Winter in the Pacific Northwest may be milder than other parts of the country, but freezing temperatures still pose a real risk to plumbing systems. Homeowners across Seattle and the surrounding areas often underestimate how quickly pipes can freeze during cold snaps, especially overnight or during extended absences.
Taking a few proactive steps before winter sets in can help you avoid frozen pipes, burst plumbing lines, and costly water damage.
Why Frozen Pipes Are a Risk in Seattle Homes
Seattle homes are particularly vulnerable to frozen pipes because many properties were not built for prolonged freezing conditions. Pipes located in basements, crawlspaces, garages, exterior walls, or unheated areas are especially at risk.
When water freezes, it expands. That expansion puts pressure on pipes, often causing cracks or bursts that lead to flooding once the ice thaws.
Insulate Exposed Pipes
One of the most effective ways to prevent frozen pipes is proper insulation. Pipes in unheated areas should be wrapped with foam insulation sleeves or heat tape designed for plumbing use.
Pay close attention to pipes near exterior walls, in crawlspaces, and under sinks. Insulation helps maintain consistent temperatures and reduces exposure to cold air.
Protect Outdoor Faucets and Hose Bibs
Outdoor faucets are often the first place freezing damage occurs. Before winter arrives, disconnect all garden hoses and drain any remaining water. Install insulated faucet covers to protect exposed fixtures from freezing temperatures.
For added protection, consider upgrading to frost-free hose bibs, which are designed to shut water off deeper inside the wall where temperatures are warmer.
Seal Drafts and Air Leaks
Cold air entering your home can quickly lower temperatures around pipes. Check for drafts near plumbing lines, especially around windows, doors, vents, and foundation gaps.
Sealing cracks and openings with caulk or weatherstripping helps keep cold air out and warm air in, protecting both your pipes and your energy efficiency.
Maintain a Consistent Indoor Temperature
During cold weather, keep your thermostat set to a consistent temperature, even when you are away from home. Turning heat too low overnight or while traveling increases the risk of freezing, particularly for pipes in exterior walls.
Opening cabinet doors under sinks can also help warm air circulate around plumbing during colder nights.
Let Faucets Drip During Extreme Cold
When temperatures drop significantly, allowing faucets to drip slightly can help prevent freezing. Moving water is less likely to freeze than standing water and helps relieve pressure inside the pipes.
This is especially helpful for fixtures connected to plumbing located along exterior walls.
Know Where Your Main Water Shutoff Is
In the event a pipe does freeze and burst, knowing how to quickly shut off your home’s water supply can minimize damage. Make sure everyone in your household knows where the main shutoff valve is located and how to use it.
If you are unsure or have trouble locating it, a professional plumber can help.
