The temps got down below freezing... turned the breaker to the pump off.. now we don't have water... is it froze we drained the lines

Hi deddie and welcome, it's virtually impossible to just drain water lines and not leave a little in a low pipe or swag so you likely have frozen pipes somewhere. You might want to keep pump breaker off until it warms or you thaw the pipes. Good luck

What kind of pump, above ground or submersible? Did you loose prime?
