What Should You Do in the First Hour After a Pipe Bursts?

The first move is to stop the flow. Locate your main water shutoff valve, usually near the water meter or where the main line enters the house. Turn it clockwise until it stops. If you are unsure which valve is which, check your home's plumbing diagram or ask a plumber for guidance.

If the burst is in a specific fixture, like a toilet or sink, you may also have a local shutoff valve. Close that too. While you are at it, open a few cold water taps to drain the remaining water from the pipes. This reduces pressure and limits further leakage. Keep the main valve off until repairs are complete.

• Find the main shutoff valve before an emergency happens.
• Label the valve with a tag or marker for quick identification.
• Turn the valve clockwise to close it fully.
• Open taps to drain pipes and relieve pressure.
• Keep the valve off until the pipe is repaired.

Move furniture, electronics, documents, and personal items out of the wet area. Place them on dry ground or a high shelf. If an item is already soaked, set it aside for professional drying. Do not try to turn on wet electronics, as that can cause further damage or a fire risk.

If you have area rugs or curtains, take them out as well. Hang them to dry if possible. The goal is to prevent water from soaking into porous materials and causing mold. In a humid climate, mold can start within a day, so act fast.

Use towels, mops, and a wet/dry vacuum to remove standing water. Open windows and doors to increase airflow. Run fans and a dehumidifier if you have them. The faster you dry the area, the less chance of warping, staining, and mold growth.

For thorough drying and sanitizing, local water damage pros use commercial equipment and methods. They can assess hidden moisture in walls and floors. If the water is contaminated or the area is large, wait for the pros to handle it. Your safety matters more than saving time.
