All these effects are common implications of water being too hard.

Where does hardness come from?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Hard water is not the same as impure water. Remember how it\u2019s been mentioned before that naturally occurring water carries essential minerals like calcium and magnesium. The water that has an adequate amount of these minerals is beneficial to the body. Hard water has more of that, more than what our hair, skin, clothes and appliances need.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Hard water has a high amount of dissolved minerals like calcium and magnesium. Let\u2019s try and understand how water becomes hard. When rain water falls on the ground, it has a long journey before it reaches your tap. It travels through rock, soil and when it does that, it dissolves calcium and magnesium on the way. Many sedimentary rocks contain calcium and this is how it gets dissolved in the water as well.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Borewell water, which is one of the major sources of water in any city, is underground first, through a tap later. This is why borewell water has high amounts of calcium and magnesium. After this, it also travels through pipes before it reaches the tap. All of this adds up to the problem of making water hard.\u00a0<\/span><\/p>\n<p><b>Is hard water harmful?<\/b><span style=\"font-weight: 400;\"> Hard water is not unhealthy. Having said that, experiencing hard water everyday can be irritating to you, to the skin and to your hair. Since hardness isn\u2019t the same as TDS, it\u2019s not necessarily unhealthy.\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_does_a_hard_water_softener_do_How_does_it_work\"><\/span><span style=\"font-weight: 400;\">What does a hard water softener do? How does it work?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">A water softener does one job: it takes the hardness out of your water, so you stop seeing scale everywhere.<\/span><\/p>\n<p><b>How it works:<\/b><span style=\"font-weight: 400;\"> Softeners use a process called ion exchange. Think of it as a swap, and it happens in four steps.<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>The beads:<\/b><span style=\"font-weight: 400;\"> Inside the softener is a tank full of tiny beads. These beads are loaded with sodium.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>The swap:<\/b><span style=\"font-weight: 400;\"> When hard water flows past, the beads grab the calcium and magnesium and give out sodium in return.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>The result:<\/b><span style=\"font-weight: 400;\"> The water that comes out no longer has the calcium and magnesium that cause scale. It\u2019s soft.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>The recharge:<\/b><span style=\"font-weight: 400;\"> After a while, the beads are full and can\u2019t grab any more. The softener then washes them with salty water, which clears out the hardness and loads them with sodium again, ready for the next round.<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">Softeners are usually fitted at the main inlet or the overhead tank, so the whole house gets soft water: the bath, the laundry, the geyser and the kitchen.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">One of the other problems of having hard water at home is that it shortens the life of an RO membrane if you have a water purifier. The scale build-up that the hard water has tends to reduce RO membrane\u2019s life. This is also why a softener becomes helpful, so that you don\u2019t need to keep replacing your purifier\u2019s filters frequently.\u00a0<\/span><\/p>\n<p><b>What it doesn\u2019t do:<\/b><span style=\"font-weight: 400;\"> A softener isn\u2019t a purifier. It swaps ions instead of removing them, so your TDS doesn\u2019t drop much. It doesn\u2019t deal with bacteria and viruses either. Because it adds a little sodium, softened water isn\u2019t meant to replace purified drinking water.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Is_softened_water_the_same_as_RO-treated_water\"><\/span><span style=\"font-weight: 400;\">Is softened water the same as RO-treated water?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">No, though they\u2019re often confused.

But RO is installed at one point, usually in the kitchen, so it won\u2019t save your hair, your clothes or your geyser.\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Are_both_softeners_and_RO_needed\"><\/span><span style=\"font-weight: 400;\">Are both softeners and RO needed?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">It depends on what you want to fix. An RO purifier will suffice if your main concern is making your drinking water healthy. RO removes the TDS. If you want to remove the scale-build up and make your hard water soft, you may have to get a softener, which will do the job for you. RO does not treat water that is used for bathing, washing clothes etc. Only a softener can do that.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In one of the rare situations where your water is very hard, then both are suggested. The scale build-up can also harm an RO membrane which is why using an RO for your drinking water needs and a softener for other purposes helps.\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"DrinkPrimes_purifiers_to_the_rescue\"><\/span><span style=\"font-weight: 400;\">DrinkPrime\u2019s purifiers to the rescue<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Hard water, high TDS and the germs you can\u2019t see all show up together in most metro homes.

What is hard water?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Hard water has a higher concentration of calcium and magnesium than required by your body. <\/span><\/p>\n<p><b>2. Is hard water safe to drink?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Hard water is not exactly unsafe to consume. But, there\u2019s a catch. Your body does need an adequate amount of Calcium and magnesium which, if present in a higher concentration, cause the hardness. If your water is hard, it can have other dissolved solids as well, which warrants the use of RO. <\/span><\/p>\n<p><b>3. How do I know if I have hard water?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">If you find white scales on taps and utensils, if your soap and shampoo don\u2019t lather, if your skin and hair become hard and if your clothes look stiff and dull after washing. <\/span><\/p>\n<p><b>4. What does a water softener do?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">It removes calcium and magnesium through ion exchange, swapping them for sodium, so you don\u2019t get scale and your soap works properly.<\/span><\/p>\n<p><b>5. Does RO remove hardness?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Yes, in your drinking water. RO removes dissolved solids, including calcium and magnesium. But since RO is used for drinking water purposes and not overall usage, RO doesn\u2019t soften your house\u2019s water supply. For that, you need to have hard water softener. <\/span><\/p>\n<p><b>6. Do I need both a softener and an RO purifier?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Not always. RO is enough for drinking water. A softener protects your appliances, skin and hair. In very hard water, many homes use both.<\/span><\/p>\n<p><b>7. Does hard water damage RO purifiers?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Scale can build up on the RO membrane and shorten its life. That\u2019s why some purifiers include an anti-scalant stage.<\/span><\/p>\n<p><b>8. What is an anti-scalant in a water purifier?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">It\u2019s a stage that helps prevent scale from forming inside the purifier. DrinkPrime\u2019s Chennai variant comes with one.<\/span><\/p>\n<p><b>9. Why does the Kolkata variant have an iron remover?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Kolkata\u2019s water is very hard and often carries excess iron as well.
