What to do when a pipe bursts: the first few minutes
A split pipe can move a surprising amount of water. The order of your first moves matters more than speed on any single one.
Work through these in order
Your first goal is to stop the flow. Your second is to remove electrical risk. Your third is to limit damage. Cleanup and repairs come after all three.
If you do not know where the main valve is, read how to shut off main water valve in your house now, then come back. A burst is a poor moment to start looking for it. If the spray is heavy or the ceiling is bulging with water, stop reading and call our emergency plumber line, which is open 24/7.
Close the main shutoff
Turn a gate valve clockwise until it stops, or a quarter turn for a lever. Water stops at the house.
Cut power where water is falling
If water is near outlets, a panel or a ceiling fixture, switch off that breaker. Do not stand in water to do it.
Open a low tap and a high tap
Draining the lines relieves pressure and pulls water away from the break.
Turn off the water heater
Switch the gas control to pilot or the electric breaker off so it never fires with an empty tank.
Safety before cleanup
Water and electricity do not mix, and a ceiling full of water can fall without warning.
Hazards to respect
A ceiling that sags, bulges or drips from several spots may be holding a lot of water. Stay out from under it. Poking a small hole with a screwdriver can release a gush, so only do that with a bucket in place and a clear exit path, or leave it for the plumber.
If the water is rising near a power strip, a panel or an appliance cord, leave the room and shut the breaker only if you can reach it without stepping in water. If you cannot, call and tell the person who answers. If you smell gas at any point, follow the rules in signs of a gas leak in your house: leave first, then call from outside.
- Sagging ceilingStay clear; water pools in the gap above the drywall.
- Water near outlets or cordsDo not touch. Breaker off only if the floor beneath you is dry.
- Hot water sprayingA burst on a hot line can scald. Keep children and pets out.
- Slippery floorsWear shoes with grip and move slowly.
- Standing water in a garage or basementTreat it as live until the power is off.
Control the water and protect what you can
Once the main is closed, the pipe stops feeding the leak, but the water already out is still soaking in.
| Task | How to do it | Why it helps |
|---|---|---|
| Move small items | Lift rugs, boxes and electronics onto counters or furniture | Wet cardboard and fabric ruin quickly |
| Soak up standing water | Use towels, a mop or a wet vacuum made for water | Less water reaches subfloor and baseboards |
| Catch ceiling drips | Set buckets under each drip and lay a tarp over furniture | Keeps drywall from collapsing onto belongings |
| Run fans and open windows | Aim airflow across wet areas, dehumidifier if you own one | Slows mold and swelling |
| Photograph everything | Take wide shots, close-ups and a short video before moving things | Gives your insurer a clear record |
| Keep the old pipe piece | Set aside the split section if you can reach it | A plumber can read how it failed |
Wet drywall, insulation and carpet padding start to grow mold in a couple of days when they stay damp. Drying fast matters, and so does honesty about what you cannot reach. If the wet area is large, the next step is a drying company, and the plumber fixes the pipe first so the water stops for good. See burst pipe repair for what the pipe fix involves.
Why pipes burst in Central Texas homes
Knowing the cause tells you whether the failure is a one-off or a warning about the rest of the system.
| Cause | How it happens | Where it tends to show |
|---|---|---|
| Freezing | Water expands as it turns to ice and can split the pipe wall, often when it thaws | Exposed lines in attics, garages, outside walls and hose bibs |
| High pressure | Pressure beyond what fixtures are built for strains joints and hoses | Washer hoses, water heater connections, toilet supply lines |
| Corrosion | Metal thins from the inside until it pinholes or splits | Older steel and copper; see [[/guides/signs-of-corroded-pipes/|signs of corroded pipes]] |
| Ground movement | Clay soils that swell and shrink can stress buried lines and slab penetrations | Yard lines and where pipe passes through a foundation |
| Poor joints | A badly soldered, glued or clamped joint lets go under load | Recent DIY or rushed repairs |
| Impact | A nail, an auger or a shovel strikes the pipe | Remodel work and digging |
A hard freeze now and then can catch exposed attic lines and hose bibs unprotected. The same pipes sit in heat for months, which can make plastic fittings brittle. Both swings leave a pipe weaker than it looks.
Burst pipe, pinhole or slow split? What each looks like
Not every failure is a spray. The type of break changes what to expect and how fast to move.
Three common patterns
A full burst sprays or pours and often has a loud bang or a sudden drop in pressure. A split along the seam leaks more gently, with steady dripping that wets a wall over hours. A pinhole is the quietest: a fine jet, a damp spot, or a greenish crust at the surface.
All three need the water off. A pinhole in one spot is often a sign that other spots on the same line are close behind, so ask the plumber to look at the condition of the whole run. When several pinholes show up, repiping may be the better long-term answer than repeated patches.
| Type | Signs | Urgency |
|---|---|---|
| Full burst | Spray, loud bang, sudden pressure loss, flooding | Close the main now |
| Split seam | Steady drip, growing stain, damp insulation | Close the main or fixture valve and call |
| Pinhole | Fine mist, green crust, small damp spot | Close the fixture valve; call the same day |
| Joint failure | Drips at a coupling or fitting | Close the valve and call |
What a plumber does after the water is off
The visit follows a predictable path. Knowing it lets you give useful information on the phone.
Find the break
The plumber traces the wet area back to the failed section, sometimes with a moisture meter or a line locator.
Test the line
Pressure is checked on the rest of the run to find other weak spots before they fail.
Cut out and replace
A damaged section is removed and new pipe and fittings go in. The repair method depends on the pipe material.
Restore and recheck
Water comes back on slowly, the repair is watched under pressure, and you are told what to look for over the next days.
Tell the person who answers where the water came from, what the pipe is made of if you know, and what you already shut off. For a buried or under-slab break, the same questions apply, and the water line repair and slab leak repair pages explain how those jobs differ from a wall repair.
What affects the bill, and a word on insurance
People ask two things right after a burst: what will the repair cost and will my policy help.
Cost drivers and claim basics
The repair price depends on how easy the pipe is to reach, how much pipe is damaged, what it is made of, and how much cleanup is part of the job. A visible section under a sink is one kind of job. A break in a finished wall or under concrete is another. Ask about pricing when you call.
For a claim, take photos before you clean, keep receipts for any emergency purchases, and read your policy for how it treats sudden versus gradual damage. We cannot say what your policy covers. Our general guide, does homeowners insurance cover plumbing leaks and burst pipes, lists the questions to put to your insurer.
- Pipe material and sizeCopper, PEX, steel and plastic repair differently.
- Access to the breakOpen framing is easier than a finished wall.
- Length of damaged pipeOne section or a whole run.
- Where the pipe runsAttic, wall, yard and slab lines call for different methods.
- Cleanup neededDrying and patching are separate from the pipe work.
Reduce the odds of another burst
Most bursts have a cause you can change.
Insulate exposed pipes
Foam sleeves on attic, garage and outside-wall lines cost little and are worth adding before a cold snap.
Cover hose bibs
Disconnect hoses in the fall and fit insulated covers when a hard freeze is forecast.
Check pressure
A gauge on a hose bib reads it. If it is high, ask about a regulator. See [[/low-water-pressure/|low water pressure]] for the other end of the problem.
Replace old supply hoses
Braided stainless hoses outlast rubber ones. Date them when fitted.
Learn your shutoffs
Teach everyone where the main and the fixture valves are. Test them once a year so they do not seize.
If you will be away during a hard freeze, closing the main and draining the lines is the surest protection. Dripping a tap helps only in some cases and is not a substitute. A plumber can tell you what suits your layout, and pipe repair is the next stop if a line has already been damaged.
When to call a plumber right now

What to do when a pipe bursts and I am not home?
If you have a smart valve or a neighbor with a key, close the main from there. Otherwise, go home and shut off the water first, then call. Do not enter a flooded area if you suspect live outlets. Our emergency plumber line answers 24/7.
Should I turn off the electricity after a burst?
Only if you can reach the breaker without standing in water. If outlets, a panel or light fixtures are wet, stay away and tell the person you call. Never touch a device that is in water.
How do I know the main valve is really closed?
Open a low tap, such as a hose bib. If water keeps running for more than a short while, the valve is not closed all the way. Check the meter dial too. If it moves, water is still passing.
What should I do about water in the ceiling?
Stay out from under it, set buckets below the drips and call. A bulging ceiling can hold a lot of water and give way suddenly. Do not puncture it unless you have a bucket in place and a clear exit.
How fast does mold start after a burst?
Mold can begin growing within a couple of days when materials stay wet. Remove standing water, run fans and open windows. Wet carpet padding and drywall may need to come out if drying is slow.
Can I fix a burst pipe myself?
A temporary clamp or push-fit coupling can hold a clean, accessible split until the plumber arrives. Do not use tape or putty as a permanent fix. Corroded or buried pipe needs a plumber. See burst pipe repair.
How much does it cost to fix a burst pipe?
It depends on access, pipe type, how much pipe is damaged and how much cleanup the job includes. Ask about pricing when you call and describe where the water came from.
Will my insurance pay for a burst pipe?
That depends on your policy, which we cannot read for you. Photograph the damage, keep receipts and call your insurer. See the general insurance guide.
Why did my pipe burst when it did not freeze?
High pressure, a corroded wall, a bad joint or shifting ground can all do it. A plumber can test pressure and look at the pipe to find which cause fits your house.
Is a burst pipe a same-day job?
Same-day service is available, and calls are answered 24/7. Tell the person on the phone what you have shut off so they can plan the visit.
