Hi, as many know we go to a lot of the shows, and like most try not to buy anything. Anyway while at Malvern we got a Nature Pure. http://www.purewateronline.co.uk/ Something we had thought about for a long time now, mainly after have drained about 1" of sand / **** from our tank after wintering in Spain, although we lugged gallons of water from the Mercadona ( in the car ) of course and then carting loads of bottled water around with us. oh: And had we not drained and cleaned the tank when we got home we would have just filled with water here, and not knowing what it was or what was in it ! Well I fitted it when we got home and went away for a long weekend, and must say very pleased with it, like the fact it has a separate tap, and like the taste, much better than out cheap jug water filter we use indoors. So very pleased with our purchase and wish we got one years ago. oh: So thanks for all the advise we read on here about them and glad we got one in the end, and as far as we are concerned money well spent. :thumb: Bob.
