What is a hose bibb?

A hose bibb is indeed a valve designed for outdoor water supply that typically features a threaded nozzle. This type of fixture is crucial for providing easy access to water outside of a building, allowing homeowners to connect a garden hose or other devices for various tasks such as watering lawns, washing vehicles, or filling pools. The threaded nozzle is a standard feature that allows for the attachment of hoses or other fittings, ensuring a secure connection to facilitate the flow of water.

In comparison, the other options do not accurately describe a hose bibb. A type of indoor faucet with multiple outlets does not fit the description or function of a hose bibb, which is specifically meant for outdoor use. A decorative feature in landscaping does not pertain to plumbing fixtures, and a specialized washing fixture typically refers to something like a laundry sink or utility sink, which is also not aligned with the intended use and design of a hose bibb. Thus, the identification of a hose bibb as an outdoor valve with a threaded nozzle is correct and underscores its practical application in everyday tasks.
