Comment on Absuing a keg as a bung valve
evasive_chimpanzee@lemmy.world 4 months agoThat probably shouldn’t happen, cause it would pull a vacuum on your beer (wonder what effect that would have). It might be able to pull a siphon for a short time, and then cut off. You would then have like an oscillation of pressure on your beer which probably isn’t ideal. Definitely a good move to put the can higher.
I wonder if there’s a good way to prevent any siphoning from going the other way.

Uh, I haven’t even thought about the possibility of reverse siphoning. Maybe better I’d better leave the can where it is? To my understanding, siphoning “uphill” is way harder (if even possible at all, given a specific liquid, height, tube diameter etc). The possible pressure oscillation sounds less “threatening” to me right now.
