How to Prevent Frozen Water 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.

Vulnerable pipes in existing homes should be fitted with insulation sleeves or wrapping to slow the heat transfer. It is important not to leave gaps in the insulation that expose the pipe to cold air. Hardware stores and home centers stock a variety of foam rubber and fiberglass sleeves, in various thicknesses.

When water is colder than 32 degrees Fahrenheit or zero degrees Celsius, it freezes into ice. When water freezes, it expands up to nine percent more than it did when it was water. This expansion puts tremendous pressure on metal or plastic pipes causing pipes to burst and water to leak.

Cracks and holes in outside walls and foundations near water pipes should be sealed with caulking to keep cold wind away from the pipes. Kitchen and bathroom cabinets can keep warm inside air from reaching pipes under sinks and in adjacent outside walls. It’s a good idea to keep cabinet doors open during cold spells to let the warm air circulate around the pipes.
