(video) A dipper well in use, 2019

A dipper well is a perpetual-flow sink often used in coffeehouses and ice cream shops to rinse utensils.[1] Ice cream scoops and other food-preparation utensils can be placed under the continuous stream in order to remove allergens and protect against bacterial growth.[2] Most dipper wells have a single spigot and can be adjusted for both hot and cold water use. As largely a commercial appliance, dipper well valves are typically kept at full flow during all serving hours.[3] Dipper wells have also been used as key components in pharmacological experimentation.[4]
