Too much head...

So I have been kegging for a couple years now and I still can't seem to get it right. Originally I had my tubing too short, 7'. So I coupled two 7' foot sections together with a barb fitting. It flows well for half a pour and then starts to foam. I'm assuming it's because of the barb in the middle but before I replace it, was hoping to get your thoughts.

I also have problems with my regulator drifting up over time. I'll set it for 12 psig; when I check it in a couple of months it's 20psig. I actually changed my first regulator because it did this and now I find the replace does the same thing. Do they all do this or am i just buying crappy regulators.

 

are you changing where you store your tank over those couple months? I'm wondering if it's related to a temperature change.

 

I don't remember the brand, but I got it through Northern Brewer; it was pretty standard, not a high end brand.

The tank is in the kegorator and should be at a pretty constant temperature.

 

If you are getting too much head just get married and the head will slowly disappear over time

 

I have a cheap regulator that drifts, and 3 TapRites that don't. You get what you pay for.
