The NuvoH2O Manor System uses revolutionary technology to lower the pH level of water based on the basic scientific process of chelation in which the mineral ions causing hard water, principally calcium and magnesium, are bound to the chelating agent in NuvoH2O’s FDA-approved, proprietary formulation, which keeps the minerals soluble and unable to cause hard water problems. Prevents scale build-up and removes existing hard water scale. For home with 4 or more residents or for homes over 2,000 sq ft. Cartridge Lifespan: about 50,000 gallons. FDA & NSF approved. The resulting water is soft and healthy for all of your household uses, including drinking, bathing, washing, and lawn and plant watering. In addition to the NuvoH2O softener and its cartridge, your package also includes a manual, mounting back plate, mounting bracket, screws, and housing wrench. Not appropriate for homes with a private well. Not recommended for closed loop recirculation systems or wood fired boiler applications. Over tightening the fitting can, and will, cause the system to fail prematurely. In homes with copper piping, air in the line can cause oxidization of the piping. The NuvoH2O System works to remove the copper oxide, possibly resulting in blue tinged water for a short time. This is not cause for panic The effect is harmless and will dissipate over time.
