We built this softener based on customer demand for a highly-efficient, rock-solid performing, and nice looking softener. Mission accomplished! Ultra low salt consumption, crazy-easy installation, small footprint, and an industry-leading warranty are the hallmarks of the Citymaster 5600SXT by Aqualux. Perfect for city-water installations and rural applications with iron below 2.0 ppm. It features the legendary Fleck 5600SXT control valve and and 10% cross linked resin for rock-solid performance and longevity. Ideal for applications up to 30 grains-per-gallon hard, this softener uses less than 20 pounds of salt per month in most applications.  Ships fully built and ready to install.
