weird keg issue

[newToBrew]

so
have fridge - have corny keg - gas ect.

had two kegs pretty much full - force carbed  1 - over carbed - but it worked anyway

once that was drank - I went about force carbing teh 2nd keg

this was @ 2 weeks ago - so its been at 2 bar at low temps for around 2 weeks - 10 days i'd say
and its still flat as a pancake - I know the gas is going in - coz I released teh pressue to drop it to @ .5 for serving and could hear the gas going in

I don't think its leaking as I am presuming that at 2 bar for that amount of time I would notice the gauge dropping that measures the amount in the cylinder

but a leak is the only explanantion I can think of

any thoughts ?
I'm considering transfering the beer to the keg I know works

[johnrm]

Any valves in-line that may have been shut off?
Was the Gas-in on correctly?
Did you purge the headspace in the Keg?

[Ciderhead]

You can hear the tank going when you open the valve right?
Take the hoses off is the tank holding pressure?
Use star San mister to look for leaks
What temp are you tring to pressurise
Have you tried rolling it on the floor you will get gas into you keg

Will have to put a thermometer in fridge to check

Valves are open - only one on the reg

Can hear gas goin in so I'm presuming jg con is ok

Didnt deliberately purge head space - but I guess that's beendone with the few releases I did to refill  at serving pressure

Yeah - will try the spray over weekend - kinda thought though given that there is gas to be released when opening the keg valve that even if it was seeping out somewhere there would still be enough gas inside to give it some kind of carbonation


( meant to put this in equipment not gen discussion - sorry)

I don't think its leaking as I am presuming that at 2 bar for that amount of time I would notice the gauge dropping that measures the amount in the cylinder

Since the gas is liquid that gauge is little help in working out the vol of gas used. Weight the Cylinder if you want to work out if how much gas is being used

[newToBrew]

Haven't done anything with this since really - but checked it last night and it seems lightly carbed now

I have a really stupid question - you know how some liquids don't mix and one sits on top of the other like oil and water say - the same couldn't happen with gas could it ??

Not one bit sciencey guys so feel free to laugh away here !!!

I thought maybe there was a blanketof oxygen lying on the beer and the co2 was just sitting on it - I doubt it though -guess I still need to test for leaks !!!!

God i feel really stupid now I've typed that out !!!

Firstly, there are no Stupid questions.
Secondly, now that that is cleared up, ask as many stupid questions as you like! 

[johnrm]

You are half-correct.
Some gases stratify - i.e separate into layers.
CO2 is denser (heavier) than O2, so sinks and will provide the blanket that you need to prevent oxidation.

Think of it this way...
Plants are/consume Carbon, they take CO2 hold on to the C and release the O2
If oxygen floated off, they'd be fucked.

+1

when you flush c02 into your kegs its heavier than air, ask john he poured some out of a keg onto his face and nearly fell over
the reason why after filling your keg you flush with co2 is to allow the oxygen escape out your vent and co2 sit on top of your beer and preserve it.
also under pressure it will get abbsorbed by your beer hence reason to maintain constant co2 pressure on it
Have you got the posts the right way around and stems on correct posts?

[newToBrew]

So I got it backwards ! Not so bad !!  Thanks for that  - yeah connections and posts are correct - reckon I may have a seepy leak somewhere

[johnrm]

A seepy leak? Maybe you have a leaky seep.

Use a Squirty bottle with soapy water or Sanitiser to check for leaks.
Maybe one of your conectors was not on right.

If you had gas on for 2 weeks and there was a leak, your gas would be gone I would have thought.

[newToBrew]

yeah considered tha myself - its seems lightly carbed now - it was weird though - flat as a pancake for ages, been wondering all kinds a weird things ( not the usual weird things now ) i should do a test for leaks i guess 

[Ciderhead]

N2B blast the shit out of it up to 3 or 4 bar, then you'll find your leak 

Hey you two collecting tomorrow down next Tuesday. 

[newToBrew]

Might give that a shot so !

I'm around - be in work all week on that estate - let me.know what suits

Cheers !
