Protect your plumbing from freezing temperatures and burst pipes
Winter brings some of the most destructive plumbing emergencies. When temperatures drop below freezing, water inside pipes can freeze and expand, creating tremendous pressure that causes pipes to crack or burst. A single burst pipe can flood your home, causing tens of thousands of dollars in damage. Understanding how to protect your plumbing from freezing temperatures prevents costly emergencies.
Water expands approximately nine percent when it freezes. In an enclosed pipe, this expansion creates enormous pressure. While copper and plastic pipes have some flexibility, the pressure from freezing water exceeds their limits. Pipes don't typically burst at the point where ice forms, but rather where pressure builds between the ice blockage and a closed faucet. This pressure can exceed 4,000 psi, far beyond what most pipes can withstand.
Certain pipes face higher freezing risk than others:
The best time to protect pipes is before freezing weather arrives:
Pipe insulation is inexpensive and easy to install. Foam pipe sleeves slip over pipes, creating a thermal barrier that slows heat loss. Pay particular attention to pipes in unheated areas, along exterior walls, and in crawlspaces. Even a few dollars of insulation can prevent thousands in water damage.
Cold air infiltration creates cold spots where pipes freeze. Seal cracks and gaps around pipes where they enter your home. Check the foundation, sill plates, and exterior walls for openings. Use caulk, spray foam, or weatherstripping as appropriate for each location.
Remove, drain, and store garden hoses before winter. Disconnecting hoses allows hose bibs to drain completely. Water trapped between a faucet and hose can freeze, damaging both the faucet and the pipe connected to it.
If your home has older outdoor faucets, consider replacing them with frost-free models. These faucets extend into heated interior spaces, preventing water from sitting in vulnerable locations.
Know where your main water shut-off valve is located and ensure it works. If a pipe bursts despite precautions, you must stop water flow immediately. Test valve operation before emergencies occur.
Shut off and drain outdoor water supply lines for sprinklers, pools, and fountains. These systems hold water that can freeze and damage components.
When temperatures drop, take additional protective measures:
Keep your thermostat set to at least 55 degrees Fahrenheit, even when away. The cost of heating is far less than the cost of water damage. If you're leaving for extended periods, consider having someone check your home daily.
Allow warm air to circulate around pipes in cabinets under sinks. This simple step can prevent freezing in pipes along exterior walls. Remove any chemicals or cleaners stored under sinks if you have children or pets.
During severe cold, allow faucets served by pipes along exterior walls to drip slightly. Moving water resists freezing better than standing water. The minimal water cost compares favorably to burst pipe repairs.
If your garage has water supply lines, keep garage doors closed to retain warmth. Attached garages can be a significant source of cold air infiltration.
For spaces that cannot be heated by your home's system, consider adding temporary heat sources. Space heaters in crawlspaces or near vulnerable pipes provide protection during extreme cold. Always follow safety guidelines for heater use.
For pipes in areas that cannot be sufficiently warmed, heat tape or cables provide direct heating. These products wrap around pipes and maintain temperatures above freezing. They're particularly useful for pipes in unheated spaces that cannot be moved or insulated adequately.
Despite precautions, pipes sometimes freeze. Knowing how to respond prevents burst pipes:
Frozen pipes may have visible frost, feel cold to touch, or show bulging. If faucets produce little or no water, pipes leading to them may be frozen. Check exposed pipes in crawlspaces, basements, and along exterior walls.
Apply heat gradually using a hair dryer, heat lamp, or portable heater. Start near the faucet end and work toward the frozen section. Never use open flames, torches, or high-heat devices that can damage pipes or start fires. Keep the faucet open so water can flow as pipes thaw.
If you cannot locate the frozen section, if pipes are inaccessible, or if damage is visible, call for professional help. Attempting to thaw pipes in walls or under floors without proper knowledge can cause more damage.
Once pipes thaw, check for leaks throughout your home. Frozen pipes often develop cracks that only become apparent when water flows again. Look for wet spots, listen for running water sounds, and check your water meter for movement when no fixtures are running.
If you suspect damage, turn off your water and contact professionals. It's better to confirm pipes are sound than to discover a leak after leaving for work or vacation.
For homes with recurring freezing problems, consider permanent solutions:
Despite best efforts, winter emergencies can occur. Be prepared:
Preparation prevents most winter plumbing emergencies. For homes in cold climates, protecting pipes is essential maintenance that pays dividends in avoided damage and peace of mind.
