Also, do not strike pipes in an attempt to break up the ice, as hammer blows can cause pipes to crack.
Why would hot water pipe freeze before cold?
If the water is initially hot, cooled water at the bottom is denser than the hot water at the top, so no convection will occur and the bottom part will start freezing while the top is still warm.
