Water Test Kits Buyer’s Guide


If you haven’t figured it out yet, let us break it down to you: there’s a saturated market out there for water test kits. Thus, if you’re shopping for the best water test kit for your home, you’re bound to be confused and overwhelmed.

Let us walk you through the process of choosing the best well water test kit for your home. In this guide, we’ll discuss the things you need to factor when buying a testing kit for drinking, pool, or well water.

Parameters

First of all, you need to check how many parameters the test kit detects. For instance, some tests only detect hard metals, while others check for bacterial and pesticide concentrations in your home water.

As the number of parameters increases, the price does too. However, you should consider spending a few extra bucks to check for multiple contaminants in your water.

Testing Process

Also, you can choose the water test kit according to the testing process. Most tests are strip-based, as they are easier to use for most homeowners. Also, there are some vial-based tests that involve multiple tubes for checking different contaminants.

Also, the more expensive tests are lab-based. You have to send an indication to the labs, and they will email you the results in a week or so.

Depending on how long you’re willing to wait to get the results and how much you can pay for a test, you can choose the water test accordingly. For instance, if you want instant results, you should use strips as they give results in a few seconds.

However, if you’re willing to wait for a few days to get instant results, you can opt for the lab-based tests as they are very accurate and test for up to 200 parameters.

Water Source

Along with checking for parameters, you also have to determine where the test is made for. Is it suitable for checking pool water quality? Or, can you only use it to check the water quality of your faucet?

If you want a water test kit for multiple purposes, make sure that you choose accordingly. Otherwise, you’ll have to buy different tests for different areas.


Frequently Asked Questions


Here are some frequently asked questions to help you resolve queries in your mind about water test kits

Checking the quality of your drinking and well water is very important as it indicates if you need a filter. If you are drinking unclean and unsafe water, it can be extremely hazardous to your health.

Plus, it ruins the finish and longevity of your pipes and alters the water quality for laundry.

According to the EPA, you should test the water in your home at least once every year. However, if your water appears dirty, you can check multiple times a year.

In some cases, the color you get as a result might not match any color on the color code. It means that the test is sub-par, or you haven’t followed the instructions properly.

Do the test again and see if there’s a difference in the results. Otherwise, you should buy another water test kit and check again.


How Do Water Test Kits Work?


Home water test kits are very easy to use as they are built for DIY purposes. Thus, you won’t have a hard time checking the quality of water in your home.

Depending on the type of the water test kit, the working mechanism can be quite different.

If you’re using strip tests, you have to dip the strip into the source of water. The strip will change color depending on the number of contaminants in the water. Then, compare the color on the strip to the color code that is present in the product packaging.

This will show you which contaminant is present in the water source.

Another way to test water quality is by using vials. In these tests, you’ll have different vials for checking different parameters. You have to put a few drops of water in each vial to check the color change.

If something is present in the water, it will change color, indicating that the water is contaminated. You can check the results according to the instructions on the packaging.


Benefits of Water Testing


Water testing is not only beneficial for your family’s health but also for your appliances and the water pipes in the house. Clean and safe water is the ultimate way to ensure your family’s health.

Good for Health

The major benefit of water testing is that it is good for your health. According to the CDC, you should drink eight glasses of water every day. But what if this water is contaminated?

This means you’ll be taking in harmful bacteria and heavy metals that can cause many diseases. Poor water quality is associated with hepatitis A, Shigella, and norovirus. If you want to protect yourself and your family from these diseases, make sure you check the water quality.

Also, contaminated water is harmful to your skin. If you’re showering with water containing heavy metals, it can affect your skin and may even lead to skin conditions.

If these heavy metals are present in drinking water, they can pose a serious threat to your health. Research has shown that arsenic in drinking water is associated with blood vessel damage, nerve, and heart conditions.

With so many harms of unclean water, you must test the water’s quality to ensure that your family is only getting the cleanest water.

Safe for Appliances

Along with being safe for your body, clean water is also important for your appliances. Studies have shown that hard water can reduce the lifespan of appliances such as the dishwasher and washing machine.

If you want your appliances to last long, make sure to check the water quality and take the necessary steps to remove the contaminants.

Also, if you use soft water in the dishwasher, it can give you the same cleaning results as using hard water. But here’s the catch: the former takes half the amount of detergent as the latter.

Moreover, mineral deposits from hard water can ruin the appearance and performance of the appliances. If the water coming through your kitchen faucets is hard, it will leave mineral deposits on the sink, making it seem scaly.

As you can see, water testing can help you increase your appliances’ longevity and reduce the cost of maintenance. When you make a new house, you’ll get the free water test kit for the first time. After that, you’ll have to test the water yourself annually.


Types of Water Testing Kits


As clear from our reviews, there are different types of water testing kits that you can use for testing the water quality at home. All these kits are very easy to use and read.

Let’s discuss these types in detail to help you decide on the best water kit for your home.

Vials

Vial-based tests, as the name indicates, come with vials. You get differently colored vials to check the concentration and presence of different contaminants. For example, if a test can check five parameters, it will have five vials.

You have to put a few drops of the water from your faucet or the pool in each faucet. If the color changes, it means that the particular contaminant is present in the water.

Some tests have different checking mechanisms, but you can learn more about them by reading the instructions manual.

Strips

Possibly the most common kind of water test kits are strip-based. The strips are sort of like the litmus test you did in school. As you dip the strip in the water, it changes color according to the contamination present in the water.

In such tests, you also get a color code along with the strips. When the color changes, you have to compare it to the color code to determine which contaminant is present in the sample.

Also, in some tests, the color intensity indicates how much of that contaminant is present in the water.

Lab-Based

For these tests, you just need to buy the product as the lab charges are covered in the price. You will get the results in about 7 to 10 days for such tests as they are lab-based.

A significant advantage of using lab-based tests is that they detect the presence of hundreds of contaminants. For instance, the  Safe Home ULTIMATE Drinking Water Test Kit can test for up to 200 parameters.

However, these tests cost more as complicated processes, experts, and machinery are involved.


Final Words


To sum it up, we’ll say that testing the quality of water in your home water is of utmost importance. You should do it at least once a year, if not more than that.

Whether you want to use strip tests or vial tests, you’ll find an option in our list of the best water test kits. You can also use our buyer’s guide to find the best water test kit for your home.
