I have been draining CO2 tanks like it's going out of fashion. I've discovered three leaks
1: one of my regulator bodies (can hear it, but no bubbles from soapy water)
2: the straight piece from tank to primary regulator body. Think i fixed it with silicone and tried tightening it.
3: my carbing line wasn't clamped so that was leaking a bit.
How can I fix a leaky regulator?
I'm using the Norgren regulators here
I took it apart, basically it's a membrane with a spring and screw nut thing for adjusting pressure. Leaky membrane perhaps?
Other option is to scrap this for a manifold. I keep all my pressures on 10-12 anyways for all beers. I do however carb off my primary. So I'd need at least one secondary to regulate that pressure.
