When a water pipe bursts, close your main water shutoff right away, then open a low faucet to drain the remaining water from the lines. After that, keep clear of any electrical hazards and start removing standing water so it does not soak further into the floors and walls.
Find the Main Shutoff Fast
The main valve is usually where the water line enters the home, often near the meter in a basement, utility room, or crawl space. Turn it clockwise until it stops. If it is stuck, do not force it hard enough to break it. In an apartment, alert the super, since the valve may serve the whole building.
Drain What Is Left in the Pipes
Even after the main is off, the pipes still hold water. Opening a faucet on the lowest floor lets it flow out there instead of through the break. Flushing toilets once can also help empty the lines.
Handle the Water Safely
If water has reached outlets, cords, or appliances, do not touch them. Switch off power at the breaker only if you can reach it while standing somewhere dry. Then use towels, mops, and buckets to remove water. Open windows and run fans once power is safe.
Do Not Try to Patch It and Turn the Water Back On
Tape or clamps sold in hardware stores can slow a small leak, but they are not a real repair. Turning the water back on with a weak patch can lead to a second burst. Keep the water off until a plumber has fixed or replaced the broken section.
Take photos of the pipe, the wet area, and anything damaged. Keep receipts for cleanup supplies. Your insurance company may ask for them.
A burst pipe often means other sections are worth checking, too. Since one failed pipe can hint at others of the same age, a broader look at your home’s water lines may be worth scheduling.
