Seattle may not be known for harsh winters, but when snowstorms hit, they can wreak havoc on your plumbing system. Sudden temperature drops, freezing rain, and even brief snow accumulation can lead to burst pipes, frozen water lines, and costly plumbing repairs.
Before the next winter weather event hits Puget Sound, here’s a smart homeowner’s guide to preparing your plumbing for a Seattle snowstorm.

🧊 Why Seattle Homes Are Still at Risk for Frozen Pipes
Seattle’s moderate climate makes many homeowners think frozen pipes aren’t a concern. But according to the Federal Emergency Management Agency (FEMA), pipes can begin to freeze when temperatures drop below 20°F — and Seattle often experiences sudden cold snaps below this threshold.

Older homes in neighborhoods like Ballard, Beacon Hill, and Queen Anne are especially vulnerable due to exposed or poorly insulated piping.
✅ 8 Ways to Winterize Your Plumbing Before a Snowstorm
1. Insulate Exposed Pipes
Start with crawl spaces, attics, basements, and garages. Use foam pipe insulation sleeves or UL-listed heat tape to wrap any exposed piping. Focus on pipes running along exterior walls.
🛠️ Tip: Pay extra attention to outdoor spigots and pipes near poorly sealed windows or vents.
2. Disconnect and Drain Outdoor Hoses
Leaving hoses attached can cause water to freeze and back up into the house. Shut off the water to outside faucets and open the valve to let remaining water drain.
3. Seal Drafts Near Pipes
Use weather stripping or caulk to seal gaps around windows, doors, and foundation vents—especially those near plumbing lines.

4. Let Faucets Drip in Freezing Temps
Running a small trickle of warm and cold water through your faucets can help prevent water from freezing inside the pipes during extreme cold spells.
5. Open Cabinet Doors
Allow warm air to circulate around plumbing, especially in kitchens and bathrooms. This is critical for pipes located on exterior-facing walls.
6. Know Where Your Main Water Shut-Off Valve Is
If a pipe does burst, turning off the water immediately can prevent extensive damage. Make sure everyone in your household knows its location.
📌 Tip: It’s often found in the basement, crawlspace, or near the water heater.
7. Check Your Water Heater
Ensure your water heater is operating efficiently. Cold weather increases demand, and a malfunctioning unit could leave you without hot water when you need it most.
8. Schedule a Professional Winter Plumbing Inspection
Proactive maintenance can help you catch small vulnerabilities before they become winter emergencies.

🚨 Signs of Frozen Pipes to Watch For
If a Seattle snowstorm hits and your pipes freeze, you may notice:
- No water flow from faucets
- Frost on visible pipes
- Strange clanking or banging sounds
- Damp spots on walls or ceilings
If you suspect a frozen pipe, turn off your main valve immediately and call a plumbing professional. Delaying can cause the pipe to burst when the ice thaws.
🧰 Emergency Pipe Thawing (Only If Safe to Attempt)
If you can safely access the pipe and it’s not cracked, try:
- A hair dryer (never a blowtorch)
- Heating pad wrapped around the pipe
- Warm towels soaked in hot water
Never use open flames or propane heaters. If unsure, wait for professional help.
