from my regulator. It appeared to be coming from the tank pressure gauge area and I tightened down that gauge a little bit and it went away. Not too long after that I finally ran out of gas on that tank. I’d gotten roughly 7-8 kegs out of that tank. So, I didn’t suspect any further issue. I hooked up another tank a while back and looked at the pressure gauge a few weeks later and it is almost empty, yes I do understand how the tank pressure gauge works and how temperature has an effect on it. So, I’m assuming a leak somewhere.
If I close down all the valves leading out to the lines and pressurize the regulator section, with no pressure set on the regulators, and then turn off the CO2 tank, the tank gauge remains at the tank pressure, based on the remaining pressure in the regulator area. When I come back hours later the gauge has dropped to zero. Wouldn’t this indicate that there is a leak somewhere up in the regulator head area? I just want to make sure I’m not misunderstanding something here, but it would seem that if I pressurize that area and seal it off the gauge shouldn’t move unless I purge the regulators.
Don't worry, I've shut everything down and will be checking the line connections and QDs this weekend, but started with the regulator assembly because of the previous noise I heard coming from it.
Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience. - C. S. Lewis, English essayist & juvenile novelist (1898 - 1963)
