What is a 'Combination Fixture'?

A 'Combination Fixture' refers to a plumbing installation that includes multiple compartments, typically two or three, designed for use together and drained by a continuous waste system. This setup allows for efficient drainage while keeping the compartments interconnected, which is particularly useful in commercial settings like restaurants or laboratories where multiple wash areas are necessary.

This design minimizes the complexity of drainage systems and helps in managing waste more effectively. The continuous waste means that any water or waste can flow seamlessly from one compartment to another before reaching the main drainage system, reducing the potential for clogs and ensuring better hygiene.

Other choices represent different plumbing concepts, such as a single sink with multiple drains, which doesn’t qualify as a combination since it's less about compartments and more about drainage points. A sink drained by a single trap might suggest a simpler setup without multiple compartments. Lastly, a fixture combining sink and toilet functions indicates a unique device but doesn't align with the definition of a combination fixture focused on compartment systems.
