Corni Keg leaks Co2

[Philip]

My two questions are:
Should the corni keg lose 7psi of gas (straight Co2 i.e. Not mixed Co2) over 24 hour period?

Can I transfer the beer from the full corni keg to the nearly empty corni, bearing in mind that the beer is carbonated?

One of the corni kegs (the one that is almost full) is losing about 7psi over a 24-hour period. I've tried pouring water over the top of the corni but I cannot see any leaks or hear any leaks. I've phoned the shop that has just sold it to me and he said,
"The Co2 is being absorbed by the beer because you are storing it at 13c"

It's a Sheraton Bitter.

I think it depends on when you filled the keg. If only recently, it's true the beer will absorb the Co2 and you'll need to keep topping it up for a while.

Others will come back with more info I'm sure but, it's nothing to worry about in the meantime.

If the amount of CO2 in the beer has reached equilibrium with the CO2 in the headspace then no it shouldn't. However it is quite possible for the beer to absorb most of the CO2 from the tiny headspace that's present in a full keg of beer. Additionally Corni's don't seal very well at low PSI so maybe the beer absorbed some, the pressure dropped, then the keg started leaking.

Can I transfer the beer from the full corni keg to the nearly empty corni, bearing in mind that the beer is carbonated?

Yes. You need two beer out disconnects and you'll need to push the beer across using either CO2 or gravity (after a push with CO2).

I've tried pouring water over the top of the corni but I cannot see any leaks or hear any leaks.

There's any number of places it can leak. The lid O-ring is most likely followed by the gas in poppet valve.

I transfered the beer into the corni 4 days ago.

I've topped it up with Co2 about 4 times. On one occassion I filled it to 20psi. but normally I fill it to 15 psi.

I didn't think about the corni being full and only a little head space which means very little Co2 going into the corni, maybe I'm panicking to early!

steve_flack, Could you explain in detail about the two beer out disconnects to transfer the beer between corni kegs.

Thanx for the replys.

[steve_flack]

It's easy really. Just join two black disconnects by a bit of tubing and put them on the kegs. You'll need to be able to vent the receiving keg by either loosening the lid or by attaching a grey disconnect. A certain amount may flow on its own but eventually it will stop. I'd use CO2 to push from one to the other but unless you have a pub gas cylinder it is a bit wasteful. You could try putting the receiver below the sending keg and vent the sending and try siphoning.

[Philip]

Does the black disconnect connect to the "out" on the receiving corni?

Thanx for the reply.

Just a little tip on checking for leaks. Spray soapy water on the corny, that way it will bubble up no matter how small the leak.

Also, corny lids don't always fit right. I put a small piece of cardboard under each arm when closing to get a little more pressure.
