Hard water, often known as water hardness, is a common water property containing dissolved calcium and magnesium compounds. You might be curious about how hard your water is if you’ve witnessed signs of hard water in your homes, such as soap residue on shower doors, build-up on plumbing fixtures, or trouble lathering.
You might be curious as to what causes water to be hard or soft, whether or not hard water is dangerous, why the concentration of particular minerals causes water to be hard, and how to evaluate water hardness. Therefore, we’ll cover everything you need to know to measure the hardness of water in this blog post.
What Exactly is Hard Water?
Hard water contains dissolved magnesium and calcium. It is measured by the is the quantity of these contaminants present in the water. These contaminants combine with fatty acids in soap to create an insoluble foam that reduces the effectiveness of the soap.
How Is Water Hardness Measured?
High levels of dissolved minerals, primarily calcium and magnesium, in your water supply are usually the cause of hard water. The likelihood of you experiencing hard water difficulties depends on its source. For instance, home-well water users are especially vulnerable to this problem, and thus, measuring water hardness is compulsory. Here are three water hardness tests.
Quick at-home testing
The simplest way to test your water for hardness without going too far is to use a clean, empty bottle, tap water sample, and pure liquid dish soap. Fill one-third of the bottle, add a few drops of pure liquid soap, and shake the bottle ferociously for a couple of seconds.
Hard water will have fluffy bubbles noticeably absent and the water will appear hazy or milky. Soft water will have clear water in the bottom of the bottle and will have a lot of bubbles in it. Use a basic soap devoid of colors, fragrances, and detergents for the best results.
Check with the City
Most towns provide a yearly report with information on the findings of their hard water tests. You’ll know what to expect regarding your home’s water hardness based on your city’s results. Local statistics will provide a solid starting point for understanding water hardness measured in different units, but you must still know how to test it precisely in your home.
A test strip, similar to a test for swimming pool or spa water, is one of the most straightforward procedures. Look for a clean bottle made of glass or plastic with a tight-fitting cap. Straight from the faucet, fill the bottle until it is 1/3 full. after submerging them in the water, examine the color of the paper test strips against the water hardness test kit color chart. The results will show you the hardness level of the water.
You can easily find various water test kits from different brands. They constitute several test strips and a color chart with guidelines to measure the carbonate hardness levels of the water.
Does A TDS Meter Measure Water Hardness?
Are you trying to determine the hardness of your water using your TDS meter? You can’t, that’s for sure! If that wasn’t the response you were searching for, we apologize. Why it won’t function is as follows:
A TDS meter is a tiny, portable instrument used to measure the amount of total dissolved solids (TDS) in a solution, often water. It is a measurement of everything dissolved in your water. A TDS meter measures water’s electrical conductivity and uses this information to calculate the TDS value.
TDS contains much more than hardness, making it challenging to determine hardness with TDS measurements alone. Yes, a significant portion of the TDS will contain hardness minerals when the water is hard, but not all of it. As a result, your TDS measurement will always be much greater than the hardness number.
What Is the Hardness Water Scale?
According to the Water Quality Association, you can measure the hardness of the water in milligrams per liter (mg/L), grains per gallon (gpg), or parts per million (ppm).
Knowing the various water hardness testing scales is essential to understand your test results. Results are in a numerical value indicating the amount of calcium carbonate or calcium carbonate equivalents present in a given water unit. Here is a short reference for the water hardness scale, show results in both mg/L and gpg:
|Grains Per Gallon||MG/L OR PPM||Water Hardness||Effect|
|Below 1||Between 0- 17.1||Soft||None|
|1 to 3.5||Between 17.1 – 60||Slightly Hard||None|
|3.5 to 7||Between 60 and 120||Moderately hard||Dry skin and spotty dishes|
|7 to 10.5||Between 120 and 180||Hard||Clogged pipes and clogged water heater|
|More than 10.5||More than 180||Very hard||Clogged pipes and clogged water heater|
What Is the Best Way to Measure Water Hardness?
One of the best ways to measure water hardness is to refer to professionals. Although there is home testing that people often find the easiest, referring to professionals will ensure accurate results. You should send your water to a reputable water testing lab for the most thorough water hardness analysis.
These companies offer a range of testing, from basic checks to see if your water measures up to EPA drinking requirements, to health checks. These labs use more sophisticated advanced testing kits to determine the number of toxins in your water. The results assist you in deciding whether you need further filtration for your drinking water.
The Bottom Line
Many homes have hard water, which can harm practically anything. However, by testing your water using the three simple procedures outlined above, you can halt the flow of hard water and get rid of it from your home before it causes any damage. Moreover, using water softener also helps you to get rid of hard water problems.
