Harvested rainwater for non potable use in the home

I was just reading a pretty current plumbing book (plumbing. for pros by pros) and the author talks about how each house is supposed to have a double check valve to prevent back flow of water from the house back in to the main in case of loss of pressure in the main and this double check valve is all that is needed so the cruddy water in your rusty pipes doesn't back feed.
I don't see why a double check valve like that could not be used in your house as well.
