This is my second time with this problem. First time was with the Hef and the second time was with a rye IPA.

First Half of the keg pours great. As it gets empty the foam gets worse and worse. I have tried purging the Co2 out of the keg, adjusting serving pressures anywhere from 3 to 10.

Taps are coming directly out of the door of the fridge, 10 foot lines of 3/16 all in the door and staying cold.

Puzzled.

another thing too...
how long are your lines?
how was the keg carbonated?
i'm (probably as the other guy is as well) thikning that your beer wasn't fully carbonated when you served and it just started overcarbing as it was sitting on CO2 for longer and longer
 
Carbed at 35psi for 24 hrs. The. Down to 15 for 3-4 days. At 36 deg.

Then I purge and reset regulator to 4 lbs serving pressure.

Not sure on the same keg. 1 in 3 chances.

Can't fill a growler cause 30 min later it's all flat.

Also, when looking at the line, while pouring, what should I see?
 
If you are wanting to force carb, cold crash to the serving temp, either in the keg or pre-filling the keg. Using one of the many carbing charts, set your CO2 pressure to the desired pressure of your serving temps. Shake the piss out of the keg for 5-10 minutes. Place back in kegerator/keezer and let it sit for a couple of days. Keep the pressure the same as you started all the way through the use of the keg.

Still have issues? There might be a huge temp swing between the bottom and top of your cooling vessel.
 
not sure how accurate I am on this but it seems I have noticed if I have less head space in my keg it takes longer to carb. I usually don't shake carb my kegs so not sure if this really matters in your case, but it may help you.
 
I am having the same problem with my hefe this time around. I have brewed other beer and haven't had this problem. I think it is because I tried to force it too quickly or something. I cold crash for a day and set the co2 to 25-30psi and roll it gently for 10 minutes a day for 2 days. Then purge and bring the psi to 10 lbs. My keg was completely full this time and I don't think that I gave it the time it needed. I get a lot of foam on the first beer and if I don't pour another right away, within 10 minutes it does the same thing. I think it has to do with not being properly carbed from the beginning. I would love to hear other thoughts on this.

Cheers!!
 
Can someone post a video of the line coming out of the keg? I wanna see if it looks like mine. Mine is not solid beer.

Could it be the o ring on the pick up tube? Air and beer getting forced the ball lock?

No. It sounds like the beer was carbed to a higher pressure than it's currently being served at, and co2 is coming out of solution. It is very easily fixed, by keeping the pressure the same all of the time instead of over carbing and then turning it down. Keeping it at 9-10 psi all the time would fix it
 
... adjusting serving pressures anywhere from 3 to 10. .....

Don't adjust "serving pressure." Your serving pressure should be your carb pressure- otherwise you unbalance the system and get lots of foam.- Use the carb chart, set it to your desired Volume of CO2, and leave it!
 
Carbed at 35psi for 24 hrs. The. Down to 15 for 3-4 days. At 36 deg.

Then I purge and reset regulator to 4 lbs serving pressure.

This is undoubtedly your problem. Your beer starts out carbed properly but then you lower the pressure so now it can loose carbonation and foam in the lines. I set my beers at 12-13 PSI at 38 degrees and leave them, 10-12ft lines, perfect pours every time.

Your serving pressure is way too low for the kind of carb level you're putting into the beer with that method.

Yep.

There are only two causes of foam/gas pockets in the beer line, and in your case it's pretty obvious which one it is. Your serving pressure needs to match the equilibrium pressure of the carbonation level. If the serving pressure is too low, CO2 will want to escape, and as it sits it will form pockets of gas in the lines, resulting in foamy pours.

A bad o-ring on the liquid side dip-tube can also create pockets of gas in the line and foamy pours, but they will be present in the lines at the same quantity all of the time. If you pour a couple of beers and the lines are full of solid beer for a minute before gas pockets start to form again, then your serving pressure is too low. If the pockets of gas never go away, even for a moment, then it's a bad seal at the liquid dip-tube o-ring.
