Which of the following is an example of a continuous demand outlet?

A continuous demand outlet refers to a plumbing fixture or system that consistently uses water over an extended period rather than in intermittent bursts. In this case, the hose bibb is the most fitting example of a continuous demand outlet. This fixture is often used for outdoor watering, irrigation systems, or filling large containers, where water may flow continuously for longer durations as needed.

While the toilet flush, dishwasher, and faucet do use water, they primarily operate in a cycle of use and non-use, meaning they do not typically maintain a steady flow of water over time. The toilet flush operates with a single demand for water when flushed and then becomes inactive until the next use. Dishwashers run a cycle for a specific time but do not continuously draw water, and faucets, although they can allow water to flow continuously when turned on, are generally intended for intermittent use based on user demand.

Therefore, the hose bibb exemplifies a continuous demand outlet as it is more likely to be used for prolonged water flow without frequent user initiation.
