Leaking C02 equipment?

[Dan2539]

If I leave my CO2 tank with its main valve shut but the line still pressurized and disconnected from a keg, is it a bad sign that the pressure drops on the secondary gauge of my tank eventually? I have an old micromatic regulator and my last fill of CO2 seemed to last a very short time. I think a leak somewhere is possible. If I hook my tank up to a keg and hold my ear to the CO2 tank I can hear the tank continuously making a very faint hiss.

Spray the connections with Starsan. If there is a leak it will bubble.

Could my symptoms be caused by the regulator more likely? Can I put starsan directly on the regulator to find leaks? I just got a new line kit. Should I open the keg diconnect and put keg lube on its internal o rings. It's brand new. I have a check valve on a wye fitting for use with my beer gun. Should this be capped when not in use? Sorry for all the questions lol.

I'd spray the regulator. There's a good chance that that is where the leak is coming from. I just got a kegging kit and my regulator, fresh out of the box, had a leak at the primary gauge connection. I found it, took apart the regulator, added some teflon tape and now it's perfectly sealed.

Use the soapy solution on the regulator and all connections, pinpoint the leak and fix it. Good luck!

Missed a set of threads on a ss to brass connection when I was tephelon taping. Taped that spot. Also put my pin lock connector under some starsan and noticed a few bubbles. Opened it up and put some keg lube on the gaskets. Problem solved, thanks for the input guys!
