I do have an Artesian. Unlike our panning friend (whom may very well sell a cometing spa line) I have first hand experience. The Piper Glen is in the Platinum Line of spas. From what I have learned prior to purchase, the Platinum line was like the Porsche of Spas. I asked for some figures and they report a 1.4% or less problem rate with their spas. Industry wide that is great. As for HP - I shopped long enough to know that all rate their pumps what they want basically. They rate at break speed. I am not sure that the Direct Flow individual control pump is rated at break or at standard, but, I have used one, and I can tell you that there is nothing like it. I spent some money on that spa, but there is not another one like it, and I am sure of that.
