The most wonderful time of the year

Pipes freeze when the water inside is cold enough to solidify. In extremely cold weather, pipes can freeze in a matter of minutes.  If water is flowing through the pipe it requires a lot more work to make it freeze and is not very common.  In a home a pipe is likely to freeze if it is near outer walls, low to the ground, gaps in insulation or where air flow from the outside is possible.  

Usually  only a small section of the pipe freezes.  Water expands as it freezes; the expansion starts by increasing in length along the pipe.  If the pipe has bends in it, the ice that forms is less likely to expand away from the cold.  A section of water can become trapped and the pressure in that section increases, once the pressure is too high the pipe will burst.  

A few tips to Prevent pipes from freezing: Leave tap open/dripping on pipes that freezing could occur.  Leave the space around the pipes as open as possible.  Ensure your heat is on I all areas of you home.  Insulate all areas of your home well. If the temperatures decrease a additional heater may be needed.
