Foam issues

[St.Frank]

ok so all of my beers have been foamy when pouring from tap. I got a party tap and put 10f of line on it to try that. I have bumped co2 to 17 foam dropped it to 10 foam. I am so lost. Please help. I went to picnic tap b/c I don’t have a fan for tower. So I tried to delete that issue

What was your carbonation process? (If you are over carbed, 10 ft might not be enough)
Is the 10 ft of line in the refrig with the keg? (Warm lines cause CO2 breakout and foaming)
Is the ID of the line greater than 3/16"? (Larger diameter lines don't offer sufficient flow resistance)
Have you tried replacing the "O" ring on the beer out dip tube? (Bad "O" ring can let CO2 leak into beer stream)

Brew on

The line is 3/16. And is inside the kegerator. My process was put it keg and let it sit at 14 psi for like 3 weeks. Then after pouring a couple of foams I turned it down to 10. This keg is new and has only had 3 beers in it so I wouldn’t of thought the o rings where bad. Just thinking. But I have 2 sets if I need to change them.

What's the fridge temp? If you're particularly cold, 14 PSI could be pretty lively carb. Especially for a 10 foot line.

In which case, dropping to 10 PSI will help, but it'll take a bit of periodic bleeding out of the tap (or PRV) to let the keg drop to equilibrium as that CO2 comes out of solution. Until then the pressure drop could cause CO2 breakout in the line and make the foaming even worse.

Of course cold will help keep it in solution as well, and warm (even just opening to pour) could also be the problem.
