Water softening systems from Swisskalk

What is a water softening system?

Hard water can cause a variety of problems in your home. But what exactly is hard water, and why should you care about it?

A water softening system reduces the calcium and magnesium content in your water. These minerals are responsible for limescale buildup, which can damage your pipes, household appliances, and even your skin.

At Swisskalk, we are dedicated to providing the best solutions for your water-related problems. We understand how important clean and soft water is for your home.

The cost of a water softening system can vary depending on the size and type of system. Prices typically range from CHF 2,000 to CHF 2,600, depending on specific conditions. Installation costs by a plumbing professional may vary. At Swisskalk, we offer various models tailored to the specific needs of our customers.

Setting the correct water hardness is important for maintaining both your household appliances and overall water quality. Water softening systems use the ion exchange process to replace calcium and magnesium ions with sodium ions, resulting in softer water. One important factor to consider is the sodium content in the water: for every °dH (degree of hardness) reduced, the sodium level increases by approximately 8 mg/l.

Since the sodium content in municipal drinking water is generally quite low, a moderate reduction in water hardness poses no issue. The legal limit for sodium is 200 mg/l, so even after softening, the sodium level remains within safe limits.

To find the optimal balance between sodium content and water hardness, the initial values must be known. For example: if municipal water has a sodium content of 40 mg/l and a hardness of 20 °dH, and you wish to reduce it to 5 °dH, the sodium level would increase by 120 mg/l (15 × 8 mg/l), resulting in a total of 160 mg/l — still below the legal limit. By adjusting the blending ratio per °dH, the sodium content can also be slightly reduced. This way, the water remains soft, safe, and pleasant — while protecting your plastic and stainless-steel pipes.
