A burst pipe is one of the most stressful plumbing emergencies a homeowner can face. Water can pour into walls, ceilings and floors within minutes, causing thousands of pounds of damage if you don't act fast. The good news is there are a few simple steps you can take right now to minimise the damage while you wait for an emergency plumber.
Step-by-Step: What to Do Right Now
Turn off the stopcock (mains water)
Your stopcock is usually under the kitchen sink, in the airing cupboard, or near the front door. Turn it clockwise to shut off the water supply to the whole house. This is the single most important thing you can do.
Turn off the central heating
If your burst pipe is part of the heating system, switch it off at the boiler. Let the system cool down before anyone touches it.
Open all cold taps to drain the system
Once the stopcock is off, open all the cold taps in the house to drain remaining water from the pipes quickly. This reduces the pressure and the amount of water that can leak.
Switch off electricity if water is near sockets or fuse box
Water and electricity are a dangerous combination. If water is leaking near sockets, light fittings, or your fuse box, turn off your electricity at the consumer unit (fuse box) immediately.
Contain the water and protect your belongings
Put buckets, towels, and plastic sheeting down to catch water and protect floors and furniture. Take photos and video of the damage for your insurance claim.
Call an emergency plumber
Don't try to fix a burst pipe yourself unless you're a qualified plumber. Call a professional who can locate the burst, repair or replace the pipe, and check for any other damage.
What Causes Pipes to Burst?
In the UK, burst pipes are most common in winter when water inside pipes freezes and expands. But pipes can also burst due to:
- Corrosion and rust in older pipework
- High water pressure putting stress on joints
- Ground movement or building settlement
- Accidental damage during DIY or building work
- Tree roots penetrating underground pipes
How to Prevent Burst Pipes
Most burst pipes are preventable. Here's what we recommend:
- Insulate your pipes — especially those in lofts, garages, and outside walls. Foam lagging is cheap and effective.
- Know where your stopcock is — make sure everyone in the house knows where it is and that it turns freely.
- Keep your heating on low — during cold snaps, keeping the heating on a low setting overnight stops pipes freezing.
- Get your plumbing checked regularly — a plumber can spot corroding or weakened pipes before they fail.
