What describes a urinal that does not use a cartridge for operation?

• A. Flushometer urinal
• B. Pressure-assisted urinal
• C. Waterless urinal
• D. Cartridge urinal

Answer: (C)

Urinal designs differ in how they flush and manage water. A waterless urinal operates without any water flush, so there’s no flush mechanism to activate and no cartridge-based component necessary for its operation. It relies on the drain trap and seal to control odors, and any cartridge used is typically only for odor control—not for flushing. In contrast, every other type relies on water to create a flush, often via a valve or pressure-driven system, sometimes with a cartridge as part of that flushing mechanism. So the description of one that does not use a cartridge for operation is the waterless urinal.
