I broke out my new 30L Speidel fermenter yesterday to use on a dry stout recipe that I brewed. After cleaning and sanitizing the airlock, I filled it up with Starsan to the fill line and quickly noticed that Starsan was running out the bottom tube of the airlock. At first I thought that it might be a design to prevent the airlock from overflowing but I realized that it appears to be a manufacturing defect. Here is a picture of the leak right down the tube. Fortunately, I had another airlock and was able to swap it out. Has anyone had an issue like this before?
