Frozen Pipes??

Frozen pipes are one of the most common and costliest property damage events during the cold winter months. In fact, a burst pipe can result in tens of thousands of dollars in damage. Fortunately, frozen pipes can be prevented quite easily and inexpensively.

How do Pipes Burst?

Contrary to popular belief, pipes do not typically burst where the ice blockage is located. The expansion of the ice against the wall of the pipe does not cause it to break. Rather, after a complete ice blockage in a pipe occurs, the continued freezing and expansion inside the pipe causes water pressure to increase downstream, between the ice blockage and a closed faucet at the end. This increase in water pressure is what causes the pipe to fail. Usually the pipe bursts where little or no ice has formed. Upstream from the ice blockage the water can always flow back towards its source, so there is no pressure build-up to cause a break. Water has to freeze for ice blockages to occur. Pipes that are adequately insulated along their entire length are usually safe from freezing.

Which Pipes are Susceptible to Freezing?

Generally, homes and structures in northern climates are built with the water pipes located inside the building insulation, which protects the pipes from subfreezing weather. However, ex­tremely cold weather and holes in the building that allow a flow of cold air to come into contact with pipes can lead to freezing and bursting.

Pipes in attics, crawl spaces and outside walls are all vulnerable to freezing, especially if there are cracks or openings that allow cold, outside air to reach the pipes. Research has shown that “wind chill,” can accelerate the freezing process.

Holes in outside walls where television, cable, or phone lines enter can allow cold air to reach pipes. When should you be alert to the danger of freezing pipes? That depends on the climate where you live, but the “temperature alert threshold” is 20 degrees F.
