Burst Pipe Emergency Checklist

A burst pipe can release water faster than most people expect. The priority is not to make a permanent repair yourself; it is to stop the supply where possible, keep occupants safe and prevent water from spreading while the fault is assessed.

Quick action checklist

• Protect people from water, sewage, heat and electricity.
• Isolate the relevant water supply when safe.
• Stop using affected fixtures and appliances.
• Limit damage without attempting unsafe repairs.
• Take photographs and give the plumber clear information.

1. Keep people away from the affected area

Wet floors, collapsing ceilings, hot water and exposed building materials can cause injury. Move children, pets, customers and staff away from the leak and create a clear path for emergency access.

2. Check for electrical danger

Do not touch appliances, plugs, lights or the distribution board while standing in water. If the board can be reached by a dry route, isolate the affected circuit or main supply. Otherwise leave the area and obtain qualified assistance.

3. Close the nearest isolation valve

If the burst is on a toilet, basin, appliance or geyser feed and a sound local valve is immediately available, close it gently. This may preserve water to the rest of the property.

4. Close the main water supply

When the local valve is missing, inaccessible or ineffective, close the main shut-off valve. Turn it steadily without forcing it. Open a cold tap briefly to release remaining pressure and confirm that the incoming flow has stopped.

5. Switch off the geyser when relevant

If the burst affects hot-water pipework, the geyser or the roof space near the geyser, switch off the geyser circuit if it is safe to do so. Stored hot water may continue to drain even after the incoming supply is closed.

6. Contain and redirect remaining water

Use buckets, towels or a wet vacuum only where there is no electrical or contamination risk. Move furniture, stock, electronics and documents. Do not puncture a bulging ceiling; the saturated material may collapse unexpectedly.

7. Photograph the source and damage

Take wide and close photographs before cleanup where practical. Record the pipe, surrounding room, ceiling or wall damage, affected belongings and meter reading. This may help diagnosis and any insurance process.

8. Contact a qualified emergency plumber

Provide the address, pipe location, whether the water is isolated, whether hot water or electricity is involved and whether the pipe is accessible. Send photographs or video so the team can prepare suitable tools and materials.

9. Avoid unreliable temporary repairs

Tape, putty and improvised clamps can fail under pressure and conceal the true condition of the pipe. Do not cut into walls or ceilings without understanding the services behind them.

10. Dry and monitor the area after repair

Once the pipe is repaired and tested, remove wet materials where appropriate, ventilate the area and monitor for staining, swelling or mould. Hidden moisture may require professional drying or further investigation.

Frequently asked questions

What causes pipes to burst?

Common causes include corrosion, excessive pressure, accidental damage, failed joints, poor installation, movement and deterioration of flexible connectors.

Can I turn the water back on after clamping the pipe?

Do not restore pressure until the temporary measure has been assessed. A weak clamp can fail suddenly and cause further damage.

Who should I contact about water damage?

Arrange the plumbing repair first, then contact your insurer or restoration provider as required. Keep photographs, invoices and a record of events.

Does a burst pipe always require replacement?

The correct repair depends on pipe material, condition, access and cause. A local repair may be suitable, while widespread corrosion may justify replacing a longer section.
