Guide to draining down a static caravan

Is winter coming or are you leaving your caravan for a while? Read Insuremy’s step-by-step easy guide to draining down a static caravan.

Row of Static caravans

Draining a static caravan, also known as a mobile home or trailer, is an essential maintenance task, especially before winter or long periods of inactivity. Properly draining the caravan's water and plumbing systems will help prevent frozen pipes, leaks, and damage. Here's a step-by-step guide to help you through the process:

Note: Before you begin, consult your models’ owner's manual for any specific instructions or precautions related to draining the water systems.

Materials you'll need:

1. Wrench or pliers

2. Screwdriver

3. Non-toxic antifreeze

4. Plastic hose or pipe for siphoning

5. Buckets or containers

What are the steps?

Step 1: Turn Off the Water Supply

Locate the main water supply valve or stopcock in your caravan. This is usually found inside a cupboard or under a sink. Turn the valve to shut off the water supply completely. This will prevent any excess liquid from flowing into the system during the draining process.

Step 2: Open All Taps and Drains

Open all the taps and drains inside the trailer, including the sinks, shower, and toilet. This step will allow the water to flow out freely during the draining process. Also, open any external drains or taps if your caravan has them.

Step 3: Empty All Tanks

If you have freshwater and/or wastewater tanks, you'll need to empty them. Locate the drainage outlets for these tanks. Attach a hose to the outlet and direct it into a suitable drainage area or container. You may need to use a wrench or pliers to loosen the outlet cap if it's hard to open. Allow the tanks to completely drain.

Step 4: Drain the Water Heater

If your caravan has a water heater, you'll need to drain it separately. Turn off the water heater and allow it to cool down if it has been recently used. Locate the drain valve at the bottom of the heater (often a small tap or valve). Attach a hose to the drain valve and direct it outside the caravan or into a suitable drainage container. Open the drain valve to let the water heater drain completely.

Step 5: Clear Water Pipes

To ensure that all water is removed from the pipes, you can use a manual or gravity-based method to clear the pipes. You can either use compressed air to blow the water out of the pipes or use a non-toxic antifreeze specifically designed for motorhomes and caravans. If using antifreeze, follow the manufacturer's instructions for safe use. Pour the antifreeze into each drain and flush the toilet to ensure it circulates through the entire plumbing system.

Step 6: Check for Remaining Water

Inspect your plumbing system and fixtures to ensure there is no liquid remaining. Double-check that all taps, drains, and valves are closed securely.

Step 7: Protect your investment!

After your trailer is completely drained, you may want to take additional measures to protect the caravan during the winter months or long periods of inactivity. This can include insulating the pipes or covering any external vents to prevent pests from entering.

Importance of Insurance

As a responsible owner, it's essential to take proactive measures to protect your investment. Static caravan insurance provides vital financial protection against potential risks such as accidents, theft, and damage.

It is crucial to drain down your water and plumbing systems properly. Draining down the tanks, pipes, and water heater helps prevent freezing, which can lead to costly damages. By combining the safety net of insurance cover with the proper maintenance of draining down, you can enjoy your static caravan with confidence, knowing you've taken steps to mitigate potential risks and ensure its longevity.

By following these steps, you should be able to drain your static caravan's water and plumbing systems properly. Regular maintenance like this can help prolong the life of your caravan and prevent costly repairs in the future.
