What is Soft 4?
Soft 4 is a high-capacity water softener designed to reduce calcium and magnesium minerals in hard water, helping minimise limescale across larger properties.
Is Soft 4 for drinking water?
No. Soft 4 is not a drinking-water filtration system. It is designed to soften water by reducing hardness minerals. For drinking-water filtration, it may be paired with Flow 2 or Flow Xs depending on the property setup.
Where should Soft 4 be installed?
Soft 4 is best installed in a technical room, water room, utility area, service room, garage, or other location where the main water line can be accessed.
What type of property is Soft 4 suited for?
Soft 4 is suited for larger homes, villas, and properties with higher water demand where a larger flow rate and resin capacity are required.
What does Soft 4 help protect?
Soft 4 helps reduce limescale build-up in plumbing, taps, showers, water heaters, washing machines, dishwashers, and other water-connected systems.
How does Soft 4 work?
Hard water passes through a resin bed, where calcium and magnesium ions are exchanged with sodium ions. The resin is then periodically regenerated using a brine solution.
Does Soft 4 need salt?
Yes. Soft 4 uses salt for resin regeneration. Salt levels should be checked and topped up as part of normal maintenance.
