A pipe burst — how to stop the water and limit the damage

This article is for educational purposes only and is not a substitute for professional advice. Local codes, regulations, and best practices vary by region.

A pipe has burst and water is spraying everywhere or flowing steadily or filling the basement. This is a full emergency that needs immediate action. The first priority is stopping the water. The second is documenting damage for insurance. Everything else comes after you’ve turned off the water and called the plumber.

This is genuinely serious. Every minute the water runs, damage spreads. But a burst pipe is manageable with quick action. You have minutes—not hours—to respond. Here’s what to do.

Step One: Shut Off the Water

Immediately find your main water shutoff. This is usually near the water meter or where the main line enters your house. You already know where it is because you found it before there was an emergency, right? If not, find it now. Look in the basement, garage, or utility area. It’s a valve you can turn or a lever you can switch.

Turn it off. Turn the valve clockwise or flip the lever perpendicular to the pipe. You’re cutting off water flow to your entire house. If you can’t find the shutoff, the valve is stuck, or you’re unsure, locate a neighbor’s shutoff for reference or call the water utility’s emergency number and they can shut water off at the street meter.

This single action stops the problem immediately. Yes, you lose water to the house, but you stop new water damage from happening.

Step Two: Turn Off the Water Heater

If your water heater uses gas, turn it off at the thermostat or switch. If it’s electric, flip the breaker off. If water got to the heater, heat is still building pressure. Turning it off prevents additional damage or safety issues.

Step Three: Get People Away From the Water

This is especially important if water is near electrical outlets or your main electrical panel. Wet electrical systems are dangerous. If water is potentially near live electrical components, turn off the main breaker as well. Safety first.

Step Four: Call a Plumber

Call an emergency plumber immediately. Tell them you have a burst pipe and you’ve shut off the main water. This is the most urgent call you can make. Emergency plumbers respond quickly to burst pipes because damage spreads rapidly.

If you don’t know an emergency plumber, call your local water utility. They often have recommended plumbers on call. Or call a general contractor who can recommend one. Many plumbers answer emergency calls 24/7.

Expect to pay premium rates—emergency plumber calls typically cost $500-2,000 for service plus repair costs. This is worth the money. Delaying plumber service costs more in water damage.

Step Five: Document the Damage

Take photos of the water, the leak source, and affected areas. This helps with insurance claims. Note the time the water started and when you shut it off. Write down the plumber’s name and when they’re arriving.

Which Pipe Burst?

Try to identify where the burst is. If you can find water running out somewhere (inside the wall, in the ceiling, under the floor), that’s where the plumber will start looking. Tell the plumber exactly where you see water.

The burst might be on a supply line (carrying pressurized water), in which case water sprays everywhere. Or it might be on a drain line, in which case water flows but doesn’t spray. Drain line bursts are less critical but still need repair.

What the Plumber Will Do

The plumber will locate the burst, assess whether the pipe can be patched or must be replaced, and make repairs. Most burst pipes require replacement of the damaged section. Simple replacements take a few hours. Complex bursts (in walls or under concrete) take longer and cost more.

Cost ranges from $500 to $5,000+ depending on pipe location and extent of damage. If the burst is in an accessible area (basement, crawlspace), it’s cheaper. If it’s inside a wall or under flooring, access is harder and cost increases.

For water damage (wet drywall, flooring, insulation), you’ll need separate restoration services. This is where a water damage company comes in (as covered in the flooding article). They extract water, dry structures, and prevent mold. This costs $1,000-5,000+ depending on damage extent.

Temporary Measures

Once the main water is off, water damage slows dramatically. You can begin damage control. Mop up standing water. Move furniture and belongings away from wet areas. Remove saturated materials if they’re not load-bearing (you can remove wet carpet, but not drywall supporting a ceiling).

Open windows and doors for ventilation if weather allows. Run fans to move air and start drying. This doesn’t replace professional drying but helps initially.

If water is still running (from a drain or slowly from somewhere), place buckets or towels to contain it until the plumber arrives.

Insurance and Restoration

Contact your homeowner’s insurance immediately. Most policies cover burst pipes as part of water damage coverage. Document everything with photos. Keep receipts for any repairs or restoration.

Insurance companies often recommend or require specific contractors. Let them guide the restoration process. Claim adjusters might need to inspect damage before cleanup begins, so don’t remove saturated materials until they’ve assessed.

Secondary Damage Prevention

Shut off the water heater to prevent additional pressure and damage. If electricity is near the burst area, consider turning off relevant breakers until the area dries completely. Wet electrical components are hazardous.

If the burst is in a freezing area (exposed pipe), you might need temporary protection or heat to prevent it refreezing while you wait for repairs. The plumber will handle this.

After Repair

Once the plumber repairs the pipe, water is back on. Check for leaks at the repair site. If water still drips or sprays, the repair isn’t holding and you need the plumber back.

Turn the water heater back on (or flip the breaker) once you’re sure the house is dry and the repair is solid.

Restoration Timeline

Complete water damage restoration takes weeks. Structures need to dry completely before repairs (drywall replacement, flooring, etc.). Dehumidifiers and air movers run continuously for days. Mold prevention is critical during this period.

Keep records of all professional work and costs. These become deductible expenses on your insurance claim.

The Bottom Line

A burst pipe is a genuine emergency. Your immediate action is shutting off water and calling a plumber. Every minute matters. Once water is stopped, damage is contained. A plumber will locate and repair the burst. A water damage company will handle restoration. These professional services are expensive but critical. The alternative—leaving water running—causes exponentially worse damage. Quick action turns a burst pipe into an expensive repair. Delayed action turns it into a disaster.
