Built to Perform, Designed to Last
Clear LCD Display
Easy-to-read backlit screen with intuitive programming. Set your hardness level, capacity, and regeneration time in just a few minutes.
Meter-Initiated Regen
Regenerates only after a set volume of water is used — not on a fixed timer — so you're never wasting salt or water unnecessarily.
Proven AC Drive
The 5600's AC motor design has been refined over decades of residential installations and is known for long service life and predictable performance.
Day Override Option
The day override prevents you from ever running out of soft water — ideal for households with variable water usage patterns.
Downflow Brine Draw
12V downflow brine system delivers thorough resin bed regeneration for consistent softening performance cycle after cycle.
Fittings & Manual Included
Comes complete with brine line installation fittings and a full owner's manual. Ready to install right out of the box.
