Designed for kitchens with only a cold water supply and no hot water. Perfect for workplace kitchens that require a mixer tap and a separate Zip HydroTap in the same area. Enables hot and cold mains water from the mixer tap, with Boiling, Chilled and Sparkling filtered drinking water from the Zip HydroTap. The Five-in-One delivers five kinds of water supply from the two separate taps. It's that easy!
