The MYRA water softener meets the needs of users looking for high salt capacity. Its single-tank injected-polystyrene body ensures rugged durability for long-term use. Its translucent one-piece cover gives a clear view of the remaining salt level, simplifying refilling while preserving the unit's aesthetics.
This version is offered with a choice of two Fleck volumetric electronic valves: the 5800 LXT or the 5800 XTR. Both regenerate on demand (volumetric meter), for optimised salt and water use and constant softened water.
