Pex pipe vs. winter woes: will it freeze and shatter?

PEX, or cross-linked polyethylene, is a type of plastic piping commonly used in plumbing systems. Its flexibility and durability make it a popular choice for both residential and commercial applications. However, one question that often arises is: does PEX pipe freeze and break?

The answer is: yes, PEX pipe can freeze and break. However, it is less likely to do so than other types of piping, such as copper or PVC. This is because PEX is a flexible material that can expand and contract without cracking.

Factors That Affect PEX Pipe Freezing

Several factors can affect the likelihood of PEX pipe freezing and breaking, including:

• Temperature: The lower the temperature, the more likely PEX pipe is to freeze.
• Exposure to cold: PEX pipe that is exposed to cold air or water is more likely to freeze than pipe that is insulated or buried underground.
• Water pressure: High water pressure can cause PEX pipe to expand and contract more rapidly, which can lead to freezing.
• Pipe size: Smaller diameter PEX pipe is more likely to freeze than larger diameter pipe.

How to Prevent PEX Pipe from Freezing

There are several things you can do to prevent PEX pipe from freezing, including:

• Insulate exposed pipes: Use foam insulation or heat tape to insulate any PEX pipe that is exposed to cold air or water.
• Bury underground pipes: If possible, bury PEX pipe underground below the frost line.
• Drain pipes before cold weather: Drain any water from PEX pipes before cold weather arrives.
• Use a heat source: If you are concerned about PEX pipe freezing, you can use a heat source, such as a heat lamp or space heater, to keep the pipe warm.

What to Do if PEX Pipe Freezes

If PEX pipe does freeze, there are a few things you can do to thaw it out:

• Use warm water: Pour warm water over the frozen pipe.
• Use a heat gun: Use a heat gun to gently warm the frozen pipe.
• Call a plumber: If you are unable to thaw the frozen pipe yourself, call a plumber for assistance.

Summary: PEX Pipe and Freezing

PEX pipe is less likely to freeze and break than other types of piping, but it is still possible. By taking steps to prevent freezing, you can help to ensure that your PEX pipe remains in good condition for many years to come.
