A burst pipe is an emergency with a clock attached. Water can be running into a wall, under a floor, or through a ceiling while you are still working out what happened, and every minute of delay adds to what has to be replaced.
This is the order to do things in. If you do nothing else, do steps one and two.
The checklist
- Shut off the water at the main house valve. If you cannot find it or it will not turn, call the water utility. Knowing where this valve is before you need it is the single most valuable preparation you can make.
- If the break is on a fixture supply line, close the angle stop under the fixture first — it is faster and it isolates the leak.
- Cut power to affected rooms at the breaker, but only if you can reach the panel without walking through water. If the panel is in a wet area, leave it alone and call an electrician.
- Open the lowest faucet in the house, and open a faucet on an upper floor if you have one, to drain remaining water out of the lines and relieve pressure.
- For a frozen pipe that has not yet split, this is also where you warm it — gently, with a hair dryer, heat lamp, or towels. Never with an open flame.
- Photograph everything before you move it: the water on the floor, the water line on the wall, the failed pipe, and every affected room.
- Move furniture, electronics, rugs, and anything else you can out of the wet zone. Put foil or plastic under furniture legs you cannot lift.
- Extract standing water with towels and a wet vac on hard surfaces only.
- Start air movement and dehumidification, keeping the space closed if the outdoor air is humid.
- Call your insurance company to report the loss, and call for professional water removal if the water reached carpet, drywall, a ceiling, or a wall cavity.
If electrical systems or contaminated water are involved, prioritize personal safety and follow professional or emergency guidance.
If the pipe is frozen but has not burst yet
- Shut off the main first. If the pipe has already split inside a wall, thawing it will release water into the cavity.
- Open the nearest faucet so melting water has somewhere to go and the line has somewhere to relieve pressure.
- Warm the pipe gradually. A hair dryer on low, a heat lamp, or towels soaked in warm water all work. Work from the faucet end back toward the freeze.
- Never use a propane torch, a heat gun on high, or any open flame. These are a common cause of house fires in winter.
- Do not pour boiling water on a pipe or use a hammer to break up ice.
- If you cannot locate the frozen section or it is inside a wall, call a plumber rather than opening the wall yourself.
- If you turn the water back on and pressure does not return to normal, shut it off again — there is a break you have not found.
What not to do
- Do not run a shop vac, fan, or dehumidifier in standing water. Electricity and water is the hazard that turns a property loss into a personal injury.
- Do not walk into a room where the ceiling is bulging. It can release all at once, and it is full of water.
- Do not poke a hole in a sagging ceiling to 'let it drain'. That is a controlled task for someone with the equipment to catch the water.
- Do not use a household carpet cleaner to remove standing water. Most of them add water.
- Do not open windows on a humid day to 'air it out'. Manage humidity instead.
- Do not assume the water stopped when the sound stops. Check the meter.
Where the main shutoff usually is
In most Tulsa-area homes the main shutoff is either at the water meter near the curb, in a garage or utility room, or in a crawlspace where the service line enters. In a slab home it is often a valve in the garage or near the water heater, and in some newer homes there is a valve near the street in a small ground box.
Find yours now, before you need it. Turn it off and back on once a year so you know it actually moves — a gate valve that has not been operated in a decade often will not close when it matters. It is also worth attaching a tag or a label so anyone in the household can find it in the dark.
Frequently asked questions
How much water can a burst pipe release?
A great deal, and faster than most people expect. A typical residential supply line at normal pressure can release several gallons per minute, which is why a break that goes unnoticed for an hour in an empty house can put hundreds of gallons into the structure. That is the main reason shutting off the main comes before anything else.
Can I just shut off the fixture valve instead of the main?
If the break is downstream of a fixture shutoff valve — a supply line to a toilet or a sink — closing that valve isolates the leak, and it is usually faster than finding the main. If the break is in the main line itself or you cannot identify the fixture feed, go to the main.
Does insurance cover burst pipe damage in Oklahoma?
Freeze-related burst pipe damage is commonly covered as sudden and accidental discharge, but policies often exclude losses that occur while a home is vacant or unheated beyond a specified period, and they may require that reasonable care was taken. Read the freeze and vacancy provisions in your policy and confirm with your insurer.
How do I prevent this next winter?
Insulate pipes in unheated spaces and exterior walls, seal air leaks that let cold air reach plumbing, disconnect hoses and drain exterior spigots before the first freeze, leave cabinet doors open under sinks on exterior walls during cold snaps, and shut off and drain the system entirely if you are leaving for an extended period.
What if the water went under the floor?
That moves the situation from a spill to a water damage loss. Water under a floor keeps wicking into subfloor and framing, and it does not dry on its own in a closed assembly. That is a case for professional extraction and drying rather than household equipment.
