Water Hardness Scale: How to Test Water Hardness


Water hardness refers to the amount of dissolved minerals, particularly calcium and magnesium, present in water. The level of hardness can vary depending on location, and it can have an impact on various household appliances, such as dishwashers, washing machines, and water heaters. If you suspect your water is hard, testing the water hardness is a straightforward process. In this blog, we'll explore the water hardness scale and the methods to test water hardness.


The Water Hardness Scale

Water hardness is measured on a scale of milligrams per liter (mg/L) or parts per million (ppm). The scale ranges from 0 to over 400 ppm, and it is typically categorized as follows:

Hardness Scale

  • Soft: Less than 60 ppm
  • Slightly hard: 61-120 ppm
  • Moderately hard: 121-180 ppm
  • Hard: 181-250 ppm
  • Very hard: Over 250 ppm

The level of hardness is generally determined by the amount of dissolved calcium and magnesium minerals in the water. These minerals can be detected using various testing methods.

Testing Water Hardness:

  1. Test Strips: Test strips are a popular and affordable method for testing water hardness. Simply dip the strip into a sample of water, and the strip will change color to indicate the level of hardness. Follow the instructions on the packaging carefully, as the test strips can vary by brand.
  2. Liquid Test Kit: A liquid test kit is another option for testing water hardness. These kits contain reagents that react with the minerals in the water to determine the level of hardness. Follow the instructions on the kit carefully, as the process can vary by brand.
  3. Electronic Tester: Electronic testers are another option for testing water hardness. These devices use an electrode to measure the electrical conductivity of the water, which correlates to the level of hardness. While these testers are more expensive than other methods, they offer precise results.

Conclusion

Testing water hardness is an essential step in maintaining household appliances and ensuring clean, safe drinking water. Knowing the level of water hardness can also help you choose the best water treatment system for your home. If you suspect your water is hard, use one of the methods described above to test your water hardness, find out what system meets your exact needs by calling your local EcoWater Systems expert today to find out ways of softening water
