Frozen pipes are a nightmare in winter van life. Here is how to prevent them.
The Risk
Pipes freeze when exposed to temperatures below 0°C. UK winter nights regularly drop below freezing. The most vulnerable pipes are under the van (if you have underslung tanks) and in unheated cupboards.
Prevention
- Pipe insulation: 10mm foam pipe lagging on ALL exposed pipes. £3-5 per 2m at Screwfix.
- Heating tape: Self-regulating 12v heating tape wrapped around pipes. £20-40 per 5m.
- Tank heater: Silicone heating pad on water tank. £15-25.
- Drain down: If temperatures drop below -5°C, drain the entire system.
Winter Plumbing Tips
- Keep the van heated (diesel heater on low, 5°C minimum)
- Open cupboard doors under sinks to let warm air circulate
- Add antifreeze to grey water tank (specific RV antifreeze, not car antifreeze)
Conclusion
Pipe insulation and keeping the van above 5°C prevents the vast majority of freeze issues. Heating tape is for extreme cold.
