Although cold temperatures generally cause things to contract, ice has more volume than water so when water freezes inside a pipe, it expands and increases pressure inside the pipe. The building pressure needs to escape so it literally bursts right out of the pipe.
What causes pipe burst?
The basic answer is that the water coming into your house from the outside is much colder than it was during the summer months. The cold water causes your pipes to contract and in weaker parts, can cause the pipe to burst. This happens because the pipe becomes unable to withhold the water pressures inside it.

Can pipes burst if water turned off?
Shutting off the water will not keep the pipes from freezing. The water in the pipes could still freeze and burst the pipe. However, shutting off the water can prevent or reduce water damage when a pipe bursts due to freezing and causes water to flow where it’s not wanted.
Do pipes always burst if they freeze?
A: Frozen pipes do not always burst, if the expanding ice can push water out through an open faucet. However, pipes freeze quite quickly, so the time between freezing and bursting can be very short.
Will pipes burst if they freeze?
Although common, frozen pipes do not always burst. However, the ice can increase this risk when it thaws and is usually worsened as it raises pressure further which makes pipe bursting common near winter’s end or springtime. Furthermore, the more water flowing through the pipe, the greater chance of rupture.
Should you turn off water if pipes are frozen?
If a water pipe has frozen and burst, turn off the water at the main shut-off valve in the house. Thaw pipes and meters by applying hot air from a hair dryer, electric heater or by using a heating pad. Never use hot water or a blowtorch on a frozen pipe or water meter.
What does a bursting pipe sound like?
Metallic sounds like clangs and rattles are common when a pipe bursts. Water shakes the pipe when a burst occurs, so you hear more noises from the pipes when it bursts. Most of the time, new pipes are silent, so listen for changes if you notice any of the other signs.
How long does it take to fix a burst pipe?
