Hose Bibb Intelligence

In cold weather be sure to disconnect your hoses from outdoor spigots to prevent bursting your water line.  If it happens, you may not find out until you try to use the spigot.  Listen for the added hiss of a leak during use, inside the wall.  Much better to prevent it. More to it... is wall of spigot unheated, remote or partially heated?  Does weather stay below freezing for more than a day (with no thaw)?  Think!...  and understand the physics.
