Many areas in the UK have a water supply that is naturally hard (water that contains high levels of calcium and magnesium). Water hardness can lead to the build-up of calcium and magnesium (limescale) in pipes, radiators, cylinders, pumps and boilers and can significantly reduce efficiency. More visible signs of limescale around the house tend to be around taps and bathroom fittings and in kettles, washing machines and dishwashers.
Softening of hard water is usually achieved through the use of an ion-exchange water softener in which the hardness ions of the calcium and magnesium are exchanged with sodium ions from the salt. It is this process that removes their ability to form scale and results in a ‘softening’ of the water.
Softeners need to be topped up regularly to maintain their efficiency and effectiveness.
Our granular salt is 99.9% pure which makes it ideal for use in water softerners.
