I bought a Speidel fermenter. I love it, but I can't figure out why the airlock doesn't behave like my carboy's airlock. The spigot allows me to take samples easily, and although it is obvious that fermentation is occuring, the airlock won't move. When the beer begins to reach final gravity the air lock will remained suspended (imagine the airlock moving upwards and not falling back down). I wonder if I can't get the seal on the lid correctly.
Has anyone else experienced this?
