If the water contains high amounts of calcium and magnesium ions it’s considered to be hard water.
Some other metal ions such as those of aluminum barium iron manganese strontium and zinc also contribute to the hardness of the water.
These ions are found in water in the form of carbonate bicarbonates sulfates and chlorides.
Another way to tell if water is hard is if it doesn’t form lather well.
This failure to lather is due to the reaction between calcium and magnesium ions and soap molecules.
The resulting molecules are insoluble in water and remain at the surface.
Fewer soap molecules mean less lather.
When rain falls to earth it percolates underground during this process.
If rainwater comes across deposits of limestone chalk or gypsum which are made up largely of calcium and magnesium compounds.
These metal compounds pass into the water causing it to become hard.
Hard water is generally not a health risk but it is a nuisance.
When hard water is heated a certain amount of water evaporates causing the minerals suspended in it to precipitate.
These residues can then accumulate inside pipes, water heaters, washing machines, and dishwashers.
The result is reduced water flow or blockages stress on pipes and fixtures, spots on glasses and dishes cleaned in a dishwasher, and less effective clothes washing due to a lack of suds.
According to the world health organization water containing calcium carbonate at concentrations below 60 milligrams per liter is generally considered to be soft, 60 to 120 milligrams per liter is moderately hard, 120 to 180 milligrams per liter is hard, and water with more than 180 milligrams per liter of calcium carbonate is very hard.
Hardness caused by the presence of just calcium and magnesium carbonates and bicarbonates is called temporary hardness and can be removed by boiling the water and then filtering it.
On the other hand, if water hardness is due to the presence of calcium and magnesium sulfates and chlorides, it’s known as permanent hardness and can’t be eliminated by boiling.
Removing permanent hardness requires special chemical methods such as soda treatment, cleans method, ion exchange, or the resin method
Knowing Your Water Hardness
After experiencing the signs of hard water in your home you’ll want to fix this troublesome problem and fast.
The best way to get started is to learn just how hard your water is.
There are a couple of different ways to do this.
One fast way is to check with your city.
Your water quality report tells you where your water comes from and what’s in it.
Along with a lot of other information.
Some include your areas and hard water number.
Keep in mind that this report provides a high-level look at the water in your general area but it’s not specific to your home.
A simple way to check for hard water can be performed with a clean empty bottle and pure liquid soap like Castile.
Pure liquid soap doesn’t contain additional additives that will create suds even in hard water.
Fill one-third of the bottle with water from your tap add a few drops of soap and shake.
If you have soft water the results will look something like this.
If your water is hard it will look something like this.
while this test shows if you have hard water it doesn’t tell you how hard the water in your home is.
To get that number, you need a hard water test kit.
You can purchase one at your local home improvement store or order a free kit at homewater101.com.
It includes everything you need and it’s easy to do.
Simply fill a glass with cold water for your bathroom sink.
Dip the test strip in for 3 to 5 seconds and then remove it compare the color on your strip to the chart and that will give you your hardness level in grains per gallon.
Now you’ll know exactly how hard your water is.
Knowing your specific number will help you find the perfect softener for your home.
