I hadn't used this kegerator in a couple of years (the fridge has been plugged in, but I've had nothing attached). I bought a brand new 3/16" hose and connected it and now I get about 50% foam coming out on a new keg.
When I used to use this, everything was fine before. I'm not sure what is different (other than the new line).
I have about 5' of hose that rises 2' in my fridge (maybe a foot). I've used the calculation found here with this number and came up with that I should be having about 16psi. This seems rather high.
At any rate, I've tried lower PSI and the higher PSI; all generate foam. I've noticed that after a pour, I get bubbles in the line right out of the keg immediately. What could I be doing wrong?
The only thing I could think of is the plastic retainer is a bit mangled; I've ordered a new one but it hasn't came up yet.
The fridge stays at about 40F. Any help would be greatly appreciated.
