How do water Softeners Work?

If you’ve ever dealt with limescale buildup, soap scum, or dry skin after a shower, hard water may be the culprit. But what exactly is a water softener, and how does it work to solve these issues? In this guide, we'll break down the science behind water softeners and why they might be the solution you’ve been looking for.

How do water softener systems work?

Water softeners use a process called ion exchange to remove hardness minerals from your water, for example calcium and magnesium.

Water softeners are installed at the point of entry for water to your home, which means the system can soften your water before it flows through your home.

1.      Mineral tank: hard water enters the mineral tank, which contains resin beads charged with sodium ions.

2.      Ion exchange: as water passes through the resin, calcium and magnesium ions are attracted to the beads and swapped with sodium ions.

3.      Softened water: the now softened water continues its journey through your plumbing, free of hardness minerals.

Water softeners are effective at reducing limescale build up and protecting your appliances from damage. However, they will not filter your water from other harmful contaminants. At Pure Water Systems, we recommend bundling your water softer with a drinking water filtration or purification system.

Why do water softeners use salt?

Salt is used purely as a regenerant – to wash accumulated hard water salts to drain and to recharge the softening resin. The softening process relies on resin giving up sodium. When salt (sodium chloride) is passed through the softening resin, the sodium is used to re-charge the resin and the chloride combines with accumulated hard-water salts. It is important to note that salt is used only during regeneration and is washed from the resin bed completely (during the last regeneration cycle) before the water softener is returned to service.

Benefits of using a water softener system 

Protect your appliances: by reducing limescale, water softeners extend the life of water heaters, dishwashers, and washing machines.

Softer skin and hair: soft water is gentle on the skin and hair, preventing dryness and irritation.

Cleaner dishes and laundry: without mineral deposits, soap and detergent work more effectively, resulting in cleaner dishes and softer clothes.

If you notice limescale on faucets, dry skin, or reduced soap lather, it may be time to invest

in a water softener. Water softeners play a crucial role in maintaining your home’s plumbing and enhancing the quality of your water.
