One of my kegs isn't giving me it's bounty! I hooked it up to 2 different lines (both worked on my other keg). Removed and cleaned the diptube. Not sure what to do from here. It worked for when I ran sanitizing solution through it. Any ideas
 
Is the poppit clogged? Is the keg getting gas pressure? Maybe it has a leaky lid or the gas connector isnt engaging it's poppit correctly? Kegs are very simple technology, gas goes in, beer comes out. There's only a few things that could be wrong.
 
I did some googling before i asked. So here's the list.

Gas is going in, i can turn it off, purge the keg, and turn it back on and hear the woosh of gas. Also when i purge the keg when gas is on, there is constant release.

I can depress the out poppet valve and get a lovely beer shower (Not too terrible...)

I disassembled, blew air through, rinsed with hot water, sanitized then reassembled the out valve/dip tube.

I tried multiple out lines, neither of which worked, however they worked on my other keg. The irony of this is that the new keg is the one that does not work and my used one works awesome.

The keg worked fine when i had star-san mix in it prior to filling it with beer.

Its a hefe, so maybe (really strong maybe) sediment has formed at the bottom of the keg and is clogging the tube?

If i wait a few minutes and try i get about 1 to 2 seconds of low flow from the line before it stops and gurgles a little bit.


Maybe I should try to switch the poppits from the in and out lines
 
Thats weird. Maybe the poppit isn't getting pushed down enough by the pin in the connector, are you sure the connector is seated properly? Maybe a bad diptube o-ring is letting air in as you try to serve. Not sure what else it could be. I'd try fresh o-rings on everything with keg lube, make sure the ball lock connectors are assembled tightly and firmly seated.
 
Try changing the quick connect on your tank and push CO2 through the beer out side in attempt to clear the clogged line.
If you don't hear bubbles, you have a valve stuck closed.

Also, FYI
Ball lock posts are different. The gas in post should have some dash marks on it. Black QDs fit the "beer out" posts and the Grey QDs fit the "gas in" posts.
When you reassembled the keg maybe you put these on backwards?
I made this mistake when I first got my kegging system, I thought that they were all the same and the QD colors were just to help for identification.
 
Switch your disconnects and send a few shots of C02 through the out valve - if the dip tube is clogged, that could take care of it (and ensure that the poppit is working properly). If that doesn't work, you've really rounded down the potential number of problems.
 
is it possible the beer line to the tap or the tap is clogged? Blast some CO2 through the dip tube.
 
I had a batch that I dry hopped with whole leaf. After a series of frustrating tests, I finally transferred into a 2nd keg and pulled the whole keg apart. Turned out that a single hop leaf was blocking the dip tube about 2" from the bottom.

One other thought is the faucet. Have you hooked up a 2nd keg to that faucet to ensure that the line and faucet are clear?
 
Alright i just tried switching the C02 line to the "out" port and pumping some gas through (I heard bubbles). Still no avail. I swapped all 3 C02 lines, and all 3 taps (One keg has sanitizing solution in it). Both of my 2 handle style kegs work great (both used/refurbished) the single handle/new keg still doesn't work.

At this point i guess my only option is to purge and transfer the beer to the other functional keg; then proceed with complete dis-assembly and whatnot.

Just very odd, since RIGHT before i filled it i tested it.
 
You dont really need to transfer the beer out to reassemble the keg. It should only take a few mins to take the posts off, clean, lube, and reassemble.

Well i already did that with the "out" port. Didn't mess with the "in" since it seems to be working ok. Maybe i can just completely switch the posts from other kegs and see how that works.

Have you swapped the black beer quick disconnect? If you depress the poppet and get a beer shower :)rockin:) then the keg seems fine.

Beer shower is in full effect, 3 different liquid out disconnects all don't work (On this one keg) 2 of them worked prior to having beer in it. I just put the third in service to test this stuff. At least i can get my hefe from the other keg while i try to figure this crap out.

What PSI do you have the CO2 regulator on that's connected to the keg in question?

That was my next suggestion... if that doesn't work, and you've tried different liquid disconnects... maybe you're losing C02 through the lid?

All three kegs are running off a manifold connected to a single reg, running at 15 psi.


I ended up transferring the beer to the other working keg. After transfer it works fine.

I washed out the old keg, cleaned the dip tube and poppit valves. Still not working, gunna bring it back to the store i bought it from (it was my first keg, and i just started this stuff) and see what they can/will do. I'm so very confused. I consider myself semi-handy, and am an avid googler to solve problems before i ask on forums, but this has me stumped.

At any rate, the hefeweizen seems to be no worse for the wear, and is ultra cloudy. So cloudy i thought something was wrong at first (I drank the first pint and pulled another, but both were the same) Very tasty!
 
Are you sure you dont have the posts reversed? Gas post on the liquid diptube and vice versa? Maybe the poppits engage at a different depth and the liquid connect isnt enough to push it down on the gas post.

I don't think this is the problem. The gas post has notches, liquid doesn't. i dis-assembled after the transfer and the gas post is about 2 inches long, the dip tube is the appropriate length. I swapped the poppets between the posts. (I guess the only thing i didn't do was physically swap the posts and the dip tube.)

Double post, but i did properly seat the lid (Tested with some soapy water). I re-seated the lid several times int he course of this crap and never heard nor saw any signs of bad seal after it was seated.
 
I thought you were going to switch out the post and try a "known" working post. The post sounds defective. Take it off and compare it side by side with a working one. The profile may be off and the disconnect might be engaged too high and not depressing the poppet. You can try it with a little water in the keg to test.

I switched out the the liquid out poppet with an extra i had (they are different styles). This one let me upload a picture, but one has kind of a tri-pod a the bottom and is alot shorter, the other is wider and taller. The wider/taller one does not work.


Sooo i guess i figured out how to upload some pictures, the pink laptop is my wifes... but yeah.

Upon further review, i think the original poppet was too tall/large when it had the higher PSI applied to it. Only thing i can think of. Honestly its a mystery to me, im still bringing the whole keg back to the store for hopefully a swap or something.

I'll test it again later to see how it is working. As of now changing the poppet worked though
 
For all those interested, it was because of the bad poppet. It was a brand new keg with one of those universal poppets.

I took it back to the LHBS (homebrewheaven, great place) and they allowed me to exchange it for 2 used ones!

I would've gotten a used one in the first place, but they didn't have any at the time. All in all i'm pleased with how this all turned out. Short of having to transfer the beer, nothing bad came out of this.
