Fleck 5600SXT 48,000 Grain Water Softener – Complete Whole-House System

Fleck 5600SXT 48,000-grain water softener

This complete water softener is built around the Fleck 5600SXT, one of the most trusted metered control valves in residential water treatment. Rated at 48,000 grains of capacity, it is well suited to typical family homes, ending the scale, spotting, and dry skin that hard water causes while keeping salt and water use efficient.

Why the 5600SXT is a favorite

The 5600SXT combines a proven, serviceable valve body with a straightforward digital controller. Its metered operation regenerates based on the water you actually use rather than a fixed timer, which trims salt and water waste and keeps soft water flowing without guesswork. Field-replaceable parts make long-term ownership simple.

How it works

Hard water passes through a bed of ion-exchange resin that swaps the calcium and magnesium responsible for hardness for sodium. When the resin nears capacity, the 5600SXT regenerates it with a brine rinse and returns to service automatically. The result is consistently soft water that protects plumbing, water heaters, and appliances.

What you get

• 48,000-grain capacity sized for many family households.
• Metered efficiency that regenerates on demand, not on a clock.
• Serviceable, widely supported valve with readily available parts.

Correct sizing depends on your hardness and household size, so we will confirm the 48,000-grain rating fits your home or recommend the right capacity. Send us your numbers and we will set it up for efficient operation. Ships free in the US with manuals and knowledgeable support for a softener designed to run for years.

A softener you can rely on for years

Part of the 5600SXT's popularity is how well it is supported. Because the valve has been an industry standard for so long, parts are easy to find and service is straightforward, which keeps the total cost of ownership low over the softener's long life. It is a system you can maintain yourself with basic guidance, rather than one that forces a service call for every small task.

Sized right, set up right

A 48,000-grain rating suits many households, but the ideal capacity still depends on your hardness and daily water use. Share those details and we will confirm the fit or suggest a different size, then help you program the controller for efficient regeneration. Full manuals and knowledgeable support come standard.
