Seattle’s unique climate—rainy winters, wet springs, and occasional freezes—makes plumbing issues more than just a nuisance; they can quickly become emergencies if left unchecked. From burst pipes to overflowing toilets, being caught off guard can mean thousands in water damage, mold growth, and structural repairs.
Here are the top 10 plumbing emergencies Seattle homeowners face, how they happen, and what you can do to prevent them before they wreak havoc on your home.
1. Burst Pipes During Freezes
While Seattle winters are milder than other regions, sudden cold snaps can still freeze and burst uninsulated pipes—especially in crawlspaces or exterior walls.
Prevention Tip: Insulate pipes in vulnerable areas using pipe sleeves or heat tape. During cold nights, keep cabinet doors open and allow faucets to drip slightly to relieve pressure.

2. Clogged Main Sewer Line
Tree roots, grease buildup, or heavy rain can clog the main sewer line, causing sewage backups in tubs, sinks, or even the basement.
Prevention Tip: Never flush wipes or pour grease down the drain. Have your sewer line inspected with a camera every few years—especially in older Seattle neighborhoods with large trees.
🛠️ Pro tip: Use backwater valves to prevent raw sewage from backing up into your home during storms.
3. Overflowing Toilets
Whether it’s a blockage or a faulty float mechanism, an overflowing toilet is one of the most stressful plumbing emergencies.
Prevention Tip: Don’t use your toilet like a trash can. Flush only toilet paper. If it starts to overflow, shut off the water valve at the base of the toilet immediately.
🚽 If overflows happen often, you might need drain snaking or hydro jetting from a Seattle plumbing expert.
4. Water Heater Failure
Seattle homes often rely on traditional tank water heaters, which can leak, rupture, or fail unexpectedly, leaving you without hot water or flooding the area.
Prevention Tip: Flush your tank annually to remove sediment. Check for signs of rust or moisture around the base. Replace your unit every 8–12 years.

5. Leaking Faucets or Fixtures
A dripping faucet may seem minor, but over time, it leads to water waste and inflated bills. Leaks can also hide mold and wood rot.
Prevention Tip: Fix leaks promptly. Replace worn washers or cartridges. Upgrade to WaterSense-certified fixtures to save water and money.
💡 The EPA estimates that fixing household leaks can save 10% on your water bill each month.
6. Blocked Kitchen Sink
Clogs caused by grease, food scraps, or soap scum are extremely common in Seattle homes—especially after hosting guests or during the holidays.
Prevention Tip: Use a drain strainer and never pour grease or coffee grounds down the sink. Pour boiling water and baking soda regularly to help clear build-up.

7. Running Toilets
A continuously running toilet can waste hundreds of gallons of water per day—and drive up your Seattle Public Utilities bill fast.
Prevention Tip: Replace faulty flappers, adjust the float arm, or inspect the fill valve. These repairs are usually inexpensive and simple to DIY.
8. Frozen Outdoor Hose Bibs
Unprotected hose bibs are among the first fixtures to freeze in Seattle’s winter cold spells, often cracking and leaking into basements or crawlspaces.
Prevention Tip: Disconnect hoses in the fall, install insulated covers, or upgrade to a frost-free hose bib.
9. Low Water Pressure
Caused by sediment build-up, pipe corrosion, or municipal water line issues, low water pressure can be a frustrating issue that affects daily use.
Prevention Tip: Clean faucet aerators regularly. If the problem is throughout the house, call a plumber to inspect for blockages or leaks.
🧪 Consider a water quality test. Seattle’s soft water sometimes causes corrosion in older galvanized pipes.
10. Sump Pump Failure
For homes with basements, a failing sump pump during heavy Seattle rains can lead to flooding, mold, and damage to foundations.
Prevention Tip: Test your sump pump regularly by pouring water into the pit. Consider a battery backup for power outages.

Plumbing emergencies in Seattle aren’t just inconvenient—they can be devastating if ignored or mishandled. The good news? Most of them are 100% preventable with regular maintenance and timely repairs.
