It almost makes you want to popularize your own design in the hobby just to have your name branded in history. People loved the design, and eventually, the name of the forum member became the name of the overflow design. The design is a great way to ensure that your tank won’t overflow while running quietly this design was popularized by a forum poster who mentioned his setup. One of the standpipes is the main drain to the tank, while the other is an emergency drain. Put simply the Herbie overflow is made up of 2 standpipes.
