I have a side-by-side fridge modified to serve on the left and ferment on the right. The position of the taps (perlick forward-sealing) and kegs means that one of the kegs is higher than the taps and two are below the tap height. I have had foaming problems off-and-on since I setup my rig. I have experimented with different lengths of hose as well as temperatures and pressure settings.
I noticed something today - with my coil of 3/16 hose in there, there are "dead zones" in the line filled with air or foam. When I pour a beer, I think the dead zones are getting spit out in the form of foam. I am surprised that the quick disconnect doesn't act as a check valve, preventing beer from flowing backward after pouring. But sure enough, if I watch the lines after I turn off the tap, I see bubbles and air flowing backward.
So can I just add a 3/16" check valve in line right after the quick disconnect fitting? I want all the beer drawn past the pinlock fitting to stay in the line until the next pour.
