Abstract

Various embodiments of a cartridge for regulating a fluid flow are described that include an upper housing, and an insert that is user-removable from the upper housing. The cartridge can include one or more valves that are biased in a closed position to prevent odors from escaping the cartridge. The cartridge can also include a fluid trap that is at least partially disposed within the cartridge or fluidly coupled thereto. An ultraviolet light can be inserted within the cartridge to disinfect a fluid passageway of the cartridge.
