I got mine from
www.purewindowwater.co.uk I payed a bit more for it than Russ did, but the customer service is second to none. The booster pump packed in after 6 months on mine, same booster pump you get on any of the 4040's, replaced it no ?'s asked no charge. I know they should have any way after all it's under gaurantee, but the fact you could call them up and talk to them straight away was good.
Pretty much all the setups are the same just housed differently I think.
Russ how is yours going now? Is it knocking up enough water?
