I looked into this a few months ago when buying a new van and it seems to me that the current systemin most vans is a waste of time as you cannot use both sources at the same time and cannot travel with water inboard. With a small redesign and a little money it could automaticly fill the inboard and then you refill the aquaroll and you would have 80 litres to use without doing a thing.Hi Bj,
First let me say that if your water filling/control valves are way forward under the left hand seat (as you look forward) then you can ask your dealer to move them to a more convenient position, such as just behind the front flap at the bottom of the chest like you said.
Swift have had a lot of complaints about the positioning of the valves and are authorising dealers to move them to a more sensible position. If your dealer does not know this then ask him to contact Swift, or contact them yourself.
OK, so, meantime............compare the instructions in your handbook with the valve positions it gives on the big sticker on the dropdown front flap. If they are different, go with what it says on the sticker.
There is no automatic refilling, no automatic changover, you do have to set the valves in the correct positions yourself.
There is one valve (the plastic things in the pipework that have a sort of levers on them) that is opened only when you are filling the on-board tank,at all other times it must be closed. The other valve is the one that decides whether you use from the on-board tank or the Aquaroll/Waterhog.
As I do not have our van here right now (it is away getting those valves repositioned!!) I cannot tell you exactly the directions the levers should be in, you will need to refer to what it says on the sticker.
So..........if you do want to use your on-board tank at all, first you fill the carrier, plug in the hose to the van, then you fill the on-board tank from it. Then you close the tank-filling valve.
Then you set the other valve to the position for using from the on-board tank so you have water to the taps.
Then you go and refill your carrier and connect it up again so it is ready for when you next need it.
When the water in the on-board tank is used up you then need to either refill it from the carrier or switch over to using direct from the carrier. Both alternatives will involve going under the seat to reposition the valves, hence the need to get them moved to a more sensible position.
If you do not want to bother with the on-board tank then you can use only directly from the water carrier and the valves can be left in that one position.
Take some time to study the instructions and try it out, you will soon get the hang of it. It took us a while, mainly because our handbook was wrong and we had not noticed the other instructions stuck inside that front flap. Once we followed them it was ok.
We do use the on-board tank, it is handy to have plenty of water available, often saves having to go out in the rain to refill!
Just remember to empty your Wastemaster/Wastehog regularly as it will not hold all that water!
