How water softeners work
Water softeners protect your home and improve the quality of water by removing mineral deposits found naturally in water.
It’s common for water, particularly in hard water areas, to contain minerals such as magnesium and calcium. These enter the water as it travels through rocks and across the ground before entering our water supply. A common symptom of hard water is the powdery residue you may see in your home, known as limescale.
When water passes through a water softener, a process of ion exchange removes these minerals. This is done using a resin which sits inside the device and collects the minerals. The softener will regularly ‘regenerate’ itself by flushing salt through the resin to clean it. All you need to do is refill the salt – the softener does the rest for you.
