Who is Fleck

Fleck is a tried and trusted name in water treatment and originated from LW Fleckenstein, who patented the ‘Fleck Closure’ valve, better known as the ‘Fleckenstein valve’ in 1955. The Fleck valves are now manufactured by Pentair Water, who can provide technical support.

Fleck Systems, which sells Fleck softeners as well as parts, including replacement valves and backwashing filters, is owned by US Water Systems, and provides sales support.

Important Features

The Fleck 5600SXT 48,000 Grain Water Softener has a number of features that make it one of the most versatile and convenient water softeners in the market.

Compact Turbine-Electronic Meter

This provides more accurate and flexible measurement of water flow than a mechanical flow meter and it has less moving parts so less potential for breakage.

Solid-State Digital Programmable Control offering Four Modes of Operation

This feature offers four modes of operation according to what is most convenient for the user:

  • Immediate meter regeneration – regeneration will occur as soon as the set volume of water has been treated;
  • Delayed meter regeneration – regeneration will occur at a convenient time after the set volume of water has been treated;
  • Delayed time clock regeneration – regeneration will occur after a set amount of time has elapsed; or
  • Day of the week regeneration – regeneration will occur each week on a certain day.

Remaining Water Volume Monitor

The digital display will indicate how many gallons of water remain to be treated before salt must be added to the brine tank.

Memory Backup

In the event of a power failure, or the power supply being accidentally un-plugged, the programmable display will store the remaining water volume, the date and time, and the operational mode settings for over 48 hours, meaning you won’t have to reset it when power is restored within that time.

LCD Display

The digital controls have a backlit LCD screen that is easy to read at any time of day, and easy to use touchpad buttons.

Double Backwash

The regeneration cycle provides a double-backwash (one slow and one rapid backwash) to improve the efficiency of the process.

Safety Float System

The safety float in the brine tank prevents over-filling and the tank has an overflow outlet that can be linked to the backwash drain.

Water Capacity, Pressure and Temperature Range

The 5600STX has a water capacity of 20GPM (1.26l/s or 75.71l/min) at a hydrostatic pressure of 300psi (20.68bar) and a maximum working water pressure of 125psi (8.6bar).

A minimum water pressure of 20psi (1.4bar) is required for the regeneration valve to operate correctly.

The water softener should be installed in its own cabinet in the house, or it can be placed in the garage. If the water softener is installed outdoors, it should be screened from sunlight to avoid UV damage and must not be exposed to freezing temperatures of less than 34°F (1°C).

The water softener has a maximum operating temperature of 110°F (43°C) and must be installed before any water heating device.

Water and Salt Consumption

The regeneration cycle of the 5600STX discharges about 80 to 100 gallons of water to drain during the regeneration cycle.

The unit will consume 24lb (10.9 kg) of salt for each 48,000 grains of hardness treated, or approximately a 50lb (22.7 kg) bag of salt per month for a family of four, depending on the level of water hardness. The capacity of the system (48,000 grains) divided by the hardness of the water will indicate the volume of water in gallons that can be treated between regeneration cycles.

The purest level of salt available should be used, solar or purified extra coarse salt, but not granulated or mineral or rock salt.

Power Rating Consumption

The 5600STX is rated at 8.4VA and runs on 110V-120V 50-60Hz with its own power supply rated at 15W reducing the voltage to 24V.

It can be purchased for use with other voltages.

Size, Dimensions and Shipping Weight

The Fleck 5600SXT 48,000 Grain Water Softener tank itself is 54” (137cm) tall but with its digital readout head it needs about an extra 7.5” (18.75cm) to 10” (25.5cm) clearance, and it has a 10” (25.5cm) diameter.

The brine tank is 15” (38cm) wide by 17” (43cm) deep and 34” (86.5cm) tall.

The shipping weight of the water softener system is 98lbs (44.5kg).

Warranty

The Fleck 5600SXT has a 5-year warranty on the valve and parts, and a 10-year warranty on the double-skin tank. The length of the warranties is an indication of the level of confidence the manufacturers have in the quality of their products.

Reviews

The Fleck 5600SXT 48,000 Grain Water Softener has received overwhelmingly positive customer reviews on Amazon. The only complaints related to the difficulty in inserting the resin beads (some suppliers pre-load them) and the lack of detailed installation and setup instructions. So, if you’re not experienced with plumbing installations, it would be advisable to have it installed and set up by a professional, as it will also require additional fittings that are not shipped with the system.

There were also some complaints about the nylon bypass valve supplied with the system, and several people had replaced it with a metal bypass valve.
