Abstract: An improved leak guard for preventing damage to a building caused by a ruptured conventional sillcock, wherein the sillcock has a tube, a valve within the tube and a control knob at one end of the tube operably coupled with the valve. The leak guard includes a tubular connector interconnecting the tube of the sillcock and the supply line for establishing fluid communication therebetween and a housing sealingly secured to the connector. The housing has an internal chamber for receiving the tube of the sillcock when the sillcock is connected to the connector. Further, the housing has an outlet disposed to be located outside the building when the guard is installed for directing leaking water from the sillcock to a point outside the building.
