Or buy one of those 'spensive heated hoses! That red faucet looks like a no freeze faucet. If the hose is detached, the water will drain out down below the frost line. I have one of those ouside my horse barn. Even so, up north where we are I have the pipe wrapped with heat tape, as well as detaching the hose. Another trick, blow all the water out of the hose after detaching. Beware if itis a metal fitting!
(remember sticking your tongue to a metal railing in winter? Well maybe not in some parts of the continent)
Anyway, I have a small air pump used for inflating exercise balls. Goes in the end of the hose, pump a few time and no more water in the hose to freeze. But you have to be quick when it is 40 below!
