Fitting an external tap is not really hard

One comment I would add is to ensure the pipe is well insulated. Our
outside tap here in Normandy is a copper pipe out of the ground up the
side of the wall. It has two layers of pipe insulation wrapped around
it. It survived the harsh Winter we had here without problem. A similar
outside tap in England burst its pipe during a mild Winter due to lack
of lagging.

In the winter we turn off the water at the tap inside, then three-
quarters open the external tap that way any water freezing is not
confined within the pipework also as the tap is connected by hose not by
"inflexible" copper pipe so any freezing that does occur in the
connection will just expand the hose rather than bursting any copper pipe.
