That was actually a legitimate question, toilet trailers carrying their own water supply will be using pumps to supply cisterns and taps. No header tank, imagine 100's of kilos sloshing about and what it would do to the centre of mass of the vehicle...the DVSA would have a field day.

I don't see why you would do that, besides the space taken up as well as the cost you'd then have to empty or pump back the water to the main supply tank before you set off again. We are not talking about trimming fuel loads on aircraft here, a pump based system to feed cisterns and taps would probably do.
He doesn't know or will accept it but we've saved the OP a ton of ball ache and money. Elvis if you still want to pursue this this have a look at the water system and controls on a decent caravan and how it's done.
Running water taps, flushing toilet, pumps, water storage, grey water and sceptic tanks...not all of it will be available at Wickes.
