There won't be water running inside while the pipes are still frozen. The ice in the pipe is sealing the crack, if there is one. When the outside temps start rising above freezing, The ice in the pipe will melt and unseal the crack. That's when the water will pour into the house. Years ago, there was a similar situation when there was a long spell of below freezing weather (I don't think it was as long as the current spell) pipes in numerous houses belonging to 'snowbirds' (people who spend the winters in Florida) froze because no one was home to see that there was no water running which would indicate a frozen pipe. When the warmer weather replaced the freezing weather, the ice in the pipes melted and the water flowed out of the pipes. Neighbors noticed water running out of the houses from under the garage doors and burst sillcocks.
