Fruit flies had colonized the waterlocks on carboys #5 and #7, as well as the un-named 3 gal. carboy of mead that had been slowly mellowing its way toward potability. I had to pour all 13 gallons of alcoholic goodness down the !@#$!@#$ sink — one of them smelled a bit strongly of vinegar, and while the others didn’t, the notion of emptying out a bunch of half-drowned flies from the waterlocks and reattaching them really didn’t appeal. I declared them violated, and am just glad that the majority of carboys (the remaining ones, as it happens) are all feeding blow-by tubes into a large mason jar of water instead of waterlocks. Perhaps someday soon I’ll bottle them.
