Are you heading home for winter? Before leaving the park, preparing your static caravan for the colder months is crucial. Static caravans can be at risk of flood and frost damage, so correctly draining down your prized possession can prevent considerable costs from arising come spring. If you’re not sure where to start, don’t worry. Read on for information about draining down your caravan to help ensure it’s in top condition when you return.
What is draining down your caravan?
Draining down your caravan involves removing all fluid and water from your caravan’s pipework, boiler, and water systems. You do this because, during winter, it’s common for pipes to freeze. If you leave your caravan unattended and undrained, any water in your pipework could solidify if temperatures drop below zero.Why should you drain down a static caravan?
If water is left inside your pipework, it could freeze and cause pipes to burst, which may flood your caravan. Or, it could freeze essential parts of your boiler and water systems, causing them to split, crack, or no longer work. Although you may have caravan insurance to protect your static caravan from risks, such as flooding and damaged pipework, insurers may not settle a claim if there are signs of poor maintenance. As a result, you may be liable for costs caused by lack of down draining, even if you have a policy in place.How to drain down a static caravan
Draining down your caravan doesn’t require a professional, so you can complete it yourself following the steps below.- First, switch off your heater and turn off the water supply.
- Open your caravan’s drain-down taps, usually located underneath your caravan.
- Open all internal taps until the water has fully drained.
- Flush the toilet, turn on the shower, and let the water drain out. Also remove the shower head and connecting pipe to insure it is fully drained.
- Using a compressor or a dedicated drain-down kit, blow compressed air through your caravan’s water pipes to remove any residual water.
- Pour non-toxic, caravan-grade anti-freeze into your toilet, sink, shower, and plug holes to protect against freezing and displace any residual water left in the waste pipes. Close and lock all windows, skylights, and doors to stop cold air from entering your caravan.
When should you drain down your static caravan?
Draining your caravan should be completed in preparation for winter, usually before it gets too cold. As a general rule, complete your drain downs by early November. That said, most static caravan parks have guidelines on when to complete drain downs, so speak to the park owner or check your contract first. You should also check your insurance policy for any clauses that require the caravan to be drained down while empty.What can happen if you don’t drain your caravan?
Failing to drain your caravan can be risky. It can leave your caravan vulnerable to damage, especially burst pipes and flooding. You’ll then need to pay to replace damaged pipework, which can be costly. Your caravan insurance policy is unlikely to cover damage caused by poor maintenance, so you could be liable for repair costs.How else can you prepare your static caravan for winter?
Aside from draining down your caravan, there are other steps you can take to protect your static home from cold, mildew, and other winter risks:- Clear all external drains and gutters of debris to ensure water can flow freely.
- Seal any gaps, vents, or openings around your static caravan to prevent draughts and block entry points for wildlife such as rodents or birds.
- Disconnect the gas supply.
- Secure the caravan properly, with suitable locks and surveillance equipment.
