Static Caravan Drain Down & Frost Damage

Why Drain Down Matters

When winter temperatures fall below freezing, any water left in your caravan’s pipes, tanks, or boiler can expand and burst. A proper drain down removes this water, protecting your plumbing system, heating, and fixtures from expensive damage.

• Frozen pipes can split or burst, causing flooding when thawed.
• Repairs can cost hundreds — sometimes thousands — if not prevented.
• Most insurance policies require evidence of a proper drain down to remain valid.

Steps to Drain Down Safely

1. Turn off the mains water supply and disconnect your hose.
2. Open all taps and shower heads (hot and cold) to let water escape.
3. Flush toilets and drain the cisterns.
4. Empty the water heater and any onboard tanks.
5. Use compressed air or drain valves to clear any remaining water in pipes.
6. Leave taps open over winter to allow expansion space for any residual water.

Many owners hire a professional plumber or park service to complete the drain down for a small fee — often the safest option.

Insurance & Park Rules

Some caravan parks make winter drain down a requirement, while most insurance policies expect it as part of reasonable care. If damage occurs and there’s no record of a drain down, insurers may refuse a claim.

Always keep a receipt or written confirmation if you use a professional service — it can be crucial for insurance claims.
