Home Water Testing Kit Buyers Guide
You can use water testing kits to determine if contaminants are present in your water. In doing so, they can decide if they need to address issues using a water treatment system.
Why Testing Your Home Water is Important
You might believe that you already have clean water and that it doesn’t need testing or treatment. If homes have built-in filters, they might not be doing a good job. For example, filters do help reduce contaminants, but bacteria could still be a problem.
Not only does a home test give you peace of mind, but testing your home water also determines the presence of chemicals and contaminants. A water test helps you understand and adequately address your home’s water issues. A water test also enables you to figure out which treatment you need before using the water.
A water test helps to:
- Identify any problems existing in the home’s water supply.
- You can make sure the water is safe for home use, especially when using a drinking water test kit.
- Create a baseline and track the water’s changes and quality over time
- Determine if the home needs a water treatment system or not
What Does Water Test Kits Test For?
The best water test kits are essential for determining concentrations and levels of specific chemicals and contaminants.
How Do Water Test Kits Work?
You might be new to water test kits and may not understand how they work or what’s available. The first step is understanding that chemistry helps you detect chemicals and contaminants in your water. Many of these water test kits can detect the smallest concentrations. There are several affordable options for those who believe it’s expensive to test their water supply. Not only are these options cost-effective, but they’re also easy to use.
Color Disk Kits
You can find color disk kits available for testing a wide variety of chemicals that help them make sure your drinking water is safe. These tests work by adding a few drops or a powder packet to a water sample in reusable test tubes. After that, the test tubes go into a viewing box.
The viewing box contains a plastic disk that includes color gradients. You must rotate that plastic disk until it matches the water sample’s color. After comparing the color, the next step is reading the chemical’s concentration.
Typically, these water tests occur in several steps and include wait times. Because they have added features, these tests are more expensive and produce more accurate results.
Using a test strip is an affordable and quick way to receive results and peace of mind. However, some of these tests are not as accurate as others. These tests typically include one single-use test strip. These strips change color according to the different contaminants in the water. That means the strips test for the concentration of a specific chemical or pollutant.
Some tests require you to activate the strip. Activating the strip involves dipping the strip into the water sample and swishing it around. Other tests require you to keep the strip underneath a steady stream of water. After waiting for a short period, you can compare the strips to the kit’s color chart.
Hand-Held Digital Devices
Out of these three types of kits, using hand-held digital devices produces the most accurate results. Water testing can occur using colorimeters, digital meters, and photometers. Keep in mind that these tests are also more expensive than their competitors.
You must use batteries and calibration before they begin using these tests. Otherwise, they won’t work. The main reason is that they use an electronic probe that indicates changes in the water to determine which contaminants are present. These devices test the water’s pH levels and various chemicals and pollutants. These contaminants include calcium, chlorides, magnesium, sulfates, and more.

How to Choose the Right Kit for Your Home
Before picking out a test, you must determine how water comes into your homes. Is it coming from a well or city water supply? Or are you testing pool water or water from a furnace? You’ll notice that water test kits are typically for a specific water source. That way, it can test the most common contaminants from that source.
Many water tests can produce results for various common contaminants, including chlorine, copper, iron, lead, and more. Other cost-effective water test kits feature results for one or two different pollutants. Tests producing a broad range of results is the best way to go if you want to determine if a specific contaminant or if several pollutants are in your water.
It’s critical that the water kit tests you’re using produce accurate results. Most, if not all, water test kits tout that they produce accurate results. However, the only way you can know for sure if they read blogger or customer reviews.
While many affordable options produce high-level results, it isn’t a good idea to choose the cheapest test kit. Otherwise, you might find that it has subpar results. You might also find that it doesn’t test for the contaminants for which you need information. It also isn’t necessary to opt for the most expensive professional water test kit. Instead, you should choose one that falls within your budget and tests for the contaminants they need.
When you need to know what’s in your water, or its hardness, picking out the best water test kit is a priority. It isn’t uncommon for a test kit to require lab testing. However, other kits produce immediate water quality results. Before choosing a home water test kit, you need to know your water source. That way, they can determine if they need well water or another type of home water test kit.
