Check me on something.....


The mason jar that was full of Starsan, and my blowoff tube was in is now empty. It didn't evaporate overnight in a sealed chamber and I changed the Starsan out yesterday... I am fermenting in a cornie... any chance of negative pressure pulling it into the cornie? I can't imagine that would be possible but the solution is missing.... no mess in the chamber, no holes in the glass.

?

change in temperature sucked it all back into your fermenter.

Yes it is possible. I don't know the tech. terms for it but from what I understand a differance in temp. or pressure could cause a suction. I've read that most would not worry about the starsan in the beer a mason jar should not do that much damage.

a monkey snuck into your house - kicked over your starsan jar; cleaned up the mess, and put the mason jar back upright.

If your mason jar is higher than your fermenter then gravity can also do the damndest things. Most likely though it was fermenting and then stopped, pressure dropped and sucked it into the fermenter.

its not, its on the floor... I know it has to be something but the obvious doesn't fit the situation... I like the monkey... blame the damned monkeys.

What is the ID of your tubing? I always use a big bore blowoff tube (at least 1" ID) to prevent things like this

well my guess is that if you put a 1/2" dia tubing into water and suck on it, its not that hard. If you put a 1" dia tubing into water and suck on it it would be a lot more difficult to move the water.
