I am confused regarding how to setup the water supply on my 2005 480. I usually connect the external pump located in the full aquaroll and switch it on at the control panel priming the system as per the book, the water heater is filled and so is the underslung water tank [I think]. The water supply works fine so why the confusion, well the book says there are three supply systems,
1 - the external aquaroll
2 - the underslung water tank [essential in winter]
3 - direct from mains using a waterline connection.
#The book then goes on to describe how to fill the tank, O.K.
The way these 3 ways are mentioned seem to indicate that the onboard tank can be used without the need for the external aquaroll but if so how is the tank filled. Also the book says when using the external pump to fill the system the pump can be left on and will switch off when the system is full. I don't think my pump is switching off but that could be a simple adjustment to the pressure switch. Finally, can someone please tell me what is the correct way to setup the water supply on this model of van,
Thank you and sorry to be long winded,
