How to purge full keg?

[HiGravShawn]

I'm a first time kegger and not all my equip is in yet. I have keg I really need to fill today. I have dis/connects and a hand charger and want to purge the air out of it before letting it condition with sugar. Can I hook up the hand charger and push some C02 and then remove the disconnect and press down the gas valve to purge without spraying beer everywhere?

The preferred method is to use the pressure relief valve built into the lid. Although your method will work there is a possibility that the poppit wont reseat correctly.

Hmmm, didn't know it had one. I'll have to look harder when I get home. Is this something built into all cornies or something attached?

Not all corny lids have a pressure dump.

Yeah after a quick google I don't think I have one on my keg. I'll just have to try to be gentle with the poppit. Or bite the bullet and wait, but if I don't clear a carboy before tomorrow I have to push back a new batch two weeks

You shouldn't have to worry about beer spewing from the post as long as the gas dip tube isn't below to to the level of the beer.

I've never seen a corny lid without a pressure relief, although I have seen some that don't have a the ability to do a pull test (i.e. manually release the pressure). I would think that a pressure relief would be a requirement, but I haven't seen that many cornies that i can make a definitive statement on it.

Also, be careful purging a closed tank with one of those cartridge CO2 chargers, there's no pressure regulation on those. If you really don't have a pressure relief you could rupture your disconnect, or the keg, if you overpressure it.

and you don't want to remove that charger until the CO2 bulb is empty!
