Which of the following is NOT a typical plumbing fixture?

The correct answer is that an interceptor is not typically considered a plumbing fixture. Plumbing fixtures, such as toilets, sinks, and bidets, are devices specifically designed for direct use by individuals for sanitation, personal hygiene, or other daily activities.

A toilet is a common fixture found in nearly every household, designed primarily for waste disposal. A sink serves multiple purposes, from washing hands to food preparation, and is also widely used. A bidet, while less common in some regions, is a recognized fixture that facilitates personal hygiene.

In contrast, an interceptor is a device used in plumbing systems to separate certain substances from wastewater, often preventing them from entering the sewer system. For example, grease interceptors are installed in kitchens to trap grease from food preparation activities. While interceptors are crucial for maintaining the plumbing system and environmental regulations, they do not serve as direct user-facing fixtures like the other options listed.
