Preparing your home for winter is essential in the Flathead Valley, where prolonged cold snaps are common. One of the most important steps homeowners can take is protecting plumbing from freezing temperatures. Frozen pipes can lead to serious water damage, but with the right preparation, the risk can be greatly reduced. Below are practical, proven steps to help prevent frozen pipes during winter.
Why Frozen Pipes Are Dangerous
When outdoor temperatures drop below 32 degrees Fahrenheit for extended periods, water inside pipes can freeze. As water freezes, it expands and creates significant pressure inside the pipe.
This pressure can cause pipes to crack or split. When the ice eventually thaws, water can escape rapidly from the damaged section, leading to flooding. Burst pipes can cause extensive structural damage and create conditions that encourage mold and mildew growth.
Pipes Most at Risk of Freezing
Not all pipes face the same level of risk during winter. Outdoor plumbing components such as hose bibs, faucets, and sprinkler lines are especially vulnerable because they are directly exposed to cold air.
Indoor pipes located in unheated or poorly insulated areas are also at higher risk. These areas often include attics, exterior walls, basements, crawl spaces, and garages. Pipes near drafty windows, doors, rim joists, or foundation cracks are more likely to freeze due to cold air infiltration.
Shut Off Outdoor Plumbing Lines
One of the first steps in preventing frozen pipes is shutting off water supply lines to outdoor fixtures. Many homes have shut-off valves with bleeder valves that allow excess water to drain from the line.
After shutting off the water, open the bleeder valve to empty the pipe completely. Disconnect and store garden hoses in a dry location to prevent trapped water from freezing.
Insulate Exposed Pipes
Pipe insulation is one of the simplest and most effective ways to prevent freezing. Foam pipe sleeves, rubber insulation, and fiberglass wraps help retain heat and slow heat loss from the pipe.
Focus on insulating pipes in garages, basements, exterior walls, crawl spaces, and attics. In areas prone to severe cold, heat tape or heating cables may be added. These products provide gentle warmth when pipe temperatures approach freezing.
Seal Drafts and Air Leaks
Cold air drafts significantly increase the risk of frozen pipes. Sealing gaps where pipes pass through walls, floors, or foundations helps block cold air movement.
Common sealing materials include caulk, weather stripping, and spray foam. Pay special attention to areas near rim joists, utility penetrations, windows, and doors where drafts are most likely.
Keep the Heat On
If you plan to travel during winter, it may be tempting to turn off the heating system. Doing so increases the risk of frozen pipes.
Instead, maintain a consistent indoor temperature of around 55 degrees Fahrenheit. This setting helps protect plumbing while keeping energy use reasonable.
Take Extra Steps During Severe Cold
During extreme cold spells when temperatures drop into the teens or single digits, additional precautions can help.
Opening cabinet doors under sinks allows warm indoor air to circulate around pipes located near exterior walls. Letting a faucet drip slightly overnight can also help, as moving water is less likely to freeze than standing water. Choose the fixture farthest from the main water supply to keep water moving through most of the system.
Signs a Pipe May Be Frozen
Even with precautions, pipes can still freeze. Early detection helps limit damage. Common warning signs include little or no water flow from a faucet, visible frost on exposed pipes, and unusual sounds when turning on taps.
What to Do If a Pipe Freezes
If you suspect a frozen pipe, open the faucet connected to that section slightly. This allows pressure to escape as the ice melts.
Apply gentle heat using a hair dryer or warm towels. Never use an open flame, as it can damage pipes and create a fire hazard. Warm the pipe gradually until water flow returns. Inspect the pipe for cracks, bulging, or leaks. If any damage is visible, contact a professional immediately.
Consider Smart Leak Detection
Smart leak detection systems provide added protection. Sensors placed near plumbing fixtures monitor for moisture and send alerts if a leak is detected.
Some systems include automatic shut-off valves that stop water flow when a leak is identified, helping prevent major water damage while you are away.
