The Best Water Testing Kits: Find Out Exactly What Is in Your Water

It would be great if we could safely drink the tap water in our home but this probably isn’t possible without some water testing kits. It’s even unimaginable to use untested tap water for the plants. So, drinking it for ourselves is certainly out of the question.

A water testing kit can provide numerous benefits. It can detect the water contaminant that might be in your tap water, well water, pool, or any other source. This eliminates the need to pay top dollar for professional consultation.

Plus, these water testing kits will help determine just what contaminants are lurking in your water. No waiting for lab test results; you get to know the problem and start working on it almost immediately.

It’s not hard to use a water testing kit on your own. The instructions are usually clear. That’s why you don’t have to worry about any complications.

Curious about these kits yet?

Let’s discuss them further below.

How Do Water Testing Kits Work and What Do They Test?

If this is the first time you’re hearing about water testing kits, you’d probably have this question in mind, “how do they work?”

Fortunately, modern chemistry now gives you the ability to test any kind of water without having to rely on a laboratory.

As you conduct these tests, the kit will show the chemicals that are present in your water. This even includes the substances that are only present in minuscule concentrations.

Thankfully, these water testing kits don’t cost an arm and leg either. With the right kit on hand, you can quickly check whether your pool water is safe to swim in or if your tap water/well water is suitable for drinking.

The contaminants that these water testing kits can detect include bacteria, iron, pesticides, nitrite, nitrate, chlorine, lead, etc. They also check the pH level, alkalinity, and hardness of the water.

The functionality of these tests depends on what kind you use. Let’s discuss these separately now:

Color disk kits

Color disk water testing kits work when you add a powder and some water to a reusable tube. You can then put the tube in a viewing box, which has a plastic disk with a color gradient.

When you rotate this disk, you can find the part that matches the sample. After that, it’s a matter of seconds to check what concentration of the chemical that particular shade means.

Disk tests are usually a bit complicated, which also makes them more costly than other options. However, they have the advantage of being more accurate.

Test strips

These strips are an affordable option for testing water. They’re single-use strips that can change color when dipped in water. The resulting color indicates what chemicals are present within the liquid.

There should be a color card in the packaging for the test strips as well. Once you’ve waited long enough after dipping the strip in the sample, it should be possible to match the color to the chart.

Hand-held digital instruments

Digital devices might give you the most accurate results of all. However, these are also the most expensive option and require both batteries plus correct calibration.

How to Choose a Water Testing Kit

Though you can install the right shower head to protect your hair and skin from hard water, you’ll need to go a step further when it comes to drinking water that’s free of harmful minerals. That’s when you should choose the water testing kit that fulfills your need.

With the various options out there, it can be challenging to choose a specific water testing kit. The following factors will help you decide:

Know the source of water

The first consideration is the kind of water you want to test. Most water testing kits are formulated and designed for specific water sources.

For instance, a kit for testing well water might be different from one that tests a public water supply.

The kits will test for the common contaminants in that specific source of water. Before you place any orders, make sure your kind of water is mentioned in the description.

Finding out about the testing method

Water testing kits take different time periods to show a result. If you’re not too concerned about time, you may settle for a kit that takes longer but is more accurate.

If you’re in a hurry, though, you should go for the at-home kits.

Know your requirements

If you just want to test for a couple of contaminants instead of every single substance in your water, a less expensive test might do.

A more expensive option will give you a whole list of possible contaminants. So, you can reassess what you need.
