Water has a unique property in that it expands as it
freezes. This expansion puts tremendous pressure on whatever is containing it,
including metal or plastic pipes. No matter the "strength" of a
container, expanding water can cause pipes to break. Pipes that freeze most
frequently are those that are exposed to severe cold, like outdoor hose bibs,
swimming pool supply lines, water sprinkler lines, and water supply pipes in
unheated interior areas like basements and crawl spaces, attics, garages, or
kitchen cabinets. Pipes that run against exterior walls that have little or no
insulation are also subject to freezing.
Before the onset of cold weather, prevent freezing of these
water supply lines and pipes by following these recommendations:
-Close inside valves supplying outdoor hose bibs. Open the
outside hose bibs to allow water to drain. Keep the outside valve open so that
any water remaining in the pipe can expand without causing the pipe to break.
-Check around the home for other areas where water supply
lines are located in unheated areas. Look in the basement, crawl space, attic,
garage, and under kitchen and bathroom cabinets. Both hot and cold water pipes
in these areas should be insulated.
-Consider installing specific products made to insulate
water pipes like a "pipe sleeve" or installing UL-listed "heat
tape," "heat cable," or similar materials on exposed water
pipes. Newspaper can provide some degree of insulation and protection to
exposed pipes – even ¼” of newspaper can provide significant protection in
areas that usually do not have frequent or prolonged temperatures below
freezing.
