Non-Circulating System - Floater (Version 2) - Spyder3D World
Version 2 of the Floater has a spot for rubber padding to ensure a better seal. When the water level rises, it floats and blocks more water from entering the reservoir. When the reservoir is empty, the Floater does down and allows more water to enter.
