Protecting Your Plumbing from Winter Frost
Hampshire winters can be harsh on plumbing systems. Frozen pipes are one of the most common and costly plumbing emergencies during cold weather. This comprehensive guide helps you protect your home from frost damage.
Understanding the Risk
When water freezes in pipes, it expands by approximately 9%, creating enormous pressure that can burst even thick metal pipes. The damage often occurs when pipes thaw and water flows freely from the damaged areas.
High-Risk Areas in Your Home
- Unheated basements, cellars, and crawl spaces
- Pipes in exterior walls with minimal insulation
- Outdoor taps and exposed garden pipework
- Pipes in garages, sheds, and outbuildings
- Water tanks and cisterns in loft spaces
- Pipes near uninsulated windows and drafty areas
Prevention Strategies
Pipe Insulation
- Install foam pipe insulation on all exposed pipes
- Use waterproof insulation for outdoor applications
- Pay special attention to bends and joints
- Insulate both hot and cold water pipes
Heating and Ventilation
- Maintain consistent heating, even when away
- Open cabinet doors to allow warm air circulation
- Seal air leaks near pipes and in basements
- Install space heaters in vulnerable areas
Water Flow Management
- Let taps drip slightly during extreme cold
- Know your main water shutoff location
- Drain outdoor taps and irrigation systems
- Turn off water to unused buildings
Emergency Response
If you suspect frozen pipes:
- Turn off water at the mains immediately
- Turn off heating system if pipes have burst
- Open all taps to drain remaining water
- Never use open flames to thaw pipes
- Call a professional plumber immediately
