All our water softeners are factory set to produce water that is 100% soft. If you require slightly blended water – recommended on Combi/Condensing Boilers and in areas of hard water that have a green/blue build up in the scale – open blender bypass on the softener control valve slightly – until it takes 6/7 drops of the dark liquid to get a red to green colour change, as per the original water hardness test. This blended water setting can only be done when the softener is in Service.
