Question for anyone who has a keezer/kegerator in my situation. I would like to clean my lines with a plastic hand pump thingy, but I notice all of them for sale online have an attachment that looks like it fits on a large wingnut. The passthroughs I bought have the nipple barb built in to the pass through, so I had no need for the tail piece and wing nut. And now there's beer line clamped down onto there with a black beer connector clamped down on the other side. Any suggestions? I've already cleaned the line with a keg and some CO2, but I would prefer to not use CO2 and tie up my kegs with sanitizer.
