My guest tap is foaming my beer. It is a snake tap. The beer line leaks beer back into the keg maybe. The line gets air I it. Each beer is foamy, if your pour two, second is fine, but when when you wait it foams. You can see the air pockets in the beer line between pours. I switched the line to another tap, so it isn't the faucet. Where's the issue? In the tap itself? In a gasket? If so, where? Basically, it's allowing beer to drain from the beer line, but it must be back into the keg I guess, it isn't pooling in the keezer, isn't leaking outside, beer is carbonated. Thoughts?

Line is getting too warm? Shorten or add glycol system."I don't have TP, but I do have ammo."
-Some guy in Ohio -
The line does not leave the keezer, it is 9' long. It is the very small, semi rigid line. Same as all other lines that come from my ball locks, but this one just started having problems with this keg.

Any hole would be a leak out, not in as it's under pressure, unless its inside the keg...."I don't have TP, but I do have ammo."
-Some guy in Ohio -
A temperature change in the line is the obvious cause of co2 coming out of solution in the line. If its the same elevation and line type and length as the rest then you can probably rule this one out.
Switch your kegs around so you put a different keg on this line. I'll bet the problem follows the keg. The dip tube may have a pin hole in it somewhere letting co2 into the line. Or a bad inner gasket if it is that type. I have a couple that have an o-ring that seals diptube from the headspace if that makes since. I won't leak out but it sure will cause foamy pours."On it.

It's freaking highlife, just chug it till it's gone."I don't have TP, but I do have ammo."

Since you said its all the same temp then the answer is limited to this: the keg is carbed at a higher pressure (vol co2) than what you are keeping it at. If you lower the temp, the issue could go away, if you raise the serving pressure the issue may go away.
What's happening is the co2 is going ou of solution while in the line, creating gas bubbles. You need to stop that from happening by balancing the pressure of the gas and solution. The two options above are not the only two approaches, alternately you could lower the vols of co2 in your beer by taking it off the gas and bleeding a little head pressure until it stabilizes at the same head pressure as your serving line.The only thing between me and a train wreck is blind luck..... - Kenny -
It's a snake keg so I don't know what's going on inside it. It is Sēance from Magic Hat. If its a keg problem, I can't do anything about it I guess.

I am holding my serving pressure at 11 psi. I've had this keg tapped for 2 weeks, problem has been there the whole time I think. So you think I need to crank it up? -

If lake is right, which is likely, then the problem will also go away as the carbonation reduces due to low pressure. How long has this been going on?"I don't have TP, but I do have ammo."

Two weeks, maybe as long as its been tapped. I don't recall -

In a well conditioned beer it could take months for it to slowly equilibriate on its own. It would resolve itself pretty quick as you got down below 1/4 full though.The only thing between me and a train wreck is blind luck..... - Kenny -

Cranking it up a couple psi will likely cure the bubbles in the line, but it could cause foaming due to an aggressive pour.
Its a balance. One thing you can do to help, is to make sure the line doesn't go up and down as it goes from the keg to the tap. Those whoop-d-dos with encourage foaming too.
I'd probably set the regulator at 13psi and organize the line so it is always going either uphill or downhillThe only thing between me and a train wreck is blind luck..... - Kenny -

I tried to straighten the lines, but they are rigid, so you can only straighten so much. I turned up to 13 psi. I'll see what happens. -

Didn't help. I turned it back down to 11 after two days. High spots on the curve hold air. It is either a bad keg or my tap has some seals going bad. I've used this for a couple years with many kegs and it has never happened. I'll probably wait until I swap this keg and see if the next one is better. If no better, I'll start replacing seals on the tap. I need a new tap, so I might just replace that

Full circle... Quicker than normal, odd, no one got sidetracked."I don't have TP, but I do have ammo."
-Some guy in Ohio -
What I keep hanging up on is that it gets better after the first pour if you have consecutive pours? That nearly has to be pressure, line temp, or line elevation related. The only leak that could cause this and not a puddle would be a leak from the diptube back into the keg. But that would continue with each pour once the liquid level dropped below that hole."On it.

If it was a dip tube leak it would have to be a very small one. I'm still thinking it could be an over carbed situation."I don't have TP, but I do have ammo."

Most likely.

The carb has been the same for the past few kegs. All lines are the same, temp the same, etc. only difference is the keg itself. I had it turned up to 13 psi at 33F, I can't imagine turning up the co2 higher than that. Either a bad keg or something went wrong with the tap. Not sure what could go wrong with the tap to cause this.

Have some empty cornies?"I don't have TP, but I do have ammo."
-Some guy in Ohio -
Yes. Are suggesting I empty this into one? It's a sanke keg, so I'd have to rig something up to transfer and honestly, I'm not that motivated.

I suppose if some debris could be hung up in the tap or faucet? Maybe? Does it pour slow?

I don't think even that would cause that problem."I don't have TP, but I do have ammo."

Yeah. I think you're right. I don't even know. Switch some stuff around and try that.
Or, just drink the keg. Hit it. Hit it hard."On it. I hate software." ~Cpt Snarklepants -
The only things I can reasonaby attribute to this are:
Over carbed beer
Loops/high spots in line
Variable temps btween line and keg
Dirty or infected lineThe only thing between me and a train wreck is blind luck..... - Kenny -

I agree with 1 and 4. 2 and 3 I think have been reasonably ruled out. Reasonably."On it. I hate software." ~Cpt Snarklepants -

could be. seem unlikely in a commercial sanke style keg, since the spear and down tube (no dip tube, dip tubes are in cornies) is made of a fairly thick walled stainless steel tubing.The only thing between me and a train wreck is blind luck..... - Kenny -

I suggested this early on when I thought it was a cornie. But even with this scenario it should be happening with every pour.

Well, keg is blown. I'll replace this coming week and see if we repeat this discussion. For the sake of lost beer, I hope it's the keg.

Doing it still. I tried a new tap, butterfly sanke tap. Tapped and poured a beer. After I shut off faucet, bubbles begin to arise from the tap at the keg into the line. Why the hell is this happening?
