How do I shut off the water spigot to the outside?
Assuming you're going to be in the house and it's going to be heated all winter, this should do.


Shut off water supply to house.  There is commonly a valve in the basement for this.
Open the water spigot outside.
Open any spigot or sink below it and let the water come out until it stops.
Close the water spigot outside and put one of those styrofoam covers on it from home depot.
Turn water back on to the house.
