What Is the Problem With Hard Water?

Water is one of the most widely used commodities in the world, widely used for a large number of applications like washing, cleaning, drinking, The water is available from a large number of natural and other sources, like rainfall, rivers, waterfalls, wells, lakes, ponds. However the quality of the water is not uniform, there are many variations in the quality of water, depending on the dissolved minerals and other chemicals. Rainfall is the purest form of water naturally, while water in other forms may contain dissolved chemicals in amounts which may vary, and is called hard water if the minerals in the water are significant.


Hard water usually contains dissolved calcium sulfate and magnesium sulfate, though it may contain other minerals also. Some of the problems caused by this water are:

  • Does not have the sweet taste of normal pure water.
  • Leaves a film when used for washing hands, and the body makes it difficult to wash the oil from the hair
  • Can cause damage, and leave the clothes grey when used for washing clothes
  • Leaves a deposit on the walls of the pipes and other plumbing accessories over a period of time.
  • Increases the amount of electricity required for heating applications, and may block the plumbing system


The water which is supplied from the water mains by the government is usually treated to remove minerals like calcium, magnesium, and iron and is fairly pure. However, in many areas, people rely on water from local sources like the well or pond in their area. While this water may not be used for drinking, it is used for other purposes like washing, cleaning. The soil in the area may contain many minerals, and some of these minerals are dissolved in the water which is exposed to the minerals depending on the chemical characteristics of the minerals.


One of the main reasons why using hard water is so risky, is because of the deposits caused by the hard water. As the water passes through the plumbing system, especially the pipes. Some of the minerals in the water get undissolved and deposited on the walls of the pipes, faucets and other parts of the system. Due to this the area available for the water to flow decreases, so the flow rate in the pipe reduces, increasing the time taken to get a specific amount of water. Over a period of time, the deposits can completely block the piping system, and no water will be delivered, though there is no problem with the water supply.

Water heating

The water with dissolved minerals can also cause major problems while heating the water. Due to evaporation, the minerals will get deposited in the heater, and energy will be wasted to heat the minerals. This can greatly increase the electricity or energy bill and also damage the geyser and heating equipment.

Treating hard water

There are many methods available for treating hard water, and a particular method should be chosen depending on the volume of water treated and how it will be used. It is advisable to check the various Water Softener reviews available online, before finalizing the best method for softening the water. While water containing minerals can be used for gardening, and outdoor washing, for other applications, it is advisable to soften the water.
