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:

  1. Start with cold taps—open faucets and flush toilets.
  2. 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.

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.
