Recently picked up a super sucker antigravity siphon pump, and it works pretty good with water, cleaner, and sanitizer but as soon as I started sucking beer with it to move it from the fermenter to the keg I get foam on the discharge. Prior I ran cleaner, water, & Starsan through without issue.
I went ahead with filling the kegs & let the keg foam over until full while occasionally hitting them with co2. What got me was after filling the kegs I took the same exact setup at the same elevations and sucked water then cleaner then starsan without foaming issues. What gives? Figured if anything was gonna foam would have been the Starsan. I’ve never experienced this before with gravity/auto siphon. With both end of the hose submerged and no air leaks presumably why the foaming ?
