At What Temperature Does An Outside Faucet Freeze?

The outside faucets are likely to freeze at 32 degrees F or 0 degrees C. An exposure of around 6 hours to freezing temperatures can cause freezing water in the outside pipes. To prevent the issues such as a burst pipe or cracked hose bibb, it would be a great option to help you in freezing the weather arrives. 

Pipes are likely to burst when exposed to freezing temperatures. Interior pipes are generally safe even at temperatures as low as 20 degrees F or at minus 7 degrees F. However, the outdoor faucet can freeze at temperatures as low as 32 (0) when exposed for at least 6 hours. 

It is advisable to check the following factors when you find outdoor faucets:

  • The exterior water supply pipes can freeze and burst at the temperatures when they go below 32 (0) for 6 hours or longer.
  • The interior pipes are at risk of freezing when temperatures go below 20 (-7).
  • In some areas, the internal pipes can also burst when the temperatures reach the point of freezing.

What Happens If My Outside Tap Freezes?

A frozen pipe can cause several issues and can result in the loss of thousands of dollars of money. A few of the problems that you may come across when your outside tap freezes can include bursting of pipes, broken valves and broken joints. It can even cause a leakage inside your home. 

The sections that are impacted by the freezing in the pipes can result in a huge number of issues that include swell, crack, or burst, creating major water leaks when the water inside thaws. The water leakage within the walls can result in a few other issues such as rotten wood or building materials and even mold growth. It is also likely to cause property damage in many cases.

The small amount of running water in the tap can also relieve the pressure inside your pipes and prevent the possibility of over-expansion. Setting up the faucets to drip is one of the excellent options to help you winterize your house.
