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.
How cold does it have to be for pipes to burst?
This can happen any time the air surrounding the pipes reaches below freezing, which is 32 degrees Fahrenheit. 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.
Why do water pipes burst in winter?

Can pipes burst in winter?
When temperatures plummet, the risk of your pipes freezing and bursting skyrockets. In fact, burst pipes are one of the most common causes of property damage during frigid weather and can cause thousands in water damage—easily $5,000 or more, according to the Insurance Institute for Business and Home Safety (PDF).
What makes water pipes burst?
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.
Will pipes freeze in one night?
Pipes can freeze in as little as six to eight hours, meaning they can freeze overnight. If the outside temperature is below 32 degrees F and your pipes are unprotected, your chances for a frozen pipe increase.
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.
Will shutting off water keep pipes from freezing?
To prevent pipes from freezing, the best thing to do is turn your water off if you can locate your valve. If not, leaving your faucets on with a slight trickle – not a drip – to prevent broken pipes, he says.

Check the functionality of your plumbing. An open faucet that produces a slow trickle—or no water at all—is a good reason to suspect that a pipe has frozen. Also check the water meter; if it shows movement when all water fixtures are off, it is likely that a pipe has burst.
What temperature should I keep my house in the winter so the pipes don’t freeze?
Set your thermostat at 70 degrees Seventy degrees Fahrenheit is the optimal temperature to prevent frozen pipes, even in below-zero temperatures.
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 do you do when a water pipe bursts?
Things to Do About a Burst Pipe Turn off main. Before anything else, turn off the water supply. Call a plumber. Next, call a plumber. Clean the water. Clear away any water quickly to avoid excess water damage. Drain faucets. Let in warm air. Keep doors open. Repair sleeve. Rubber, wood piece, and clamp.
At what temp should you drip faucets?
When a cold wave hovers around or below 20 degrees Fahrenheit (-6 degrees Celsius), it’s time to let at least one faucet drip. Pay close attention to pipes that remain in attics, garages, basements or crawl spaces because temperature levels in these unheated interior areas usually imitate outside temperatures.
How long can pipes be frozen before they burst?
How Long Can a Pipe Stay Frozen? A pipe will stay frozen for as long as the temperature around the pipe remains below freezing. This temperature could last for days, weeks, months, or years depending on location. However, for every moment that passes, the pipes run the risk of bursting, which can happen in 4-5 hours.
