01 DuraWater 48k vs Fleck 5600SXT Air

Target Contaminant

Edge: Tie

The DuraWater 48k Grain Black Softener is engineered specifically for water softening. It uses a 48,000-grain capacity to remove hardness minerals like calcium and magnesium. In contrast, the DuraWater Fleck 5600SXT Air is designed as an iron filter. It targets high iron content and the associated rotten egg smell. This unit offers a chemical and salt-free solution for iron removal. You need to choose based on your primary water issue. If hardness is the problem, the softener is the correct choice. If iron and odor are the concerns, the iron filter is better suited for your needs.

Capacity and Size

Edge: Tie

Physical dimensions and capacity differ significantly between these two models. The DuraWater 48k Grain Black Softener features a larger tank with dimensions of 14 inches wide, 14 inches long, and 62 inches high. Its 48,000-grain capacity indicates a substantial ion-exchange capability for softening. The DuraWater Fleck 5600SXT Air is more compact, measuring 10 inches wide, 10 inches long, and 40 inches high. It is described as a 10×40 inch unit. The softener is taller and wider, requiring more space. The iron filter is smaller and may fit in tighter utility areas. Consider your available installation space carefully before deciding.

Control Valve

Edge: Tie

Both systems rely on the same core automation technology. The DuraWater 48k Grain Black Softener utilizes the 5600SXT Metered On-demand control valve. The DuraWater Fleck 5600SXT Air also uses the Fleck 5600SXT valve. This valve is known for reliability and durability in water treatment applications. It provides automated backwash cycles for both units. The softener features double backwash engineering, which may enhance cleaning efficiency. The iron filter includes a pre-programmed digital control valve. Since both share the same valve model, the operational logic and timing features are likely very similar. You get consistent automation regardless of your choice.

Installation Features

Edge: Tie

Installation details vary slightly between the two products. The DuraWater 48k Grain Black Softener comes with a brine tank, bypass, and 1-inch adapters. These components facilitate connection to your plumbing system. The DuraWater Fleck 5600SXT Air ships with a threaded bypass included. It is also noted to work well with both submersible and jet well pumps. The iron filter tank is described as structural mineral tank that ships loaded, which may simplify setup. The softener includes specific adapters for connection. Both units appear designed for straightforward installation, but the included hardware differs. Check your existing plumbing connections to ensure compatibility with the provided fittings.

Color and Build

Edge: Tie

The visual appearance and tank construction differ between the models. The DuraWater 48k Grain Black Softener is black in color. Its tank is part of a softening system designed for hardness removal. The DuraWater Fleck 5600SXT Air is almond in color. It uses a structural mineral tank, which is noted for durability. The model is listed as silver, but the color is almond. This difference in color may matter if the unit is visible in your home. The black softener offers a standard aesthetic for utility rooms. The almond iron filter may blend better with certain decor styles. Both are built for long-term use with their respective filtration media.
