IF YOUR PIPES FREEZE, GENTLY THAW THEM Locate and shut off the main water supply valve in case a pipe has broken. Next, open the faucet so that water will flow through the pipe once the area is melted. This will help melt more ice. Gently apply heat with a hairdryer around the pipe.
Why does cold weather result in broken water pipes?
Why Do Pipes Burst in Winter? The ice then expands and pushes the water toward the faucet, causing a significant amount of pressure buildup between the ice blockage inside the pipe and the faucet. Eventually, the pipe can’t take the pressure buildup and it bursts.
What temperature will Indoor pipes freeze?
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.
What causes a water line to crack in cold weather?
As the weather turns cold, water lines tend to expand and contract which weakens the water pipes. If a pipe is already corroded and in a weakened state, it makes sense that the expansion and contraction would cause the pipe to crack.
What happens when water pipes freeze in cold weather?

What happens when your water pipes get cold?
When the air temperature surrounding water pipes drops, the heat from the water inside the pipes transfers out to the cold air. 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.
What to do if your water pipes freeze during a cold blast?
With severe cold, even a tiny opening can let in enough cold air to cause a pipe to freeze. Use an indoor valve to shut off and drain water from pipes leading to outside faucets. This reduces the chance of freezing in the short span of pipe just inside the house.
What causes water heater to burst in cold weather?
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.
Where is the best place to freeze a water line?
System design and installation A few common locations where pipes freeze are: outdoor hose bibs, swimming pool supply lines, fire protection lines, and water supply pipes in unheated interior areas, including basements, crawlspaces, attics, garages, bathroom sink cabinets, and kitchen cabinets.
