Your pipes could be at risk of freezing this winter.

At What Temperature Do Pipes Freeze?

The freezing temperature of water is 32 degrees Fahrenheit. The pipes inside your home, however, are protected from exterior freezing temperatures through your home's insulation. What this means is that it on days where it is 32 degrees outside, it does not necessarily mean that your pipes will freeze.

Typically, your home's pipes begin to freeze when the outside temperature is at least 20 degrees Fahrenheit. Again, this depends on your geographical location. For example, areas that expect lower temperatures have water pipes that are better insulated in inner parts of your home, compared to other areas.

How Long Does It Take For Pipes to Freeze and Burst?

The first thing to think about when answering this question is, what is the exact temperature outside and how long will is it predicted to stay that temperature or lower? As a general rule of thumb, in order for your home's water pipes to freeze, the outside temperature needs to be below 20 degrees, for a total of at least six consecutive hours. How long it will take for your pipes to freeze and burst also depends on your home's insulation, and how deep inside your home your water pipes are located. For example, if you live in a geographical location that usually does not suffer from cold winters, chances are that your water pipes do not have that much insulation to protect them from extreme temperatures. In such cases, the time that it may take for your pipes to freeze and burst may in fact be lower.
