Burst pipe? What to do in the first hour
Shut the main first. Everything else in water damage is downstream of how fast you stop the water. Then follow the steps below, in order. If water has already been sitting more than two days, start with the water damage and mold remediation guide instead.
Quick answer
Turn off the main water valve, then cut power to any wet area from the breaker, not from inside standing water. Get the water out with a wet vac, pull carpet pad and anything soft, and photograph everything before you move it. Air movers and a dehumidifier need to be running within a few hours; mold starts in 24 to 48.

1The first 15 minutes
- Shut the main. Clockwise until it stops. If it will not turn, go to the curb stop; see chapter 2. Water keeps coming at full pressure until this is done, and a half-inch supply line moves several gallons a minute.
- Kill power to the wet area at the panel. Never walk through standing water to reach an outlet or the panel itself; if the panel is in the wet area, leave it and call your utility.
- Open the lowest faucet in the house and a high one too. That drains the lines and drops the pressure behind the break, so the leak slows to a trickle while you work.
- Photograph everything before you move it. Wide shots of each room, close shots of the break and of anything damaged. This is the evidence your adjuster asks for, and it settles disputes later.
- Get standing water out. Wet vac, pump, mop, towels. Speed matters more than technique in the first hour. Pull carpet pad, area rugs and cardboard; pad is almost never worth saving.
- Start drying. Fans plus a dehumidifier, doors and cabinet doors open, running continuously. A fan alone in a closed room moves humid air around and dries nothing.
How long the rest takes depends on what got wet; the drying timeline after flooding walks through it material by material.
2Finding your shutoff
Most Oklahoma homes have the main valve where the supply line enters the house: a garage wall, a utility closet, or just inside a crawlspace hatch. Slab homes often put it in the front yard in a plastic box near the meter. Find it now, before you need it, and hang a tag on it.
Main valve
Gate or ball valve on the house side of the meter. A gate valve turns clockwise several times; a ball valve is off when the handle sits across the pipe.
Curb stop
In the meter box at the street, under a metal or plastic lid. It needs a meter key or a long wrench; your water utility can shut it if you cannot.
Water heater
If the break is on the hot side, the cold inlet valve on top of the tank stops it without shutting the whole house. Turn the heater off too, so it does not fire on an empty tank.
A gate valve that has not been turned in years may not seal, or may shear its stem. If it spins freely or will not move, do not force it; go to the curb stop.
3Frozen pipes in Oklahoma
Ice storms, not steady cold, burst Oklahoma pipes. A line in an exterior wall, an attic, or an unheated crawlspace freezes during a two- or three-day event, and the break shows up when it thaws, often while the house is still empty. Water expands about nine percent when it freezes, and the pressure builds between the ice plug and a closed faucet, which is why the split is usually a foot or more from where the ice actually was.
Where lines freeze first
Hose bibs and the pipe behind them, supply lines in a north-facing exterior wall, lines running through a garage or over an unheated crawlspace, and anything in an attic. Pre-1980 homes with original galvanised supply and no pipe insulation fail first.
If a pipe is frozen but has not burst
Shut the main, open the faucet on that line, and warm the pipe slowly from the faucet end back toward the ice with a hair dryer or warm towels. Never use an open flame. If the line splits when it thaws, the main is already off and the damage is a few gallons, not a few hundred.
If you come home to a thawed break
Treat it as a two-day-old leak, because it may be. Go straight to the three-tier test in chapter 5; water that sat while you were away has almost certainly reached a wall cavity.
Call and a remediator can meter the cavity and tell you what has to come out, and what can stay.
5Dry it yourself, or call?
The dividing line is not how much water there was. It is what the water touched and how long it sat.
Clean supply water, caught within hours, on tile, vinyl or sealed concrete, in one room. Fans and a dehumidifier running for three to five days, and a moisture check at the end.
Water that reached a wall cavity, got under cabinets or a tub, soaked a subfloor, or covers more area than one household dehumidifier can keep up with. Commercial air movers exist because household units cannot pull enough water per hour to beat growth.
Water that sat more than two days, a ceiling that is sagging, hardwood that is cupping, or any break on a drain or sewer line. That last one is a contamination question, not a drying one; read sewage backup safety first.
Whichever tier you are in, the test at the end is the same: framing and subfloor read dry on a meter against a dry reference in the same house. Dry to the touch is not dry.
6Insurance and documentation
Most homeowner policies cover a burst pipe as a sudden and accidental loss. They do not cover a slow leak you should have noticed, and many exclude damage from a pipe that froze because the heat was off. Two things decide how the claim goes: how fast you mitigated, and how well you documented.
| Do this | Why it matters |
|---|---|
| Call the claim in the same day | Policies require prompt notice; waiting a week invites a denial |
| Photograph before cleanup, and keep the broken pipe section | The adjuster needs to see cause and extent; the fitting is the proof |
| Start drying without waiting for the adjuster | You are required to prevent further damage; mold growth from delay is on you, not the policy |
| Keep every receipt: fans, dehumidifier rental, towels, hotel | Mitigation costs are usually reimbursable |
| Ask the drying crew for moisture logs at start and finish | Logs prove the structure was dried, which heads off a mold dispute later |

7Preventing the next one
Most burst pipes in Oklahoma are one of four things, and all four are cheap to prevent.
- Rubber washing machine hoses. Replace them with braided stainless. They are the single most common indoor flood source, and they fail without warning at full pressure.
- Uninsulated lines in exterior walls, attics and crawlspaces. Foam sleeves on every exposed run; a sealed crawlspace vapor barrier keeps the crawlspace warmer and drier at the same time.
- Hose bibs left connected through an ice storm. Disconnect hoses in November. Frost-free bibs still burst if a hose stays on.
- Nobody knows where the shutoff is. Find it, tag it, and show everyone in the house. During an ice storm warning, let the farthest faucet drip and open the cabinet doors under sinks on exterior walls.
A leak-detection shutoff valve on the main closes the water automatically when flow runs continuously for longer than any normal use. For a house that sits empty during the week, it is the one upgrade that turns a burst pipe into a puddle.
When to call a pro
A small, clean, fast-caught leak on a hard floor is yours to dry. Once water has sat, reached a wall cavity, soaked a subfloor, or came from a drain, a crew with containment, commercial drying and a meter is cheaper than doing it twice. The water damage and mold remediation guide shows what a proper job includes, and the city pages above connect you with one near you.
8FAQ
Will a frozen pipe always burst?
No. Many freeze and thaw without splitting, especially copper and PEX with room to expand. The risk is highest when ice forms between a closed faucet and the plug, because the pressure has nowhere to go. Opening the faucet on a frozen line removes most of that risk.
Does homeowners insurance cover a burst pipe?
Usually yes, as a sudden and accidental loss, including the water damage it causes. The pipe repair itself is often excluded, and so is damage from a slow leak or from a pipe that froze while the heat was off. Call the claim in the same day and document everything.
How long does drying take after a burst pipe?
Three to five days for a clean, fast-caught leak on hard flooring with proper airflow. A week or more when framing, insulation or subfloor got wet. The finish line is a moisture reading at the dry reference, not a dry surface.
Can I turn the water back on to find the break?
Only briefly, with someone watching the suspected area, and only after you know where the main is. Better: leave it off, open the faucets, and look for the wet spot. A crew with a thermal camera finds a hidden break without water running.
Who do I call first, a plumber or a restoration crew?
The plumber fixes the pipe; the restoration crew dries the house. If the water is off and the damage is one room, a plumber first. If water reached walls or sat for a day, call both; the drying cannot wait for the repair.
