⚠️ EMERGENCY CHECKLIST – DO THIS IMMEDIATELY
If you suspect a burst pipe, act straight away:
- Turn off the stopcock (main water supply)
- Turn off electricity if water is near sockets or lights
- Call an emergency plumber
- Move valuables away from water
- Contain leaks with buckets or towels
Every minute matters – uncontrolled water can cause thousands of pounds of damage.
What Is a Burst Pipe?
A burst pipe occurs when a water pipe splits, cracks, or fails, allowing water to escape rapidly into the property. This is considered a plumbing emergency due to the risk of:
- Structural damage
- Electrical hazards
- Mould growth
- Costly insurance claims
Common Signs of a Burst Pipe
- Water pouring from ceilings or walls
- Sudden loss of water pressure
- Pools of water forming quickly
- Damp patches spreading rapidly
- Sound of running water when taps are off
First 60 Seconds: What to Do
Step 1: Turn Off the Water (Immediately)
The stopcock is usually located:
- Under the kitchen sink
- In a hallway cupboard
- Under the stairs
- Occasionally outside near the boundary
Turn the valve clockwise (to the right) until it stops.
If stiff, use grips gently — do not force it.
💡 Can’t Find the Stopcock?
If you’re unsure where it is, contact an emergency plumber while searching — guidance over the phone can prevent further damage.
Step 2: Electrical Safety
Turn off electricity if water is near:
- Plug sockets
- Light fittings
- The consumer unit
- Standing water on floors
Always switch off power with dry hands.
If unsafe, keep clear and wait for professional help.
Step 3: Call an Emergency Plumber
When calling, be ready to explain:
- That you have a burst pipe
- Your location and postcode
- Where water is visible
- Whether water and power are off
This helps prioritise the response and bring the right equipment.
What to Do While Waiting
Reduce Damage
- Catch drips with buckets
- Use towels to limit spread
- Ventilate rooms by opening windows
- Avoid walking water through the house
Protect Important Items
Move (in order of priority):
- Electrical items
- Important documents
- Furniture
- Rugs and soft furnishings
Document the Damage
Take photos and videos for insurance:
- Source of the leak
- Affected rooms
- Damaged belongings
Common Causes of Burst Pipes in Bristol
1. Freezing Temperatures (Most Common)
Across the UK, winter freezing and thawing is the leading cause of burst pipes.
Why it happens:
- Water expands by around 9% when frozen
- Pressure builds inside the pipe
- The pipe often bursts when ice thaws, not while frozen
High-risk areas:
- Loft spaces
- External walls
- Garages and outbuildings
- Under suspended floors
Most incidents occur January–February, particularly after overnight sub-zero temperatures.
2. Ageing Pipework
Bristol has a large number of Victorian and Edwardian properties with older plumbing systems.
Common issues:
- Corrosion in old copper or iron pipes
- Historic lead pipework
- Joints weakened over decades
Older pipes are far more likely to fail under normal pressure.
3. High Water Pressure
Industry data shows that water pressure above 3 bar significantly increases failure risk.
Warning signs:
- Banging pipes (water hammer)
- Leaking joints
- Noisy taps
- Short lifespan of valves and fittings
4. Accidental Damage
Burst pipes are frequently caused by:
- DIY drilling into hidden pipework
- Renovation or building work
- Fixings driven through walls or floors
5. General Wear and Poor Installation
- Poor-quality fittings
- Inadequate pipe support
- Incorrect materials
- Long-term vibration or movement
Typical Burst Pipe Repair Costs in Bristol (2025)
| Scenario | Typical Cost Range |
|---|---|
| Simple accessible repair | £200 – £300 |
| Pipe under floor | £300 – £500 |
| Pipe inside wall | £400 – £800+ |
| Emergency call-out (night/weekend) | £100 – £150 |
What affects the price:
- Pipe location
- Access difficulty
- Pipe material
- Time of day
- Extent of water damage
Water damage restoration can far exceed repair costs, often reaching £2,000–£5,000+.
How to Prevent Burst Pipes
