Have you noticed white scales on your sink, shower or bathtub? Or even your glassware with white spots that look so unclean but no amount of extra washing clear it out. Also, your new t-shirt doesn’t take much time to turn into a dull old one. If these types of stain are common at your home then you can conclude that your water is hard. To avoid hard water from ruining your clothes and other home items where there is water contact, you should immediately look for water softeners at your local market or online. But don’t forget to check more water softener reviews on Home Fascination before investing in one.
But what is the hardness of water?
When the mineral content of water is high, it can be considered as hard water. There can be two types of hardness:
Temporary hardness- Bicarbonate minerals mainly calcium and magnesium bicarbonates precipitate in high temperature and form solid deposits in the container. They can be removed by boiling of water.
Permanent hardness- Sulphate minerals like calcium and magnesium sulfates contribute to permanent hardness. They cannot by simple boiling. They require proper water softening system for the task. Go through water softener reviews online or ask people who are using it and find a suitable water softener for your home.
How to measure water hardness?
Below given are the 5 easy ways of detecting and measuring the hardness of the water. Read on to find out how you can do it at home.
#1: Soap water test
This is the easiest and least expensive method out of all that is used to find out if the water is hard. Fill a 400ml bottle with 360 ml of tap water (12 ounces) from your home. Add 10 drops of liquid soap, close the container and shake well. Now open the lid or cap and observe the sud formation. If there are lot of bubbles oozing out, then the water is soft. But if you see only a few bubbles then add more soap and shake again. You will notice the water containing white suspended particles making it cloudy. This is due to scum formation. This happens only in hard water. If the water would have been soft then instead of cloudy, there would have been clear water and the sud floating on the surface.
#2: Hardness testing kit with Tablets
These test kits can be bought from the market. After adding the reagents as per instructions, 1 tablet is added in the sample water. If it turns red, water is hard and it will turn blue or green if the water is soft.
#3: Test Strips
Test strips are available in the market along with a scale that contains a spectrum of colors. Just like Ph strip is used to determine the amount of acidity in a solution, these test strips can be used for measuring hardness in a similar manner. Add a few drops of your sample water on the strip or you can dip the strip instead. The strip will develop a color. Now match it with the color scale provided along with the kit to determine the concentration.
#4: TDS meter
TDS stands for total dissolved solid. This device might cost a bit of fortune but it can easily determine the amount of all the dissolved solids in water very accurately.
#5: Electronic Colorimeter
Like TDS meter, a colorimeter is a small portable electronic device to determine the exact hardness of water. It uses a different principle for the task. It will determine the hardness by measuring the absorbance of light by water sample which is then compared to a standard value for the particular wavelength of light emitted.
Use any of these methods and measure the hardness of the water supply at your home.
