PLUMBING EMERGENCIES

What should I do first when a pipe bursts inside my home?

When a pipe bursts, get people out of the wet area, shut off the water if the valve is safe to reach, and tell the plumber what is still leaking. [2]

THE DIRECT ANSWER

Move everyone away from the water first. If the home’s main water valve is easy to identify and you can reach it without crossing wet flooring or going near electrical equipment, close it by hand. Do not force a stuck valve. Watch from a dry place to see whether the spray or stream slows. Water already inside pipes, walls, or ceilings may keep dripping after the valve is closed. [2] [1] [3]

Key points

What to do in the first five minutes

  1. Get everyone clear

    Keep children, pets, and other occupants away from wet floors, a sagging ceiling, and anything electrical. If water is touching an outlet, light, appliance, electrical panel, or extension cord, do not enter the area. [1]

  2. Shut off the water if the valve is safe to reach

    If the break is at a toilet, sink, or appliance and its nearby valve is clearly identified, dry, and easy to turn, close that valve. For a break elsewhere in the house, close the main water valve. A fixture valve stops water to one fixture; the main valve stops water to the home. [2]

  3. Check from a dry place

    Watch the leak without stepping into the wet area. The spray or stream should slow as the pressure falls. Dripping may continue while water already above the break drains from the pipe, wall, or ceiling. Do not reopen the valve to test the break.

  4. Call and describe what is happening

    Tell the plumber which room is affected, where the water appears to start, whether the main valve is closed, and what the water is doing now. Mention water near electricity or a damaged ceiling before anyone enters.

Protect what you can without taking risks

  • Move dry belongings away from the edge of the water only when you can stay on dry flooring.
  • Place a container under a small drip only when the ceiling is firm and no electrical equipment is nearby.
  • Photograph the visible break and the path of the water from a dry doorway. EPA advises addressing household leaks promptly because they can damage the home. [4]
  • Do not cut into a wall, open a ceiling, or operate a wet switch to find the source.

What to report when you call

These details help the plumber understand whether pressurized water is still entering or the remaining water is draining away.
QuestionUseful answer
Is the main valve closed?Yes, no, partly, or not safely reachable
What is the water doing now?Spraying, streaming, dripping, slowing, or stopped
Where is it visible?Pipe, wall, ceiling, cabinet, floor, or room below
Is electricity involved?Wet outlet, light, appliance, panel, wiring, or none visible

When the plumber arrives, first explain what happened when the valve was closed. The plumber can confirm that new water has stopped, locate the broken pipe or connection, and explain what must be opened to reach it.

Repairing the plumbing stops new water. It does not dry wet insulation, flooring, cabinets, or ceiling spaces. Keep the main valve closed until the plumbing repair has been completed and checked for leaks.
