Commercial keg foaming

Just hooked up a 1/6 barrel of Sierra Nevada Torpedo, and I'm noticing a constant stream of bubbles rising up from the coupler (visible in picture). It's currently at 14psi. I did purge the keg before pressurizing with my line.

Am I just underpressurizing it?

 

I found when I had commercial kegs on tap I was running closer to 4psi. I had no problems with mine. I dont remember it going above 10 at any point. Could just be me though.

 

Just a guess, but at 14 psi. you're actually carbing it more. Turn it down to ~6 - 9 and you should notice the bubbles stop.

 

Thanks for the suggestions. I may have jumped the gun with my post, as the stream seems to have abated.

14psi is about right given the length of line I'm using. Based on the height of my system, my other taps all have 12' of beer line.

 

Perhaps the keg was a bit warm and just needed time to chill...

Cheers!
