What is a water test kit?

As the name suggests, a water test kit is an equipment that is used to evaluate the concentration of contaminants in water. As such, it can be used to test your household water, well water or any other type of water out there. You want to check for the concentration of lead, bacteria, nitrates, mercury, etc. a water tester is all you need.

As you know, there are many brands of water test kits out there. They come in different types and varieties. Some are specific for checking a select list of contaminants while others are rather general. Such water testers can be used to check a broad list of contaminants. Even so, there are just some common contaminants that it does an excellent job singling out. So, depending on your needs and expectations, you will have to choose. Be sure to check for the particular set of contaminants your kit is best suited to check.

Do you really need a water test kit?

Like I have mentioned above, thee kits are very beneficial when it comes to checking the quality of your household water. As repetitive as it may sound, these kits are designed to help you decide on an ideal type of water filter or softener. You also get to know the likely contaminants you are dealing with. For instance, detection of lead and mercury in your drinking water should prompt you to do something to get rid of such toxic heavy metals.

Like in my case, out of curiosity, I wanted to know the types of contaminants in my municipal tap water. I was shocked to find out that it actually had high levels of fluoride and chlorine. So I bought a fluoride water filter that doubled as a chlorine filter and had the problem fixed. So, as you can see my water test kit awakened me to a simmering disaster. If you want to take control of your health and the wellbeing of your loved ones, it’s about time bought one of these handy water testers.
