Burst Pipe Emergency – What To Do Immediately

04 March 2026

Burst pipes can flood a home within minutes. Learn how to shut off water quickly and reduce damage before calling a plumber.

Why Burst Pipes Can Cause Serious Damage

A burst pipe is one of the most common plumbing emergencies in homes. When a pipe splits or cracks, water can escape rapidly and begin flooding floors, walls and ceilings. Even a small pipe can release a surprising amount of water within minutes.

Burst pipes are especially common during cold weather when water inside pipes freezes and expands. However, pipes can also burst due to corrosion, high water pressure, poor installation or ageing pipework.

Acting quickly can significantly reduce the damage caused to your home.

How It Works

Step 1 – Turn Off the Main Water Supply

The most important step when dealing with a burst pipe is stopping the water supply.

Every property has a main stopcock, which controls the water entering the home. This is usually located:

• under the kitchen sink

• inside a utility cupboard

• near the water meter

• where the water pipe enters the property

Turning the stopcock clockwise shuts off the water supply and prevents further flooding.

If you cannot find the stopcock inside the home, there may also be an external stop valve near the property boundary.

Step 2 – Drain the Plumbing System

After shutting off the water, open taps around the house.

This allows remaining water in the pipes to drain out and helps relieve pressure in the system. Reducing pressure slows the flow of water from the burst pipe.

Flushing toilets can also help remove water stored within the plumbing system.

Step 3 – Reduce Water Damage

Once the water supply has been stopped, take steps to limit damage inside the property.

You can:

• place buckets or containers under leaking pipes

• use towels to absorb excess water

• move furniture and electrical appliances away from wet areas

• ventilate the area to help surfaces dry

Quick action can prevent further damage to flooring, plaster and electrical systems.
