Burst Pipe? What to Do Before the Plumber Arrives

A burst pipe is one of the most stressful plumbing emergencies a homeowner can face. One minute everything is fine. The next, water is pouring into your home, soaking floors, walls, and belongings. Your heart rate spikes, and the first thought is usually the same: How do I stop this before it gets worse?

The good news is this: what you do in the first few minutes matters more than you think. Taking the right steps before the plumber arrives can dramatically reduce damage, cleanup costs, and repair time.

Here’s exactly what to do if a pipe bursts in your home.

Step 1: Shut Off the Water Immediately

This is the most important step. If water is still flowing, damage is still happening.

Locate your main water shut-off valve and turn it off right away. In most homes, it’s near the water meter, in the garage, outside near the foundation, or in a utility area. Turn the valve clockwise until it stops.

If the burst pipe is connected to a specific fixture—like a toilet, sink, or washing machine—you may be able to shut off the local valve instead. But if you’re unsure, shut off the main supply. It’s always safer.

If you don’t know where your shut-off valve is, this emergency will teach you why it’s critical to find it now.

Step 2: Turn Off the Water Heater

After shutting off the water, turn off your water heater. This prevents pressure buildup and protects the unit from damage.

For electric water heaters, switch off the breaker. For gas units, turn the control to the “off” position. This step is especially important if hot water pipes are involved in the burst.

Step 3: Relieve Pressure in the System

Open all faucets in your home—both hot and cold—to drain remaining water from the pipes. Start with the lowest fixtures first, like outdoor spigots or basement sinks, then work upward.

This reduces pressure in the system and helps minimize continued leaking from the damaged pipe.

Step 4: Contain the Water

Now focus on limiting the spread of water.

Use towels, buckets, or pans to catch dripping water. If possible, place a container directly under the burst section. A wet/dry vacuum can be extremely helpful for removing standing water quickly.

Move furniture, electronics, rugs, and valuables out of the affected area. Water damage spreads fast, and the quicker you act, the more you save.

If water is near electrical outlets or appliances, do not touch them. If it’s safe to do so, turn off electricity to the affected area at the breaker panel.

Step 5: Apply a Temporary Patch (If Safe)

This is optional and only meant to reduce active leaking—not fix the problem.

If the pipe is accessible and you can safely reach it, you can temporarily wrap the damaged section with a thick cloth, rubber patch, or plumber’s tape. Even duct tape can slow the flow enough to limit damage.

Do not attempt major repairs or cut into pipes. Temporary containment is enough until a licensed plumber arrives.

Step 6: Avoid DIY Fixes That Can Make Things Worse

In the middle of a plumbing emergency, it’s tempting to take drastic action. This is where many homeowners make costly mistakes.

Avoid using sealants, chemical products, or attempting pipe replacements on your own. Improper fixes often fail under pressure and can lead to bigger breaks, flooding, or code violations.

Your goal is damage control, not permanent repair.

Common Causes of Burst Pipes

Understanding why pipes burst helps prevent it from happening again. The most common causes include:

• Aging or corroded pipes
• High water pressure
• Temperature fluctuations
• Poor installation or weak joints
• Undetected leaks that worsen over time

In older homes, pipes may simply reach the end of their lifespan. In others, a small leak slowly weakens the pipe until it fails suddenly.

Why Speed Matters

The longer water flows unchecked, the more damage occurs. Water seeps into drywall, flooring, insulation, and framing. This can lead to mold growth, structural damage, and expensive restoration work.

Many burst pipe disasters could have been half as costly if water was shut off within the first few minutes. Fast action protects your home—and your wallet.
