Pipe Burst — What Should You Do First?
Control the water supply, avoid hazards, identify the rupture area, and understand what information helps with burst-pipe repair.
Emergency plumbing guide
Stop water feeding the rupture
Use the visible pattern to decide what you can safely control now and what information will help identify the next plumbing step.
- Shut off the closest safe supply valve when you know which valve controls the failed line.
- Use the main household shutoff if the active rupture cannot be isolated locally and water continues flowing.
- Do not turn water back on simply because the visible flow has stopped.
If the situation changes while you are checking the area, treat the new symptom as important information and avoid continuing to use plumbing that is actively leaking, overflowing, or returning wastewater.

Protect the area
The goal is to reduce uncertainty without guessing at a diagnosis. Focus on the affected fixture, water type, scope, and any change in symptoms.
- Keep people away from standing water near electrical outlets, wiring, appliances, or equipment.
- Move belongings only when you can do so without entering unsafe water or unstable areas.
- Use towels or containers only for minor residual water after the active supply is controlled.
