Frequently Asked Questions
Q: How do I drain down and winterize the water system before I stop using the caravan?
If you can, angle or tilt the caravan so its drain points sit at the lowest spot, then cut power to the pumps from the control panel. Turn every tap and mixer to roughly the halfway position, not forgetting an external shower point if your caravan has one, then pull off the shower handset to empty out any trapped water.
Next, let the water heater empty through its own drain valve, and do the same for the on-board tank's valve where fitted, leaving both open afterwards. If your caravan has grey waste tanks, pull the plugs from the sinks and open their own drain tap too, plus any other drainage points around the vehicle. Empty the external pump or aqua-source last and bring it inside for storage over winter.
Bear in mind the shower tray tends to hold onto a little water regardless - you'll likely need to mop up the last bit by hand. And double-check any ceramic-disc mixer tap handles are pushed all the way up to central, otherwise one side won't drain fully and you risk frost damage that your warranty won't cover.
