We do take steps to protect the outside hose pipes from freezing. House is on a slab so no real risk of freezing from below, never had a problem with any in teh attick.
We have an in ground pool. I have the pumps on timers & they run for a while in the AM, when we get hard freezes like this I turn them on all night to make sure no exposed pipes freeze.
It's not too bad to deal with, moving & covering plants & such
