Can cold weather cause pipes to burst?
However, ex- tremely cold weather and holes in the building that allow a flow of cold air to come into contact with pipes can lead to freezing and bursting. Water pipes in houses in southern climates often are more vulnerable to winter cold spells.
Will pipes burst at 50 degrees?

How cold is too cold for house pipes?
Information varies on how cold it has to be for pipes to freeze, but the freezing temperature of water is 32 degrees. So, theoretically, your pipes could freeze at any temperature lower than that. But for your pipes to literally freeze overnight, the temperature would probably have to drop to at least 20 degrees.
Will pipes automatically burst if they freeze?
It’s important to note that pipes do not always burst once they’re frozen or while in the process of freezing. After a pipe has frozen and begins to thaw, the pressure caused by the water that begins to rush through the pipe threatens to cause a pipe to burst.
Where do pipes usually burst?
Pipes that are the most at risk of bursting are those located outside of building insulation, or those in unheated interior areas, including basements, attics and crawl spaces. Heating or insulating these vulnerable pipes with fiberglass or foam sleeves can help prevent them from bursting.

What causes water pipes to burst in cold weather?
As the water heat transfers to the cold air, the water temperature drops to the point that it starts to freeze. Ice in the pipes causes a pressure backup, which can cause the pipe to burst.
