A '''bibcock''', also called a '''sillcock''', is commonly used to provide [[hose]] connections outside of buildings, for use in gardening, watering lawns, washing cars, and so on. Certain bibcocks are colloquially known as '''frost-frees''' because they are immune to all but the worst [[freezing]] conditions. |
|||
A bibcock can be any of several [[valve]] types; commonly they have a removable control knob that pushes a rubber plug against an opening in order to close the valve. The downstream side of the valve is [[Screw thread|threaded]] to match standard [[garden hose]]s. |
|||
Most U.S. jurisdictions now require bibcocks to have a [[vacuum breaker]] or [[Backflow prevention device|backflow preventer]], so that water cannot return through the bibcock from the hose. This prevents contamination of the building or public water system should there be a pressure drop. |
