I now have kegs for my homebrew. I have 3 kegs, and 1 QC with 5' hose and a picnic tap. I am wondering what I should do between pours with the line and tap? It can be a few days between pours and I am wondering if I should be disconnecting the hose and flushing it out at the end of the evening, or do I just leave it hooked up until I want a pour of a different beer then flush the line with the new beer before pouring? I use one gas line and swap it from keg to keg as well. I guess my concern is if the beer in the line will get infected just chillin in the tubing for a few days at a time repeatedly?
