Just started using floating dip tubes. I'm having some issues bottling beers off the tap.
Specifically, I'm "counter pressure" filling bottles using a long hose over the faucet nipple which seals the bottle to control flow and foaming. Using some of the "we don't need no stinking beer gun" methods. Works great with a regular dip tube.
What is happening is the first bottle is filled no problem. The second bottle will often fill halfway and then nothing but CO2 and wet foam out the tap. If I'm doing a growler it happens around 1/2 filled. This only happens with kegs using a floating dip tube. My regular long dip tube kegs I can repeatedly bottle several beers or growlers no issues.
My theory....the floating dip tube pick up is just below the surface. When you tap a beer the head space pressure is reduced, causing a brief layer of foam to develop inside the keg. This foam lifts the float which lifts the pick up just enough to rise above the liquid level and into the foam layer. If I leave it alone for a bit, I can resume tapping as normal. My guess is the foam dissipates and the float drops the pick up point below the surface again.
