#REDIRECT [[tap (valve)]] |
|||
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. |
|||
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 threaded to match standard garden hoses. |
|||
Most US jurisdictions now require bibcocks to have a [[vacuum breaker]] or [[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. |
