First Signs of a Burst Pipe
Before water floods a room, pipes often give warning signs:
- Sudden drop in water pressure
- Unexplained puddles or damp spots on walls/floors
- Sounds of running water behind walls
- Discolored water or rusty discharge from faucets
If you detect any of these warning signs, act fast to prevent further damage.
Step 1: Shut Off the Main Water Supply Immediately
The first and most critical step is to locate and shut off the main water valve. In Portland homes, it’s typically:
- Inside the basement or utility area
- In crawl spaces
- Outside near the foundation or water meter box
Turning off the main water supply prevents additional flooding. If you’re unsure where your shut-off valve is located, check our Einstein Pros Emergency Plumbing Page for a diagram and instructions.
Step 2: Drain the Remaining Water
Once the water is shut off:
- Start with cold taps—open faucets and flush toilets.
- Then run hot water lines to fully depressurize your piping system.
This step helps reduce pressure in the pipe and limits further leakage.
Step 3: Contain and Control the Leak
Use towels, buckets, or containers to capture water. If the burst pipe is visible:
- Wrap it with heavy-duty tape or a pipe repair clamp as a temporary fix.
- Avoid chemical sealants, as they may worsen the pipe damage.
IMPORTANT: These measures are temporary. Permanent repairs must be done by licensed professionals to maintain safety and code compliance.
Step 4: Shut Off Electricity If Water Is Near Outlets
If flooding has reached outlets, appliances, or the electrical panel:
- Go to your breaker panel
- Shut off the affected circuits or entire home power if needed
This prevents electrical shock hazards. Safety must be your top priority during plumbing emergencies.
Step 5: Document and Protect Your Property
Take photos and video of the affected area before disturbing anything. This documentation is essential for insurance claims.
Protect key areas:
- Remove valuables from the floor
- Lift furniture using blocks or foil
- Increase ventilation with fans or heaters (do not use gas heaters without supervision)
Step 6: Mitigate Mold and Water Damage Immediately
Water left for over 24–48 hours can lead to mold growth. Steps to mitigate damage:
- Use fans and dehumidifiers
- Keep interior doors open for airflow
- Remove soaked carpeting or padding if heavily saturated
The Environmental Protection Agency (EPA) recommends drying all surfaces within 24–48 hours to prevent mold colonization.
Step 7: Apply a Temporary Pipe Repair (If Safe)
If the burst area is accessible and conditions are safe:
- Use a pipe repair clamp, epoxy putty, or rubber patch with hose clamps
- Never use open flame tools or heat guns during emergency repairs
These are short-term measures until professional repair or replacement is completed.
Portland Winter Prevention Checklist (Print & Post Near Your Water Shut-Off)
| Task | Recommended Timing |
|---|---|
| Insulate exposed pipes | Early November |
| Seal cracks in crawl spaces or exterior walls | Before first freeze |
| Know the location of your main shut-off valve | Immediately |
| Schedule winter plumbing inspection | Late Fall |
| Keep thermostat at 55°F+ (even when away) | All winter |
How to Prevent Future Burst Pipes
Prevention is just as important as emergency response. In Portland’s freeze-thaw winters:
1. Insulate Pipes: Use foam insulation on pipes in basements, crawl spaces, garages, and exterior walls.
2. Seal Leaks & Drafts: Cold air entering through cracks can freeze pipes.
3. Maintain Steady Indoor Heat: Never let indoor temps fall below 55°F, even when traveling.
4. Let Faucets Drip During Freezes: Keeping water moving can prevent freezing.
