Beer line length

[psychodad]

I have pockets of air that accululate in my beer line over night. I am sure that this is a large part of my foaming problem. Also from what I gather twists and whatnot in the beer line contribute to foamy draws. What would be wrong with cutting my beer line where it enters the tower so that it is just long enough to reach the keg coupler with a bit of slack? Would this help or hurt anything?

The reason you have a pocket of gas accumulating is either due to a temperature fluctuation (hot spot) or your pressure is not high enough and the gas in solution is breaking out.

Beer line length and diameter is utilized in a draft system to control the flow rate of the beer as it comes out of the faucet. If you alter this, you will alter the flow speed. Always concentrate on balancing the pressure to the keg first with the correct PSIG.


Target 38 degrees F beer temperature. If you would reply with your beer type and elevation we can indicate what your PSIG should be. The length of the 3/16" line will be based on this PSIG at the keg.
