What to do when a pipe bursts: six steps in order
The first minutes matter most.
The first minutes decide how much damage you get. Do these in order, and stop at any step where your safety is at risk.
Stay calm and look for danger
If water is near outlets, a panel or a plugged-in appliance, keep away from it.
Shut off the main water valve
Turn it clockwise until it stops. This one action ends the flow for most breaks.
Cut power if water reaches electrics
Only from a dry spot, and only if the panel is not itself wet. Otherwise call for help.
Open the lowest cold tap
Draining the lines relieves pressure and lets standing water leave the broken section.
Switch off the water heater
Cut its power or set gas to off so it does not run on a drained system.
Call a plumber
Someone picks up day or night. Say where the water is and whether it has stopped.
Why the main valve comes first
A supply pipe sits under pressure all day, so a break keeps pushing water until you close the valve upstream of it. Even a small split can release a lot of water in an hour, and a full break can soak a floor in minutes. Locating the valve before an emergency is the best preparation you can make. Unsure where yours is? Read how to shut off your main water valve tonight, long before any flood.
Most homes have the main near where the line enters the house, often in a garage, a utility room, a crawlspace or a basement, and sometimes at a meter box outside. Condos and apartments may have a unit shutoff and a building shutoff. If your valve is stuck or the break is before it, the meter box near the street is the next stop.
Causes of a burst pipe and what a cold snap can do
Most bursts have a history.
Every burst has a cause. Knowing the likely ones helps you decide how worried to be and what to do about the rest of the plumbing.
Why pipes burst
Freezing is the classic cause. Winters near Puget Sound are mild, but a cold snap can freeze supply lines in a garage, a crawlspace, an exterior wall or an outdoor hose bib, and ice expansion splits the pipe. The water does not usually pour out while frozen. The trouble starts when the ice thaws and pressure reaches the crack.
Other causes are quieter. Old galvanized pipe corrodes from inside until a thin wall gives way. A pipe rubbing on a joist wears through over the years. A water hammer slam from a quick-closing valve stresses fittings. A fitting installed badly years ago can let go at last. Roots and shifting soil can crush a buried line. If pipes in your house are old, signs of corroded pipes shows what to look for before one fails.
| Cause | Where it tends to strike | Warning before it fails |
|---|---|---|
| Freezing | Garage, crawlspace, exterior walls, hose bibs | Frost on pipes, a tap that gives only a dribble in cold weather |
| Corrosion | Old galvanized or thin copper | Brown water, pinhole weeps, green crust |
| Water hammer | Fittings near fast valves | Banging when a tap or washer shuts off |
| Rubbing and wear | Where pipe touches framing | Damp spots on a joist |
| Soil movement or roots | Buried service or yard lines | Wet ground, a drop in pressure |
| Bad joint or fitting | Past repairs, push-fit or glued joints | A slow drip at a union |
What a cold snap really threatens
The risk is lines that run through unheated spaces and lines on outside walls. Disconnect garden hoses before cold weather, wrap exposed pipe, and keep garage doors shut during the coldest nights. Leave cabinet doors open beneath sinks on outside walls so warm air reaches the pipes, and keep one far tap running a thin stream during a hard night.
The full routine is in how to protect pipes from a hard freeze. A pipe that is frozen but intact can be thawed slowly with a hair dryer or warm towels. Never use an open flame. If a tap shows no flow in cold weather, assume a frozen line and treat it as one.
The first hour and your paper trail
Limit the harm and record the facts.
Once the water is off, the clock shifts. Now you are limiting the harm from what already spilled, and gathering what you need for the repair.
The first hour after the shutoff
Move furniture, rugs and anything valuable away from the wet area. Lift items off the floor onto blocks or foil. Use towels, mops and a wet vac to pull up standing water, starting with the lowest point. Pull up soaked rugs, since the pad underneath holds water and sours quickly. Open windows and run fans where it is safe to do so.
Check the ceiling below any burst on an upper floor. A bulge or sag means water is pooled above. Put a bucket under the lowest point, stand clear, and puncture the bulge there with a screwdriver so the water drains in a controlled way. That relieves the weight before the ceiling gives way.

- Move valuables up and outElectronics, paper, rugs and anything that wicks water
- Soak up standing waterTowels, mops and a wet vac, lowest spot first
- Run fans and open windowsMoving air starts the drying early
- Relieve a bulging ceilingPuncture at the low point, bucket underneath
Documenting for your insurer
Before cleaning, shoot photos and a short video, hold on to ruined items until told otherwise, and jot down the time the water began and the time you stopped it. Read your own policy, then phone your insurer and ask how a claim works. Your insurer, not this page, can say what a policy covers.
Keep receipts for fans, wet vac rentals and emergency work. Ask the plumber to note the cause and location of the break on any paperwork, since the claim is easier to follow with a clear description. Renters should tell the landlord at once and also check their own renter’s policy.

Where the water shows and who to tell
Rooms, yards and shared buildings differ.
Not every burst is an indoor supply line. Where the water shows up changes what you shut off and who may need to be involved.
Burst pipes by location
A burst in an upstairs wall sends water down through the ceiling below. A burst in a crawlspace may run unseen for hours, and the first sign is often a drop in pressure or the sound of a pump or meter running. A hose bib that splits outdoors can empty into a wall cavity. A buried line in the yard shows up as a soggy patch, a sink hole or a pool with no rain behind it.
Each calls for a different search. If you hear water but see none, the how to find a water leak in your house guide walks through a meter test, and leak detection finds hidden leaks with listening gear. A suspected break in a pipe buried under concrete may be a slab leak, covered in signs of a slab leak.
| Where water shows | Likely source | First action |
|---|---|---|
| Ceiling stain or drip | Pipe in the floor above | Main off, bucket, relieve a bulge |
| Wet wall, warm to touch | Hot line in the wall | Main off, water heater off |
| Floor damp with no source in sight | Line under the floor or slab | Main off, meter test |
| Soggy yard with no rain | Buried service or irrigation line | Main off at the meter |
| Spray from an outdoor spigot | Split hose bib | Close the interior shutoff for that line |
| Meter spinning with all taps closed | Leak somewhere on the property | Main off, call |
Apartments, condos and townhomes
In a multifamily building, the break may be in your unit, in a neighbor’s, or in a shared stack. Shut your unit’s valve, then tell the property manager or the HOA right away. Water travels down through floors, so move quickly and warn neighbors below. Many associations have rules about who pays for what, so ask before work starts.
Renters should photograph the damage and notify the landlord in writing. A burst in a rental is not something to fix alone, since the owner usually chooses the repair company. If water is threatening your belongings, protect them first and report second.
Water and electricity
If water has reached outlets, a breaker panel or a ceiling light fixture, do not touch switches or step into standing water. Stay dry, leave the area and call for help. If the panel is wet, call the electric utility or 911 from outside.What the visit covers and what moves the price
From finding the break to pressure testing.
A plumber does more than patch the hole. The visit usually follows a sequence, and knowing it helps you ask the right questions.
What the repair visit covers
The plumber confirms the water is off, finds the break, and decides whether a short section can be cut out and replaced or the pipe is worn along its length. A frozen split in a young copper line is usually a simple sleeve or section replacement. A burst in old galvanized or thin copper may be a hint that more failures wait nearby.
Expect pressure tests after the fix, a look at the nearby pipe and fittings, and advice on whether a bigger job such as repiping is worth considering. The burst pipe repair page describes the work, and pipe repair covers lesser breaks. For an after-hours call, the emergency plumber page explains how the line works.
| Step | What happens |
|---|---|
| Confirm shutoff | Main closed and the area made safe |
| Locate the break | Open a wall or floor only where needed |
| Cut out the damage | Remove the split section back to sound pipe |
| Install new pipe | Matching material and secure fittings |
| Pressure test | Check for leaks before closing up |
| Look at the rest | Assess nearby pipe, valves and supports |
What drives the cost, with no numbers
Access matters most: a burst in an open crawlspace is simpler than one behind tile. The pipe material, the length of damaged pipe, whether drywall needs opening, and whether an after-hours call was needed all move the total. Water damage cleanup is separate from the plumbing repair, and drying and rebuilding are different trades.
Pricing depends on those factors, so raise it during the call and say where the water is and how old the plumbing is. After more than one break in the same house, ask whether the pipe is nearing the end of its life.
Preparing before a pipe lets go
Small habits cut the damage later.
The best response is the one you rehearse. A few small steps make the next incident far less costly.
Prepare before a pipe lets go
Test your main valve twice a year, since valves that sit unused can seize. Learn where the heater shutoff is. Label the breaker for the water heater. Keep a flashlight, towels and a bucket in one spot. If a hose bib has no shutoff, ask a plumber to add one inside the house.
Replace braided washer hoses and old supply lines on a schedule. An automatic leak sensor under the sink and near the water heater costs little and sends a phone alert. Know the signs of failing pipe, and call about them before they fail. Pressure that has changed lately may be a clue, as explained in why is my water pressure low.
- Exercise the main valveClose and reopen it twice a year
- Know the heater shutoffsCold inlet valve and the power or gas control
- Insulate exposed pipeGarage, crawlspace and exterior wall runs
- Replace aging supply hosesWasher and toilet lines are common failure points
- Fit leak sensorsUnder sinks and beside the water heater
- Keep an emergency kitFlashlight, towels, bucket and the plumber’s number
When a burst pipe needs a call now
Phone the moment you see any of these, even if you have already closed the valve.
Water still flowing after the main is shut
The break may be ahead of your valve, or the valve is not sealing.
Water near electrics
Keep dry and get help before anyone steps in.
A bulging or dripping ceiling
Trapped water can bring the ceiling down.
A drop in pressure with no visible leak
A hidden break may be running.
