After numerous occasions wrestling with the flutter valve at the bottom of my autosiphon (dry hops always find a way in!), I finally snapped one of the tines. I thought I would have to go on a quest to find this obscure replacement part, when I found a post from user BBBF buried in one of the autosiphon threads from 2010. His tip: drop a dime in the tube as a replacement. Just tried it out and it works like a charm! This is the only place I've seen this mentioned, and I thought it deserved to be shared more visibly. Hope this helps someone else out of an autosiphon jam!
