Testing water hardness is important to test the contents of water. Dealing with hard water problems in the home can be a nuisance. By testing water hardness, you can know the amount of hardness minerals in water that can affect the amount of soap and detergent necessary for cleaning.
Hard water is water that has high mineral content. Testing water hardness allows you to see the level of the minerals primarily consist of calcium, magnesium, metal cations, and sometimes other dissolved compounds such as bicarbonates and sulfates.
Calcium usually enters the water as either calcium carbonate in the form of limestone and chalk, or calcium sulfate in the form of other mineral deposits. Hard water is generally not harmful to one’s health, but testing water hardness is still important to get a good quality of bathing and clothes washing.
Hard water causes scaling, which is the left-over mineral deposits that are formed after the hard water had evaporated. This is also known as limescale. The scale can clog pipes, ruin water heaters, coat the insides of tea and coffee pots, and decrease the life of toilet flushing units. If you do not want to find the water you use in such condition, testing water hardness is suggested.
Water hardness is measured in “grains” per gallon, in milligrams of calcium (Ca) per liter, or parts per million. To know the measurement, you ca take a water sample to a water test lab to have its hardness measures. The good news is testing water hardness can be done at home.
By testing water hardness, you will find whether the water has temporary hardness or permanent hardness. Temporary hardness is caused by a combination of calcium ions and bicarbonate ions in the water. It can be removed by boiling the water or by the addition of lime.
On the other hand, permanent hardness is hardness that cannot be removed by boiling. It is usually caused by the presence in the water of calcium and magnesium sulfates and/or chlorides which become more soluble as the temperature rises. It can be removed by using a water softener or ion exchange column.
A wide selection of water hardness testers is available on markets. You can choose one based on your budget and needs. Actually, they all are affordable, and each offers high quality features. No matter what the water hardness testers that you choose, they will really help you in testing water hardness.
If you have a problematic level of hard water in home but you cannot purchase a water hardness tester, you can try a traditional way of testing water hardness. Open your tap water faucet and fill up a bottle having a cap with about a half-cup of water and add 10 drops of dish water detergent. Then, shake it well.
Testing water hardness this way gives you three results possible. If the soapy solution foams up quickly, the water is not hard. If it does not foal up but instead creates a milk-curd-like or soapy film on the water, the water is likely hard. Then, if you have hard water scale build-up on your shower door or white scale on your faucet aerator, it indicates that your water is too hard.
