Drinking high-hardness water for a long time can cause cardiovascular, nervous, urinary and hematopoietic diseases.

Boiling water has poor taste and often causes scaling at the bottom of the pot, which seriously affects the taste and quality of food.

Hair and skin often have a dry, tight feeling when bathing, which injures the skin and accelerates aging.

Washing clothes wastes detergent and the clothes are not easy to wash at the same time the clothes after washing are not easy to clean. It is brittle and hard with the smell of detergent remaining. Water stains and spots often appear on tableware and sanitary ware, which need to be cleaned frequently, and scales appear on pools and even walls. The thermal efficiency of water heaters decreases with the increase of using time which is also due to the increase of accumulated scales, which not only wastes energy (power consumption), but also forms a potential safety hazard.

However, not all hard water will precipitate scales after boiling, because calcium and magnesium ions may also exist in the form of sulfate or chloride. This kind of hard water is called permanent hard water. That is to say, you can't remove calcium and magnesium ions by domestic means. The hard water caused by bicarbonate mentioned above is called temporary hard water.

So we can use water softening machine for scale removal and spare parts Multifunctional Control Valve for sand filter and actived carbon filter.
