First, let’s clarify the meaning of hard water: what does it actually mean? What makes it “hard”? The definition is simple: in contrast with “soft water”, hard water is a water that is rich in minerals. That is, it contains calcium and magnesium in high concentrations. Apart from these, hardness can be caused by other elements, too. These include aluminium, barium, strontium, iron, zinc and manganese. The presence of all these elements begs the question whether hard water is safe to drink.

The minerals present in this type of water are capable to dissolve, and may become difficult to be identified by the naked eye. The good news is, however, that we do not have to be chemists or specialists to notice if our water is hard, because over-mineralisation can cause a number of problems in our home.

One of the easiest ways to tell is by examining its effects on the equipment in our house. It can cause staining, fogginess and spots on glasses that are difficult to remove even after repeated attempts. Look at the plumbing system in your house: do the showers, bathtubs and faucets have mineral deposits and scale? Are your boilers becoming less effective or clogged? After taking a shower, is your skin downright itchy, dry, your hair sticky and dull? Look at your wardrobe, are your white-coloured clothes losing their radiant white and turning greyish or faded? If the answer is yes to most of these questions, you’re probably dealing with the effects of hard water.

These unpleasant effects pose several considerations concerning the safety and healthiness of drinking this type of water.

There are no conclusive scientific evidence that hard water used for drinking can cause negative effects on our health. Although it is considered harmless by WHO, and it has no apparent adverse health effects, the taste may still be unpleasant to some homeowners. The calcium and magnesium present in hard water are essential nutrients that contribute to proper body functions. However, it is not advisable for people who have heart or circulatory problems, or who are on low sodium diets.

The most serious problem caused by water hardness can be noticed on our equipment like our dishwasher, washing machine or other appliances that handle water, which may break down or fail to function properly. This is why we recommend you to use water softeners to reduce the formation or get rid of of lime scale deposits in kettles, water heaters or other kitchen appliances. Protect your equipment with a great variety of water softeners that range from traditional solutions to liquid water softeners like the Acqua Brevetti MiniDUE Liquid Water Softener, which you can all find on our web shop.

For best results in terms of drinking water quality, we recommend using water softeners together with a water filter that will get rid of any potentially harmful impurities in your tap water.
