Hi, I bought this hayward vari-flo xl valve sand filter but never knew to set it up, it was on a 18ftx18ftx6ft fish pond before I had it and it worked perfectly until the owner moved house and couldn't take it with him. http://www.inyopools.com/HowToPage/how_a_multiport_valve_operates.aspx?CommentPage=1 this is an attachment to a website that shows you how to set it up and what each feature does. I've got a new filter so don't need the sand filter anymore. £250 ono. Great deal as these are worth alot more.
Buyer to collect and transport themselves, I will help getting it to your vehicle but it is really heavy die to the sand.
