Problem: Based on the research I have done I am having CO2 bubbles break in my beer lines that float up from the coupler and also form a pocket of bubbles behind the faucet. As a result my first & sometimes second pour is at least 4 inches of foam. I have changed every washer, gasket, etc. I have adjusted the pressure and temperature from a low of 5 lbs to a high of 14lbs.

It appears that I can stop some of the bubbles from forming in the line when I ramp the pressure up to 15 lbs or so, which minimizes my head to less than 2 inches and keep the temp at 33-34 degrees.

I actually get the most bubble build up in my lines when I have the temp set at 38 and the pressure at 10 lbs.

What is causing these bubbles? Is it a pressure/temp issue?

The odd thing is that it never did this with Pony Kegs on full size kegs.

thanks
