Will slightly increasing the diameter of my dispensing hose increase or decrease the head? How about shortening or lengthening the hose?
I have a pressure relief valve guage, and the headspace pressure in my cornies and lagers is never over about 10psi for the bitters and pales and maybe 12 for the lagers. I push this at anywhere from 6 to 10 psi per the regulator. The tap is a cheap plastic "picnic" style tap.
Nevertheless, I get more head than I want, maybe 2 to 2 1/2 inches on the first pint of the night, maybe 1 1/2 to 2 thereafter.
This is with, I believe, 3/16 in ID tubing, maybe 5 feet of it, all inside my garage sale chest freezer at 45 fahrenheit (I know it's on the cold side but it's kind of a compromise between the ales which would be better at 50 and the lager which seems best at around 40). Also the tastes of others and the fact that a sitting beer warms up, but doesn't get any colder....
I recall tubing diameter and length as variables you can play with to affect head, just can't remember which direction you move them in to get a reduction...
