The extreme cold and winter storms that have blanketed much of the U.S. are causing a host of problems for homeowners — everything from where to put several feet of snow when shoveling to preventing ice dams and leaks on snow-covered roofs.

Another issue impacting a lot of residents involves frozen water pipes. As the water in pipes freezes, it expands, creating as much as 2,000 pounds of pressure per square inch, enough to cause almost any pipe filled with water to rupture. The bad news is that a burst pipe can release hundreds of gallons of water per hour, causing thousands of dollars in damage to repair.

At-risk are pipes in unheated parts of a building, exposed pipes, those in or along outside walls of a structure, pipes under a sink by an outside wall, and any in unheated attics or crawlspaces. Pipes in townhomes, single-family homes and multi-family units can freeze under the right circumstances.
