Tips to Prevent and Protect Pipes from Freezing During The Winter
Why Pipe Freezing is Such a Problem
Water has a unique property going from a liquid to a solid it expands as it freezes. This expansion causes 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.
Most frequently pipes that freeze are:
Pipes that are exposed to severe cold, like outdoor water faucets, swimming pool supply lines, and water sprinkler lines.
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.
How to Help Pipes From Freezing
Before the onset of cold weather, protect your pipes from freezing by following these recommendations:
Drain water from swimming pool and water sprinkler supply lines following manufacturer's or installer's directions. Do not put antifreeze in these lines unless directed. Antifreeze is environmentally harmful, and is dangerous to humans, pets, wildlife, and landscaping.
Remove, drain, and store hoses used outdoors. 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.
Add insulation to attics, basements and crawl spaces. Insulation will maintain higher temperatures in these areas.
Check around the home for other areas where water supply lines are located in unheated areas. Look in the 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.
Consider relocating exposed pipes to provide increased protection from freezing.
How to Prevent Frozen Pipes
Keep garage doors closed if there are water supply lines in the garage.
Open bathroom and kitchen cabinet doors to allow warmer air to circulate around the plumbing. When the weather is very cold outside, let the cold water drip from the faucet served by exposed pipes. Running water through the pipe - even at a trickle - helps prevent pipes from freezing.
Keep the thermostat set to the same temperature both during the day and at night. By temporarily suspending the use of lower nighttime temperatures, you may incur a higher heating bill, but you can prevent a much more costly repair job if pipes freeze and burst.
If you will be going away during cold weather, leave the heat on in your home, set to a temperature no lower than 55° F.
