Best Water Test Kits – Buyers’ Guide

What do They Usually Contain?

A testing kit uses a sample of your water to determine how safe or dangerous it is for consumption. However, it’s vital to add that when buying a testing kit, there are many things one must look out for, depending on the contaminant you wish to experiment on. Some of the pollutants that are usually tested for include bacterial viruses, cryptosporidium, cysts, and much more. These chemicals and substances are hazardous and can lead to the contraction of various water-borne diseases. The use of a kit will go a long way to allow you to identify the best filtration methods you can employ, as well as how best your water can be utilized.

Additionally, it’s also worth noting that a typical test kit comes with strips which have been designed to contain reactants that change color when exposed to specific contaminants in your water. Others include a color wheel, which is then compared to your water sample after it reacted with the test kit’s reactant substance. Different colors represent the various contaminants available.

What are the Different Types of Test Kits?

There are three significant kinds of test strips available in today’s market, with each one of them owning special features that set them apart from the other. The three types include test strips, color disk kits, and the digital test strips. In the following sections, we discuss each type into detail and teach users which ones are more effective, less expensive, and more durable.

  • Test strips

The easiest to use, most common and affordable type of water test kit is the test strip. These test kits don’t have a 100% accuracy, but they do offer a good idea of the quality of your water. What’s more, they are easy to use and require that you simply dip the strip into a small sample of water, and gently shake the tube. The color change that happens shortly after can then be compared to the included color chart to find which contaminant is present in the water.

  • Color Disk Kits

When compared to the other available methods, the color disk testing kits offer the most accurate results when used. These kits come with a tube that holds your test powder which is where a few drops of your water sample will be placed for the experiment to proceed. Another means of experimenting is to pour the powder into your water sample. This should be followed by mild shaking, to ensure that all contents mix very well. Your tube is now ready to be placed in a plastic viewing box, and the color will then be compared to those available on the color disk included in the kit which helps to determine the concentration of any chemical present.

  • Digital Test Strips

The digital test strip is the most recommended and trustworthy water test strip in the market today. It is considered the most accurate and comes in a small hand meter, photometer, and colorimeter design. The accuracy of this testing kit comes at a considerable cost, however. The digital test kit is seen as the most expensive on the market. Furthermore, operating this unit is simple and requires a couple of calibrated batteries. These kits are lightweight, compact, reusable, portable, and also very reliable.

How do I Determine Which Product is Most Suitable for Me?

Having a clear picture of what you want means you’re aware of all the features and design factors that come together to make this testing kit a reality. In finding the perfect package for your household, there are significant considerations to be made before making a purchase.

  • Cost

This relates to the price of the kit, as well as your budget. In many cases, expensive features are associated with high quality, while cheap ideas are considered items of low quality. This is the case in some instances, but it doesn’t always happen. As much as possible, you’re advised to create a budget and stick to it, no matter what. Be sure to compare and contrast all available products within your budget, to find one that works well for your home. Going in for a product based on price might leave you with something that isn’t very effective in operations.

  • Additional Uses

As stated, there are different kinds of testing kits. Some kits are simply made up of a bunch of different kits. The number of different testing kits within a single package determines how many contaminants that can be tested for. You will get a more transparent result if you go in for a test kit that can check ammonia, calcium, lead, magnesium, and many other chemical levels in your water. Choosing a product with options offers you more value for your money by allowing you to test for many different chemicals at the same time.

  • Accuracy

The effectiveness, ease of use, and reliability of your water testing kit determine how awesome it’ll be in operation. There are kits with the ability to read all kinds of contaminants present in your water, even if they’re over 150. Most of these kits are also very user-friendly as they don’t require any particular scientific background. The efficiency of every testing kit is also determined by time. Some kits may require a laboratory setup, while others can produce test results within a couple of hours.

What are Some Advantages of Having a Water Test Kit?

It is highly beneficial for many reasons, some of which include;

  • The presence and concentration of the various contaminants in your water are displayed through the undertaking of a water test kit. Having such information can go a long way to help you decide whether or not you need a water filter, as well as which filter type to invest in.
  • Another benefit that comes with these kits is that they show you if there are any heavy metals in your water, including their concentration. Using them for this allows you to change the water within your pool or aquarium as and when you find it necessary.
  • Drinking pure water is a necessity if you wish to avoid contracting water-borne diseases like cholera and dysentery. When you test the water with these kits, you get to make sure that every drop you consume is very pure. This offers you peace of mind, knowing that the water you’re drinking has no hazardous effects.
  • The final benefit derived from using it is the ability to check for the hardness and softness of water. Hard water can damage your appliances, clothes, and even your body; thus knowing the state of your water will help prevent harm from coming your way. These are but a few of the benefits we derive from making use of kits.

What do They Normally Test for?

There are different types of tests; no matter how complicated or straightforward their design is, they are all created with one main goal – to detect all the different contaminants in your water, such that you can take the appropriate measures to remain safe.

Some of the contaminants test kits typically recognize include alkalinity, iron, nitrite, nitrate, bacteria, and hardness of the water. There are many others that these tests also identify, and each one increases the number of benefits offered by water test kits.

Water Test Kits – FAQs

Why do I Need to Test my Water?

We all consume water daily for its numerous benefits. Water helps us with many things besides quenching our thirst. It is used for cooking, laundry, cleaning, and many other activities that help make life easier. A more significant percentage of the earth’s water is contaminated, and this poses a lot of health issues for all humans. To ensure that the liquid you’re ingesting is free from dirt and debris, you need to be aware of its chemical composition.

The best way to know this is via the use of water testing kits. These kits help you to find out if there is a contaminant in your water or not. They help prevent the occurrence of water-borne disease within your household, which keeps you healthier for longer.

How do I Accurately Determine if my Water is Contaminated or Dangerous?

The level of contamination or danger in your water is determined whenever you use a water testing kit. The kit you choose will determine the chemical composition of your pool. There are some models that require a laboratory setting, while others can be used within the comfort of your home. The home tests are available in many different types, too; thus, you can use any of them to find out precisely what is in your water in record time.

How Often Should I Test My Water?

Testing your water and the frequency of testing will depend on the source of water. For example, many wells in the USA are tested immediately after they’re constructed. Subsequent testing sessions are handed over to the owner of the property. The EPA then conducts a test annually, to ensure that all microorganisms living in your water are duly removed.

The presence of harmful chemicals and elemental contaminants should be tested every two to three years. The final time where a test will be essential is after any natural disaster such as an earthquake or flooding. In order not to forget the next testing session, homeowners are advised to keep a calendar or test schedule, available at all times.

Are Test Strips Reliable?

The reliability of a product is primarily determined by how it’s manufactured. This stays true for water testing kits around the world. Currently, there are thousands of test kits available in the world, with only a handful of them being very accurate. According to scientists and users themselves, the reliability of a water test kit is mostly dependent on how it was created, and the type of equipment it is. There are three major test kit types in today’s market, and each model is designed differently.

The first water test kit type is the strip, which some may refer to as the most common. Even though it is cheaper than the other two, we can hardly call it inaccurate. The water test strips, when compared to the different types of testing kits, offer a less accurate testing scale, which will provide you with something more precise than a ballpark figure.

The second type of water testing kits is the liquid test kit. This is the second type and a slightly more accurate option for all households. It is also very cost-efficient; thus, we believe it is worth the buck.

The final and most accurate test kit in the market today is the scientific meters or kits. These are guided electronically; thus, they offer you an exact output. This, however, comes at a high cost. If absolute quality is what you seek, no matter the price, we will recommend that you opt for the accurate meters.

Do Test Kits Expire or Go Bad?

Like every other product, your kit can and will go wrong, even when it’s not been used. Many of these kits are designed to expire; thus, the manufacturers often place the expiry date somewhere on the packaging. The expiration date sticker is very easy to see, and it must be adhered to if you wish to have the best, authentic results at all times.

Once it has passed its expiration date, it is advised that you invest in a newer one, to reap all the benefits of using a test kit. Expired test kits can give off wrong readings which may affect your health or that of your family.

What Are Some Signs that could Mean that I Should get my Water Tested?

In some instances, it can be effortless for you to identify that it’s time for a water test. There are numerous signs your water can show you physically, to help you know when and what to test for. In this section of our article, we pay direct attention to the signs or traits visible in the water, and how they determine whether or not a test is required.

The significant ways through which we know that water needs analysis is via a change in color, taste, or odor. Other traits include the water staining your clothes or plumbing fixtures. All these are signs of a problem; thus, the need for a test.

In other cases, you may not come across any physical signs. Instead, you will focus on the location of your water sources and its proximity to other elements such as septic tanks, highways, industrial areas, and many more. The composition of your home’s plumbing materials can also go a long way to determine your need for water testing.

How Should I Store my Test Kit/Test Strips?

Storage is vital for the longevity of all products, whether it is edible or not. Several products have their shelf life determined by how they’re stored; thus, extra care must be taken to avoid their destruction. Depending on the item being stored, you may be required to keep them in airy, fresh, well lit, or dark spaces. All instructions will be provided by manufacturers to make storage easier for you and your household.

Additionally, the shelf life of water testing kits is limited, depending on whether they’ve been opened or not. These test kits or strips need to be stored in cold and dark spaces since they thrive in such environments. As much as possible, keep these strips away from bags of treatment chemicals such as bromine and chlorine. Natural elements such as temperature extremes, direct sunlight, and exposure to volatile treatment products can reduce the shelf life of your treatment kits.

What are the Recommended Levels of Some Common Minerals found in water?

The essential dietary minerals required in water are very relative; thus, they vary from mineral to mineral. Potable drinking water or clean water for other activates needs to have calcium, sodium, Potassium, Zinc, Copper, Iron, and magnesium, among others, to be considered dietary standard for human consumption. Iron is essential because it aids in the transport of oxygen around your body, and also encourages normal body functions. Calcium, fluoride, and other minerals are present in water to assist in the growth and maintenance of healthy bones and teeth, which ultimately keeps you active and more youthful. These minerals are available in their right proportions to allow for better growth of all human organs and their maintenance.

My Test Kit Shows that my water has Zero Chlorine, but I Know It’s There. What could be causing this?

Chlorine is used by many companies and municipal areas to purify water. It is even used in commercial and household pools to keep the water clean for a more extended period. Chlorine, in recent times, has been found to have some adverse effects on the human system, but it still does a fantastic job of keeping your water free from contaminants.

Occasionally, it is advised that you test the levels of chlorine in your water to decipher as and when it will be ideal for increasing the dosage. The test may come out with your chlorine level reaching zero, even though you have some amount within. This is usually caused when the chlorine used is ineffective.

The ineffective nature of the mineral doesn’t allow your test kit reactant to have a vivid reading, thus the zero result. The only solution for this is to make use of a new chlorine brand in your pool. Increase the dosage used and then take another reading, to be sure that the chlorine used is taking effect.

1What Chemicals and Minerals Should I Test Well Water for?

The best place to start all your testing is by undertaking a general mineral analysis. This will include a combination of nitrate and coliform bacteria and may even include other elements such as iron, bacteria, manganese, copper, sulfate, ph, hardness, and many more. You may want to test for other substances such as herbicides, heavy metals, organic compounds, and pesticides, especially if you live near a gas station, highway, agricultural areas, or an industrial area. There are different types of tests, and each one is explained below.

  • General Minerals Test

This kind of test will usually contain metals such as manganese, and iron, along with calcium, chloride, potassium, magnesium, and sodium. General mineral tests are generally used to check for the presence of sediments and stains. These tests tell you what the problem is, and can also help you identify where the odd odor or taste in your water is coming from. An additional criterion for tannin is recommended you’re having problems with color in your pool or any brown staining.

  • Coliform Bacteria

Many might wonder what Coliform Bacteria is. This is a form of bacteria often found in surface water, within the soil, and on vegetation. It can also be found in the feces of warm-blooded animals, in which instance it is referred to as e-coli. E-coli is a bacterium with a long lifespan. It can survive for long periods in your water, and can also be transferred to other places via insects.

  • Lead & Copper

The first draw of water is the best sample to use when testing for lead and copper. Also, the source of this first draw needs to have been stagnant for up to six hours prior to your experiment. There are some instances where the copper and lead levels are increased due to the plumbing system. In such cases, you will have to flush the faucet for a minute or two before collecting your sample.

  • Nitrates

When nitrogen from animal wastes, fertilizers, municipal sewage, septic systems, and decaying plants are combined naturally with oxygenated water, nitrate is formed. The presence or exposure of children below six months to nitrates can cause the blue-baby syndrome, also referred to as methemoglobinemia. This is a severe condition that can lead to somas and death.

  • Pesticides & Herbicides

These substances are used to control both insects and weeds and are used in many farms and homes to curb the spread of pests on farms and around homes. Pesticides and chemicals such as herbicides enter your groundwater when used on farm fields. Drinking water with pesticides may not affect you initially, but with regular consumption, the development of cancer or any other serious health problems is a risk.

Final Verdict

When detecting the level of contaminants in your water, the usage of testing kits is the best way to do it. These kits are considered a very worthy investment for every home and we have established some of their numerous benefits, which include their ability to offer countless operational options, their ability to test and detect multiple types of contaminants, and many more.
