Burst Pipe Emergency? Your Complete Guide to Fast Response Plumbing in Hampstead
A burst pipe is one of the most stressful emergencies any homeowner or landlord can face. Water gushing through your Hampstead property can cause thousands of pounds in damage within hours. Whether it's a frozen pipe that's cracked, corroded pipework, or water pressure issues, knowing exactly what to do in the first crucial minutes can save you significant expense and distress.
This comprehensive guide covers everything you need to know about dealing with burst pipes in Hampstead, NW3, and surrounding areas.
Immediate Actions: First 5 Minutes are Critical
When you discover a burst pipe, every second counts. Here's your emergency checklist:
1. Turn Off the Water Supply (Priority #1)
Location of stopcock: Most Hampstead properties have the main stopcock in one of these locations:
- Under the kitchen sink
- In the downstairs toilet/cloakroom
- External boundary box near the front of the property
- In the basement or cellar (common in period Hampstead properties)
Turn clockwise to shut off. The stopcock should turn fairly easily - if it's stiff, it may not have been used in years. Don't force it excessively or it may break.
2. Turn Off Heating and Electrics
- Switch off central heating at the boiler or programmer
- Turn off electricity at the consumer unit if water is near electrics
- Don't touch electrical switches with wet hands
- If water is actively flowing near electrical items, call an emergency electrician as well
3. Drain the System
- Turn on all cold taps to drain remaining water in the pipes
- Flush toilets several times to empty cisterns
- Turn on hot taps but leave heating OFF
- This reduces pressure and stops more water escaping
4. Collect the Water
- Place buckets under the leak
- Use towels and mops to soak up standing water
- Move furniture and valuables away from wet areas
- Roll up carpets if possible to prevent water absorption
5. Call an Emergency Plumber

Common Causes of Burst Pipes in Hampstead Properties
Frozen Pipes (Winter Peak Season)
Hampstead's period properties often have pipes in uninsulated areas:
- Loft spaces: Especially where insulation has been disturbed
- External walls: North-facing walls in Victorian/Edwardian properties
- Garages and outbuildings: Unheated spaces
- Under floorboards: Ground floor properties with air bricks
Temperature threshold: Pipes typically freeze when temperatures drop below -6°C for sustained periods. The freeze itself doesn't burst the pipe - it's when ice thaws and pressure builds that pipes crack.
Corrosion and Age
Many Hampstead properties have original Victorian or Edwardian pipework:
- Lead pipes: Common in properties built pre-1970, corrode over 50+ years
- Copper pipes: Lifespan of 50-70 years, then pinhole leaks develop
- Steel pipes: Rust from the inside out, especially in hard water areas
- Poor connections: Compression joints can fail over time
Water Pressure Issues
High water pressure (above 3 bar) can cause:
- Stress on joints and weak points
- Water hammer when taps close suddenly
- Premature wear on pipework
Hampstead water pressure: Thames Water supplies Hampstead at 1.5-3 bar typically, but pressure can spike during low-demand periods (3am-5am).
Physical Damage
- DIY accidents: Drilling into pipes, nailing through pipework
- Building work: Renovations disturbing old pipes
- Ground movement: Subsidence common in clay soil areas of Hampstead
- Tree roots: Mature trees affecting underground pipes
