When you turn on the tap, the water may look perfectly clear. It may not have any unusual smell or taste either. So, how could something that looks completely normal be causing problems?
The answer could be hard water.
Hard water contains naturally occurring minerals, mainly calcium and magnesium. These minerals aren't necessarily a sign that the water is unsafe, but when their concentration is high, they can leave deposits on bathroom fittings, contribute to scale inside water-heating equipment and make everyday cleaning more difficult.There is another side to the hard-water conversation that is getting more attention today: hair and skin.
If your hair feels unusually rough after washing, your skin feels tight after a shower, or your bathroom seems to develop white deposits almost overnight, your water quality may be worth checking.
What Exactly Is Hard Water?
Hard water is water containing a relatively high level of dissolved calcium and magnesium. Groundwater can become hard naturally as it passes through soil and rocks and picks up minerals along the way. This is why water hardness can vary considerably from one location to another. The interesting thing about hard water is that you may not notice it immediately.It doesn't necessarily look different from soft water.
Instead, you may notice its effects over time:
• White marks around taps and shower fittings
• Deposits on bathroom tiles and glass
• Soap that doesn't seem to lather properly
• Scale inside geysers and water heaters
• Hair that feels rough or coated after washing
• Skin that feels dry or tight after bathing
When several of these signs appear together, checking the hardness of your water is a sensible place to start.
Can Hard Water Affect Your Hair?
Think about how often your hair comes into contact with water. For most people, it happens every day or several times a week.
When the water contains high levels of calcium and magnesium, mineral residues can accumulate on the hair. Over time, this can make hair feel different from usual.
Some people notice that their hair becomes:
• Rougher and drier
• Less manageable
• Dull-looking and heavier or coated
• More difficult to rinse and style
Hard water can also affect how shampoo and soap behave because dissolved minerals can interfere with lathering.
That doesn't mean hard water is responsible for every hair problem. Hair texture and health are influenced by many factors, including genetics, diet, scalp health, hair treatments and personal-care products.
Still, if your hair consistently feels different after washing, the water you use deserves some attention too.
What Does Hard Water Do to Skin?
Your skin comes into contact with water every day — during showers, face washing and even simple hand washing.
Some people find that hard water leaves their skin feeling less comfortable after bathing. Mineral deposits and interactions between hard water and soap can contribute to a feeling of dryness or tightness.
You might notice:
• A tight feeling after a shower
• Dry or rough-feeling skin
• Difficulty rinsing soap completely
• A residue-like feeling after washing
• People with naturally dry or sensitive skin may notice these effects more readily.
Of course, hard water isn't the only possible explanation for skin problems. Weather, skincare products, bathing habits and existing skin conditions can all play a role.
But if you've changed your skincare routine and still notice the same problem, testing your water may be worth considering.
What Happens to Geysers and Appliances?
Hard water can be particularly troublesome when it is heated. Calcium and other minerals can form scale inside equipment such as:
• Geysers and water heaters
• Boilers and heat exchangers
• Coffee and washing machines
• Dishwashers
The problem isn't simply cosmetic. Scale can act as an insulating layer on heating surfaces, potentially reducing heat-transfer efficiency. Equipment may then require more frequent cleaning, descaling or maintenance.
How Does a Water Softener Work?
A conventional ion-exchange water softener is designed specifically to reduce hardness caused mainly by calcium and magnesium.Inside the system is a specially designed resin.
As hard water passes through the resin, calcium and magnesium ions are exchanged for sodium ions. After the resin has treated a certain amount of water, it needs to be regenerated using a brine solution.
The exact size and configuration of a softener depends on several factors, including
• Daily water consumption and peak flow requirements
• Number of users and application
• Available installation space
