What are the different parts of a hose bib and how do they work together to control the flow of water?

A hose bib typically consists of a handle, a valve stem, a washer, and a spout. The handle is used to turn the valve stem, which controls the flow of water. When the handle is turned, the valve stem opens or closes, allowing water to flow through the spout. The washer helps create a watertight seal when the valve is closed, preventing leaks. Together, these parts work to regulate the flow of water from the hose bib.
