A very basic lesson we learned as students in geometry is that the shortest distance between two points is a straight line. This principle has been put to work for the first time ever in a spa with Artesian’s DirectFlow water routing system. DirectFlow gives hot tub users complete control of their hydrotherapy (water massage), without sending the water on a roundabout route through diverter valves, that cause loss of water pressure and diminished massage. While the implications of this technology are far-reaching, the benefits to you is this: Your hot tub seat and jets are controlled by you with your own personal topside control, and your massage is delivered straight to you without diversion or distraction from noisy diverter valves!
