The white scale and spots are caused by hard water. The hard water includes calcium and magnesium so it remains when water is evaporated. The calcium and magnesium have the characteristic that they tend to stick on materials, so white scale remains on faucets, bath tabs, sink, and so on.
How to remove the calcium and magnesium? The solution is to install a water softener.
How Water Softener Works?
Each water softener has an ion exchange system. The ion exchange means that calcium and magnesium are exchanged into sodium. The water softener has resins in its tank. The resins absorb calcium and magnesium and release sodium when water passes through the water softener tank. When the resins hold calcium and magnesium fully, they are no longer catch them. At this timing, the water softener’s valve takes concentrated saltwater from its brine tank and the saltwater is absorbed on the resins and the calcium and magnesium are released. This process is called regeneration.
How to Test Water Hardness
To select the right size of the water softener, you need to test water hardness first. you can buy the test kits online and test it by yourself. The Youtube video explains how to use it. Also, you can ask us to test it for free. If you need it, please call or contact us anytime.
How to Select the Right Size of Water Softener?
Once you find your water hardness, read the chart to find the right size of the water softener for your house. For example, if you find that the water hardness is 27 grains per gallon in the chart and you have 3 people in your household, the right size of the water softener is 45,000 grains.
