I bought three used kegs along with a bunch of used brewing equipment. When I started cleaning/sanitizing the new kegs, I didn’t pay much attention to the poppet valves, assuming (incorrectly I now realize) that they were all the same. After a lot of cussing and frustration I now realize they aren’t all interchangeable nor are the ball lock valves that are in my kegerator. Is there a hack somewhere that shows me what goes where? Is there some way to know which ball lock valves fit which kegs? If there’s a solution to this I’d gladly pony up a hundy, it’s driving me crazy. Every time I try to clean and sanitize these things I inevitably mix them up or am 100% sure I don’t and then try to hook up to the gas side in the kegerator to check for leaks and it’s a mess. Any help would be greatly appreciated
