Default Problem/Foam Keg

So I have a ball valve corny keg with a 5lb co2 tank connected.
It has a 5 foot line attached to a picnic tap.

Every time I go to pour a beer all I get is a cup full of foam, except when I turn off the CO2, bleed out the valve, detach my tap, and attach a friends foot disconnect to picnic tap while pouring at a downword angle (if I try anything lower then 10psi it will not come out of the 5 foot line and at 10 it foams like a beast).


This has happened for both of the beers I have kegged so far. The first one I rolled at a psi of 15 for about 6 or 7 minutes then left it at 15 for a solid week. The second one I rolled for a solid 10 minutes at 30 psi, left it at 30 for an hour, then bled out the pressure and put it at serving pressure.


The keg is very clean, I am fully opening the tap, I bleed out the pressure before putting it at serving, the keg is very cold, there is no residue in the line, all the bolts are very tight, the lines are in the fridge with my keg.
My keg seems to leak until I turn on the gas and get the lid at the perfect angle (may take like 10 tries at a time)...

I have had several friends that also brew come take a look at it and they have no clue how to help.
What is going on? Please help me solve this before I go insane.
Thanks in advance

A 5 foot line will never cut it in my opinion. I have an 8' line on my kegs, all of them at about 2.4 volumes, and I never have a problem with foaming. Get rid of the "rolling" method. Just set your regulator to about 12-14psi and let it sit for two weeks. It will foam for the first couple beers, but it should be fine after that if you're using it often enough. If not, you may need to put it down to 5psi while serving.

As long as your system is balanced, you shouldn't have these issues. What kind of kegerator are you using? Have you accounted for the height of your tap?

I am using a chest freezer with a temp setter, and a line with picnic tap, open and close the freezer to actually be able to pour it.

See I thought hte same thing, but down to 5psi the beer wont even POUR out of a 5 foot never mind an 8 foot...

So nothing comes out below 10PSI and it foams like mad over 10PSI? I would suspect a clog somewhere along the line.

Have you tried a different disconnect/line/tap? You can pick up another setup for about $14. http://www.austinhomebrew.com/produc...oducts_id=1271

Also, what was your process for carbing? EDIT: I reread and saw that you posted your method. The boost and shake method usually gives me all foam if I try to pull a pint in the first day or so.

For your next keg, try not rolling/shaking/messing with it. If the keg is "very cold" (what temperature is that?) set it for 10 psi. Leave it alone, without changing the pressure or shaking it at all.

My fridge is at 40 degrees and 12 psi works well. After 10 days, pour a beer and see how it is. You shouldn't have any foam or anything like that.

It does sound like you've got something "pinching" off in your "out" line, though. Can you buy a new disconnect, and double check the poppit on the out post? It sounds like you've got something stuck in the poppit. I'd pull off the post (depressurize the the keg first!), and clean it well and inspect the rubber oring on the poppit. I'd also stick a new disconnect on it, too. Sounds like maybe an o-ring is missing on the black quick disconnect.

fwiw, someone started a similar thread a couple/few weeks ago that eventually turned out to be due to the picnic tap not actually opening fully...

Cheers!

Before you try buying a new poppit, try putting your liquid out connector on your gas line. Then force CO2 in, through the liquid out port. If you try to connect your gas connect to the liquid out, it will get stuck, so you need to switch them. I usually crank the co2 until I hear bubbling. If you hear bubbling, then you probably don't have a clog.

What is a "foot disconnect"? Does this method still use all your equipment with the addition of your friends?

What others have said about a clog does seem to make sense, but how does the foot disconnect counteract a clog?
