This is the control valve only. The Fleck 5600 SXT is the metered valve head that mounts on top of a softener tank — it is not a complete, ready-to-run water softener.
✓ Included
Fleck 5600 SXT valve head, 24V transformer, and #1 injector / 1600 brine system. Choose the drain line flow control (DLFC) button for your tank size from the options above, or select "No DLFC" if you already have one.
✕ Not included
Resin (mineral) tank, softening resin, brine/salt tank, bypass valve, and distributor tube — you'll need these to build a working softener.

Installation Requirements
The Fleck 5600 SXT 24V valve mounts to any 2-1/2" - 8 NPSM threaded tank with a 1.050" distributor tube and sits 7" above the tank top. This model ships without a Drain Line Flow Control (DLFC) button, which must be selected based on tank size: use 1.2 GPM for 8"×44" tanks, 1.5–2.0 GPM for 9"×48" systems, 2.4 GPM for 10"×54", 3.0 GPM for 12"×52", and 3.5–5.0 GPM for larger 13"×54" to 14"×65" vessels. The modular injector/drain assembly allows for quick servicing without removing the valve from the tank. Annual power consumption is minimal thanks to the single-motor design that handles both timekeeping and valve actuation. Replacement part number 94SV-56SXM24V.
