I have a Cascade manual i can send you , if you'd like it just email me ( address below ) .

Water system , you put a water pump in a Aqua roll , the pump will need the correct type of socket on the caravan so you can plug it in . The pump will need a 12volt battery supply , this will go to the back of the socket inside the caravan .
Also rear the back of the socket you can fit a pressure switch , it works on pressure in the pipes , so if you open a tap the pressure drops and the pressure switch turns on the pump . When you turn the tap off presssure builds in the pipe and the switch cuts the supply to the pump . Some pressure switches come already built into the back of the socket . See here http://www.1carpc.co.uk/wcdr/new-page-4.htm

After the pressure switch , use a Y connection , take one pipe feed to the water heater and on the other feed pipe use another Y connection ( this is your cold feed ) take one end to the shower cold tap , and one to the kitchen cold tap .
From the pipe that went to the water heater you need to connect another pipe to the heater outlet , this is then taken to the shower tap and kitchen tap . 

Hope this helps .

Ps, if you use a pressure switch system you don't need to use taps with micro-switches , a pressure switch system is easier to install and there's less to go wrong .

Hi Wizard,

thanks for your reply, this is a great help and it all makes much more sense now. Our van doesn't have an external pipe connector like the one in the picture but would something like this work? http://cgi.ebay.co.uk/Caravan-Motorhome-Whale-Water-Pressure-Switch-/260622855051?cmd=ViewItem&pt=UK_Campervan_Caravan_Accessories&hash=item3cae552b8b#ht_500wt_1154
