I'm completely new to kegging and I'm experiencing some growing pains. I foolishly over filled my keg and set it to 30psi for two days. I want to purge and set it to 12psi but beer sprays out the in post when I depress it (it has no relief valve). What happens if I don't purge? Should I try to pour beer out of the picnic tap to lower the volume?

Help!

i would think that if you turn down the regulator the beer will absorb the excess pressure without over carbing it so you don't have to waste beer.

^ If the gas line had a functional anti-backflow device (aka "check valve", which is not the same thing - but may be contained within - a shut-off valve) you could likely get away with lowering the CO2 pressure. Without a check-valve, however, you immediately risk having beer flow back up the gas line into the low-pressure side of the regulator body. Not good...

Cheers!

If beer spurts out of the in post when you press it, then I wouldn't turn down the regulator pressure. I've had beer backflow into the gas lines by doing that. Personally, I'd disconnect the gas and just pour foamy beers for a couple of days. Once the carb level gets close to what you want, set the regulator to serving pressure and you'll be good to go.

what if you take off the gas line and slowly pressed the ball valve?

I have a taprite regulator that included a check valve so the regulator should be fine. I'll shut the gas off tonight and see if there's beer in the co2 line.

After setting the reg to 12psi I poured a bit of beer from the tap to relieve some pressure, and sample some beer. The pour was surprisingly smooth for all the pressure in the keg.

The beer shower was actually quite fast.
