On Tuesday, my keg ran empty and I washed and sanitized it and racked my next batch into it. Purged and bumped up the pressure to 30 psi and stuck the keg in the fridge. Ever since Tuesday, there has been a slow leak of liquid from the gas post that will begin to run down the side of the keg after about a day (so pretty slow).

Would liquid leak from the post if some of the brew had gotten into the gas line? I really don't know what else it could be since there's CO2 to keep the liquid away from that post, right?

Thanks for the help!

P.S. The previous batch kept pressure with no leaks for about a month and I didn't do any adjustments on the posts between the batches.

EDIT: Never mind about the post. It looks like the liquid is seeping out from between the rubber 'sheath' and the keg top. The lid itself is bone dry. Is there a seal under the rubber? I was under the impression that the keg was a closed system minus the posts, the lid, and the relief valve.

No. It was probably about 3.8 gallons worth of liquid in the 5 gallon carboy.

You might have a CO2 leak. A small amount of moisture can come out with the CO2, especially under 30 psi. Try tightening the post.

I normally find that if you have o-rings in good repair, you dont need the post to be much more past snug to get a good seal.
I sometimes get a poppit that doesn't seat quite perfectly. A little poke with something will normally get it reseated squarely.

Does the poppit have a nice, non-jacked up o-ring/seal? You may need to replace the thing, and if so, I'd recommend the universal poppits. They rock!

Here's a picture of where the liquid seems to be coming from. Right near the 'IN' text between the rubber and the metal.

From the pic I would expect the leak is under the gas post. Maybe the o-ring under the post got nicked? The only other possibility is you've somehow developed a split, but that's an unusual spot for that to happen - there's no seam near the posts...

Cheers!

Double check the dip tube o-ring for any nicks or imperfections, as day trippr suggests.
You may also have to do some investigation into whether or not you have a leaky weld at the base of the post. It's easily fixed with JBWeld, just hard to troubleshoot since you have to lift the rubber on top.

I still don't get how liquid is getting there, even if there's a leak. Where is the liquid coming from?

Silly question, but that's the side that you have the short diptube on, right?
