Will it be apparent if I have frozen pipes?

A frozen pipe or fitting that has burst from freezing will be readily apparent. They don't just drip or seep unless there is still ice in the pipe, they will gush or spray water.

I bought a used trailer, that wasn't winterized properly, that had a cracked shower valve. That valve leaked very slowly with the water dripping inside the wall and onto the converter. Freeze damage can anything from minor to major. In this case, a very minor leak with major potential issues.
