Define “fixture” in plumbing terminology.

In plumbing terminology, a "fixture" refers to any outlet or device that is connected to a water supply or drainage system. This definition encompasses a wide range of items commonly found in residential and commercial settings, such as sinks, toilets, showers, and bathtubs. Fixtures are integral components within plumbing systems because they serve as the points where water is dispensed or waste is drained, thereby facilitating user interaction with the water supply.

Understanding the role of fixtures is crucial for properly designing, installing, and maintaining plumbing systems, as they must be adequately connected to the necessary supply and drainage lines to function effectively. The definition captures the essence of how fixtures contribute to the overall plumbing infrastructure, ensuring both functionality and compliance with plumbing codes and regulations.

Other options do not align with the accepted definition of fixtures in plumbing. For instance, a type of pipe used in large systems does not represent a fixture; instead, it refers to part of the plumbing infrastructure. An attachment for holding tools is unrelated to the concept of fixtures, which focuses on water outlets and devices. Lastly, while decorative items may be found in bathrooms, they do not serve the plumbing function associated with the term "fixture."
