A hose bib is an outdoor water faucet protruding from a building, which is usually threaded to accept a hose connection. Some hose bibs use a soft rubber or neoprene washer which is screwed down onto a valve seat in order to stop the flow. While it gives a leak-proof seal and good fine adjustment of flow, both the rubber washer and the valve seat are subject to wear.
Cone valves or ball valves are commonly found in more-expensive water systems and usually found in gas taps. They can be identified by their range of motion of only 90° between fully open and closed. Usually, when the handle is in line with the pipe the valve is open, and when the handle is across the pipe it is closed.
Most communities now require hose bibs to have a vacuum breaker or backflow preventer, so that water cannot return through the hose bib from the hose.
