What causes a water softener to experience hardness leakage? 【Basic Knowledge】

The causes of hardness leakage can be divided into four categories! (Water softener)

The water coming out of the softener is unexpectedly hard. This "hardness leakage" can be addressed more quickly if the cause is identified. ■ What is hardness leakage? A water softener uses ion exchange resin to remove calcium and magnesium (hardness components) from water to create soft water. This resin is regenerated with brine and reused, but if there is some malfunction, hardness components can mix with the treated water, resulting in hardness leakage. If left unaddressed, it can cause scale (deposits similar to limescale) in boilers and piping. ■ Causes can be categorized into four main patterns The cause can be identified by the symptoms. 　❶ If the hardness of the treated water is the same as that of the raw water, it may be due to forgetting to regenerate, forgetting to add salt, salt clumping in the salt tank, or clogging in the chemical injection line—indicating that "regeneration is not functioning." 　❷ If it leaks from the beginning, it may be due to water bypassing the resin layer or insufficient salt leading to poor regeneration. 　❸ If it suddenly leaks while the water intake is low, it may be due to poor regeneration, resin washout, or a sudden change in raw water hardness. 　❹ If it leaks gradually, it may be due to resin degradation or the adhesion of iron and silica, indicating "reduction in resin performance." How to identify the cause and proceed with resin replacement and water quality management is explained in this document. Please download the document!
