Water Softener Systems


R/O Water System
A reverse-osmosis drinking water systems significantly reduces unwanted substances bigger than 0.0001” such as carcinogens, heavy metal ions such as cadmium, chromium, lead and mercury; chlorine, cryptosporidium, salts, turbidity, nitrate, VOC’s, organic compounds, dissolved solids, tastes and odors leaving only clean, great tasting water.
AIO Systems from Nelsen Water
Iron and Sulfur are two of the most common elements found in nature. While both are extremely important for every day life, both are a nuisance in water and can cost you money and frustration. Iron staining is a common problem in homes today. It causes orange staining on fixtures, as well as dingy clothes and sometimes can have negative effects on both hair and skin. Sulfur is easily detected by the presence of a “rotten egg” odor, and is sometimes associated with yellow staining. All of these problems can be eliminated with the Nelsen AIO™ Air Injection Oxidizing Filtration System.
Automatic Valves
Clack’s WS1 Automatic valve is a state-of-the-art control head designed for residential and commercial applications requiring flow rates up to 27 GPM. It has a backwash ability capable of servicing up to 22″ diameter tanks.
The valve acts as a primary center that directs and regulates all cycles of water softening or filtration. It can be set to perform downflow regeneration or simply backwash and rinse.
