Frequently Asked Questions

Q: How do I drain down the water system for winter or storage?

Open the fresh water tank's drain valve, then the wastewater tank's (into a suitable container), then leave every tap inside the vehicle open (mixer taps set to their central position). There's also an internal drain valve that clears the water heater and its own pipework - open that too, give the vehicle five minutes to finish draining, then briefly run the pump to clear any water left in it. Empty the cassette toilet too.
