It is that ‘Motorhome Draindown’ time of year again!! Scotland reached -5degrees last night.
Unless you can leave your van with frost protection heating in… is what we have to do:
1. Empty the fresh water tank by unscrewing the big red screwcaps on the top of the tank (Usually under the bench seat), reaching in and pulling the plug out. Or , you may have an external drain tap. ? . Possibly near the grey water drain tap / valve .
Caravan owners also do the next couple of steps….
2. Next to the heater and water boiler there is a red button or blue butterfly. Push the red button down / turn the blue butterfly.
3. Open all your taps/shower on warm and FLUSH THE LOO (Many forget this bit). The taps will be spitting. When they have all spat their last drop, Leave the taps open and switch off your pump /or switch off your 12v at your door or dashboard control panel , or the Pumpe Fuse on the Schaudt fuse box .

This avoids droplets of water/ice splitting your taps at a cost of over £100 per tap.
4. Some Esprit and Globetrotter XLi also have two drain taps which are cunningly concealed, one under the kitchen next to the pump. Yellow flap flip upwards to drain. two just next to the wall in front of the water tank undo the ‘tap’.
Also obviously open your waste tank with the key and drain it out and empty the loo cassette.

This is the general theory of what is required , but there should be a specific description in your Manual .
