What happens when pipes freeze and burst?

What happens if pipes freeze in house?
When water in a pipe freezes, it expands and puts tremendous pressure on both metal and plastic pipes. If the pipe breaks, it can easily release a torrent of water into the building.

Why do hot water pipes freeze first?

Will pipes freeze at 30 degrees?
Water freezes at 32 degrees Fahrenheit, but indoor pipes are somewhat protected from outdoor temperature extremes, even in unheated areas of the house like in the attic or garage. … As a general rule, temperatures outside must drop to at least 20 degrees or lower to cause pipes to freeze.
Will PVC pipes burst if frozen?
