I have FOUR hose bibs on my house. All have Freeze Misers on them. There are two in the yard that MIGHT be hooked to the sprinkler system, I'm not sure. Those have Freeze Misers on them as well, just in case. (I started using these two or three years ago when my well-insulated outdoor hose bibs froze anyway.)
The sprinkler system has been shut off, and I've turned water off to it and my backflow preventer has been removed and is in the garage. The guy who works on my sprinkler system had a lot of clients had theirs stolen after the last freeze so now he installs them so that they're removable.
Depending on how cold it gets, I may drip the inside water faucets.
