How Do I Prevent Pipes From Freezing in Winter?

Pipe insulation sleeves made of foam or fiberglass are a key defense. You can find these materials at any hardware store. Apply them to all pipes in unheated spaces like attics, basements, garages, and crawl spaces. Pay special attention to pipes running along exterior walls, as they lose heat quickly.

For pipes inside cabinets on exterior walls, keep the cabinet doors open during cold spells. This allows warmer indoor air to circulate around the plumbing. For added protection in very cold areas, consider using thermostatically controlled heat tape. Always follow the manufacturer's instructions closely for safe installation.

On nights when temperatures are forecast to drop well below freezing, let cold water drip from faucets supplied by exposed pipes. A slow, steady drip relieves pressure within the pipe system. This moving water is much harder to freeze than stagnant water. It is a simple and effective last line of defense.

Focus on faucets that are farthest from where water enters your home. Letting both hot and cold lines drip can be beneficial. Remember, this is a temporary measure for extreme conditions. The small increase in your water bill is minor compared to the cost of repairing a burst pipe.

• Let water drip from faucets on exposed pipes during extreme cold.
• A slow, steady drip from both hot and cold lines is effective.
• Concentrate on faucets located on exterior walls or in unheated rooms.
• This relieves pressure, making a pipe less likely to burst if it freezes.
• The cost of the extra water used is minimal.
• This is a temporary measure, not a substitute for proper insulation.

If a pipe freezes, turn on the faucet to allow water to flow as it thaws. Gently warm the frozen section using a hair dryer, a heating pad, or towels soaked in warm water. Start warming the pipe closest to the faucet and work toward the frozen area. Never use a blowtorch, kerosene heater, or other open flame.

If a pipe has burst, immediately turn off the main water shutoff valve to stop the flow. Then, call a local plumber to repair the broken pipe. For the resulting water damage, local water damage pros can help with extraction and drying. Quick action minimizes damage to your home's structure and belongings.
