What To Do If a Pipe Bursts (Step-by-Step)

The Norwich Plumbing Services Team Updated 28 September 2026 5 min read

A burst pipe can flood a room in minutes. Since speed matters, here's exactly what to do in the first five and when to call a plumber.

If a pipe bursts, turn off your mains stop tap right away. Then turn off the electricity if water is anywhere near sockets or the fuse board. Then call an emergency plumber. Since every extra minute means more water damage, here’s the order to follow, with no time wasted figuring out what to do first.

Step 1: Turn off the mains stop tap

Your stop tap (sometimes called a stopcock) controls the water supply to your whole property. It’s usually:

  • Under the kitchen sink
  • In an airing cupboard or utility room
  • Near the front of the property, close to where the supply pipe enters

Turn it clockwise until it stops. This won’t drain the pipe that’s already burst, but it stops any more water joining the leak.

Step 2: Turn off the electricity if water is nearby

If the leak is anywhere near sockets, light fittings, or your fuse board, turn off the electricity at the consumer unit before you do anything else. Don’t touch switches with wet hands, and don’t stand in water near an electrical source. This is the one step worth pausing for, even in a rush, since water and electricity together can be lethal.

Step 3: Drain the system

Once the stop tap is off, open the highest and lowest taps in the house. Try an upstairs bathroom and a downstairs kitchen tap. This drains the remaining water out of the pipework and eases pressure on the burst section. Flush toilets a couple of times too; this empties the cistern.

Step 4: Contain the damage

  • Move anything valuable or electrical away from the water.
  • Use towels, buckets, or a wet-vac if you have one to limit spread.
  • If water is coming through a ceiling, pierce the bulging area with something narrow (like a screwdriver) into a bucket — this releases the water in a controlled way rather than letting the ceiling collapse under the weight.
  • Open windows and doors where safe to do so, to help air circulate and reduce how much moisture soaks into plaster, skirting, and flooring while you wait for help.
  • If the burst is near a floor, lift rugs and move furniture off wet carpet as soon as it’s safe — carpet left sitting in standing water for hours is far more likely to need full replacement rather than just drying out.

Why acting in this order matters

It’s tempting to grab towels first. The water is the obvious problem in front of you. But stopping the source at the stop tap, and removing the electrical risk, always come first. Every minute spent mopping while the tap is still on just means more water to deal with. The order above puts the highest-risk, most time-sensitive steps first. The clean-up, which can happen at any pace, comes last.

Step 5: Call an emergency plumber

Once the immediate danger is under control, get a professional to find and fix the actual burst. A DIY repair on a pressurised pipe rarely holds. If the pipe is hidden in a wall or floor, you’ll need someone who can trace it without causing more damage.

We cover emergency plumbing across Norwich and the surrounding area, including homes in Wymondham, a burst pipe callout in Dereham, and properties in Attleborough. If you’re not sure whether your situation counts as an emergency, our guide on what counts as a plumbing emergency can help you decide.

What happens next

Once the leak is fixed, don’t rush to dry everything and move on. Trapped moisture in walls or under flooring can cause mould weeks later, since it often doesn’t show up until well after the drama has passed. A plumber can tell you whether you need a real drying-out period, sometimes with dehumidifiers running for several days, or whether a damp specialist should check for hidden moisture behind plaster or under flooring. Your home insurer may also want photos and a written report of the repair for your claim, so it’s worth keeping a simple record. A few photos on your phone from during and after the event is usually enough.

Preventing it happening again

Burst pipes often link back to frozen pipework in winter, since water expands as it freezes and splits the pipe. Ageing pipework that’s simply reached the end of its life, or a sudden pressure spike in the system, are common causes too. If this is the second time it’s happened, or the pipe that burst looks old or corroded, ask whoever fixes it whether nearby sections face a similar risk — a like-for-like patch on one section doesn’t tell you anything about the rest of the run.
