Burst Pipe? Emergency Steps Before the Pros Arrive
Exactly what to do in the first 30 minutes after a pipe bursts: shut-offs, electricity, draining the system, and what to leave for the professionals.
A burst pipe can push dozens of gallons a minute into your home. The good news: the first three moves are simple, and they cut the damage dramatically. Here they are in order.
The first five minutes
- Shut off the main water valve. It is usually where the water line enters the house: basement front wall, crawl space, or near the water meter. Turn clockwise until it stops. If the valve is stuck or broken, the street-side curb valve is the backup, and your water utility or a plumber can close it.
- Kill electricity to affected areas, if safe. If water is anywhere near outlets, appliances, or the panel, switch off the relevant breakers, but only if you can reach the panel without standing in water.
- Open faucets. After the main is off, open the lowest faucet in the house (basement slop sink or tub) and a top-floor faucet. This drains the remaining water out of the pipes instead of out of the break.
The next thirty minutes
- Find and photograph the break if it's visible. Your insurer will want to see the failed pipe; adjusters read "sudden failure" very differently from "old corrosion," and photos protect you.
- Move belongings out of the wet zone; put foil or blocks under furniture you can't move.
- Call a 24/7 restoration company for extraction and structural drying. Speed matters: drywall and flooring that dry within a day are usually saved; wet past 48 hours, they're usually demolition. See what to do in the first 24 hours for the full sequence.
- Call a plumber to repair the pipe itself (restoration companies dry the building; most don't do plumbing repair).
- Call your insurance company the same day. Burst pipes are the classic covered loss on homeowners policies. Keep every receipt.
Winter bursts: the frozen pipe special
Long Island and Westchester see a burst-pipe wave every deep freeze. If a pipe is frozen but not yet burst: open the faucet it feeds, warm the pipe gently (hair dryer, space heater in the room, towels soaked in hot water), and never use an open flame. If it has already burst, the steps above apply, plus: leave cabinet doors under sinks open and let vulnerable faucets drip until the cold snap ends, because where one pipe froze, others are close behind.
What NOT to do
- Don't run a household vacuum on standing water.
- Don't turn the water main back on before the repair is done.
- Don't rip out wet drywall yourself before documenting it for insurance.
- Don't assume "it looks dry" means it is dry; water inside wall cavities is invisible and is exactly what turns into a mold problem. Professionals verify with moisture meters.
FAQ
Where is my main water shut-off valve?
In most NY-area homes: the basement wall facing the street, near the water meter, or in a crawl space or utility room. In condos and apartments it may be at a fixture or riser; ask building management. Find yours today, before you need it.
Does insurance cover a burst pipe?
Generally yes: sudden pipe failures are the textbook covered water loss, including tear-out to reach the pipe, drying, and repairs, minus your deductible. The exception is a pipe that failed from long-term neglect, so document the break and report promptly.
How much water comes out of a burst pipe?
A typical half-inch supply line can release on the order of 10 to 15 gallons per minute at household pressure. That's a flooded room in under half an hour, which is why the main shut-off is step one, not the mop.
Do I need a plumber or a restoration company first?
Shut the main yourself first, then call both: the restoration company starts extraction and drying (the time-critical part) while the plumber repairs the failed pipe. Neither replaces the other.
