What it does for your water
The Fleck 5600SXT 32,000-Grain Water Softener is a whole-house softener rated at 32,000 grains on a Fleck 5600 SXT control valve.
The rating assumes a heavy salt dose; at a salt-saving setting expect about 24,000 grains from its 1.0 cu ft of resin, enough for up to 3 people on 15 grains-per-gallon water regenerating weekly, or 1 on 25 grains per gallon. Size it to your own water.
The Fleck 5600 SXT head is one of the most widely serviced valves; seal kits, pistons, boards and meters that name it are in the valve parts lookup.
Other listed details: features listed Programmable; mounting Freestanding; power Corded Electric; capacity stated as 1 cu ft; model 5600; material Polyglass tank.
The listing gives dimensions of 25 in (L) x 15 in (W) x 56 in (H) and complete system in the box.
