3-piece airlocks and blow-off tubes may suck in liquid. That's relatively easy to avoid. The more complicated problem is preventing oxygen from getting inside.I have never noticed any liquid being sucked into my fermentors before. Are people saying this is worse when using a blow off tube?
All these plastic or silicone devices that prevent air getting in still let through a lot of oxygen.
They probably help to some degree, but it'd be like using a blow-off that only sucks in a few cups of sanitizer instead of a gallon.
