CO2 Tank empty!!!!

[jrc64]

OK, went to pour a pint todat and CO2 tank is empty!!! It is a 5lb tank and had it filled 2.5 weeks ago!!

I checked all connections with soapy water when I installed. I will admit I did not check the keg seal (Big O ring), because it seemed liked it sealed very tight.

What the heck happened here????

Start with the seals on the keg and move backwards. About a year and a half ago I knew I had a small leak somewhere and went crazy trying to find it. Ended up being the pressure release valve was not completely screwed in. It was the faintest of leaks and not in a place I would have normally thought to check. Good luck.

With any tank be it Co2, propane, or any purchased gas it is good to shut the main valve off if, it is not going to be used in present time!

When I keg a beer I blast it with about 45psi to help seal the lid. I also use fresh keg lube each time. Also care seating the lid. I've noticed sometimes it can shift a little when clamping

I'd agree if you're going to be going out of town for several days. Otherwise, you ought to be familiar enough with your system and test for leaks sufficiently that you're confident that it's not going to spew CO2. Opening up the keezer to turn on the tank valve and the opening it again to close it after each tasting session should not be necessary.

+1 on comments about checking for leaks, especially around the lid and PRV. StarSan in a spray bottle works rather nicely for that. Keg lube is your friend. Use it generously. Use Teflon tape on all threaded connections.
