Express test with soap. Pour about 300-400 ml of water with a transparent bottle and add 10 drops of liquid soap. After that, shake the bottle and pay attention to the foam. If there is too much, the water is soft. If there is too little bubble or disappears quickly, the water is difficult.
White Raid and Points. This is also a sign of hard water. Such deposits can occur in the fabric even after washing, even after washing.
Hair and Skin Test. If the skin becomes tight and dry after the shower, if the hair becomes hard and dull, the shampoo is washed and foamed rapidly, then the problem is hard water.
Use test strips. This will help to determine the hardness of the water more accurately.
Objection to Vodokanal. Also one of the options. Request reports from your company: They usually show the hardness of water.
