2023 Buyers Guide to the Best Water Test Kit

Whether your water source arrives at your home by the city or county water department or pumped from a natural well, the domestic water that flows through a home should be clean and healthy to drink, and free of harmful pesticides, iron, and lead. 

According to the Natural Resources Defense Council, over 10 million US homes contain lead pipes. Over time pipes corrode and harmful metals seep into the water. Corrosion is not a flavor, and it’s unhealthy and can sometimes lead to gastrointestinal illnesses.

In addition, from 2017 to the present, on average, 60% of US homeowners searched for information regarding Chlorine water testing kits, 30% searched for a combination of bacteria, lead, VOCs and harmful mineral water test kit options, and another 10% defined their search to hard water testing kits. Clearly, there is a growing need for home water source test kits for homes well water sources and aquariums.

From determining Ph balance to testing water “hardness” – the ratio of dissolved calcium and magnesium – to ensuring the water in swimming pools and aquariums are safe for the kids, and the fish, a water test kit is an essential tool to test against Environmental Protection Agency (EPA) standards. 

Key Considerations When Choosing A Water Test Kit

Not all water testing kits are made the same, from paper test strips to liquid drops, third-party lab testing to a kit containing a miniature in-home battery-operated centrifuge to spin and test the water. The good news is, no matter the type of water testing kit you ultimately decide to purchase, it will yield the same results. Or will it?

Prices for water testing kits range from twenty dollars for a basic test strip kit to hundreds of dollars for a scientifically designed water testing kit plus extra fees to send the water to be tested in a professional lab. Before shelling out your money on a water testing kit, take these factors into consideration:

Your Water Sources

Are you in an urban area or suburban farm country? The former may contain high levels of lead and fluoride, and the latter includes many types of invisible pesticides and bacteria. 

Is your home’s water provided by a municipal water source or a private well in your backyard? Municipal (city) water table information, including the latest water test results, is easy to search for on the internet. Well water is about as close to a mystery as it gets, and most likely, is not treated regularly, if at all. Please educate yourself on your water source related to your geographical location.

Water Flow Speed

Count the number of inlets where water flows into your home. Water moves at different rates depending on its quality. Slower moving water means a greater concentration of chemicals and metals. Pipes bring water to sinks, tubs and showers, toilets, water heaters, dishwashers and washing machines, and ice makers.

Plumbing Material

Determine the material construction of your pipes. Is your home’s plumbing made of PVC or metal? How old are the pipes? Harmful chemicals also can compromise the integrity of the lines, a sure sign those same chemicals are swirling around in your drinking water and slowly causing damage to your appliances. 

Hard Water Testing

Hard water wreaks havoc on everything, and heavy metals can weaken the integrity of clothing and leach permanent rust stains onto the surface of porcelain and tile.

Before you test your water, educate yourself on the hardness of the water in your region by making a call to your water municipality. Then determine if you need a water conditioner (treatment medium crystals) or water softener (reverse osmosis and salt) and the individual operating and installation costs  

Type of Water You Are Testing

Consider how many “types” of water you have to test.  Are you testing only the water in your home? Your home and a pool? What about home, pool, and aquarium. Water is water, but more water sources mean more water testing. And that means more time, patience, education and a kit that can yield the best results. Ask yourself, are you able to devote yourself to being a DIY water tester, or do you want to trust a lab to test your water? Lab testing comes at an extra cost.

Pool and Aquarium Water Testing

Pools and aquariums are sensitive to numerous diseases, fungi, and bacteria and often require regular testing. It’s essential to have enough testing materials on hand. Build the cost into your monthly budget to pivot quickly in the event you need to treat any of your water sources. Your fish and kids will thank you!

Water Contaminant Testing

Determine what specifically you would like to test for.  Is it for something specific?  Or do you need a more comprehensive test to uncover what potential toxins and chemicals may be lingering in your drinking water?  Some water test kits provide only for specific minerals, while others can test for hundreds of water contaminants. If this is your first water test, the more robust test may be the way to go.

Testing Process

The water test kits range from results in 5 minutes to results in 5 days.  Depending on what type of test you use, it may only require placing the test strip in your water to see the results right away.  Other more comprehensive test kits require filling a vial with the water to be testing, sending it to a lab to do the diagnostics, and returning the results to you in approximately 5 days.  Other specific testing kits, like a digital pool test kit, will return data to you instantly.

FAQs For Water Testing Kits

How safe is my water to drink right Now?

Seems like a rudimentary question to be asking yourself. But it is the first and most important question you should be asking yourself before you even start your homework and research on water testing kits. 

Determine how old your home is, what the plumbing is made of, where your water originates from – an underground well or city reservoir – and look online to get an overview of the last 5-10 years of water testing results from your local municipality. 

Knowing how safe your home’s water is before starting the process helps you decide what type of water testing kit to purchase, understand what parameters to test for and more importantly estimate the potential costs should you need to purchase a filtering system, a new water heater, replace plumbing or ultimately have the water tested and treated professionally. 

What do water testing kits test for?

The more comprehensive water test kits will test for over 100 chemicals in your water.  Common tests include: Lead, Arsenic, Heavy Metals, Iron, VOCs, Nitrates, Chlorine, THMs, E. Coli bacteria and more.  The more budget friendly at-home options can sometimes focus on just a few specific toxins to be tested for.  We recommend starting with a comprehensive water test to uncover all possible impurities.  Then you can refine your tests down to more cost effective water tests to spot check and ensure your treatment course of action is working.   

How do water testing kits work?

It depends on the type of kit and what you are testing for.  If you are using a water test kit for your home’s water, there are instant water test kits or kits that you mail in to be analyzed.  For the at-home instant kits, they typically include testing strips that can render results in as little as 15 minutes.  The higher end mail-in kits require you to fill vials of water and ship them to the company’s lab (typically pre-paid shipping) where they analyze the water results.  In both cases, the water test kits will come with detailed instructions to guide you through the process.    

How accurate are water test kits?

Mail-in water test kits can be extremely accurate.  They cost a little more, but you come away with a much more comprehensive set of lab results – which is the purpose of testing home water to begin with. For example, the SimpleWater Tap Score professional water test kit uses EPA lab testing methods to quantify over 100 chemicals in your water.  They then provide treatment support by professional engineers on the best way to resolve any water purity issues. Conversely, instant home water tests are less comprehensive than lab testing, but they do an excellent job for testing specific chemicals and minerals, or for quick spot checks.      

Should I have my water tested first before I buy a water test kit?

Yes and No. If you are able to get a complete water table test from your local municipality or in a tapwater database, you’re probably okay to get started deciding what type of water testing kit you’d like to purchase, and how often you want to test your home’s water, and pool and aquarium too!

If you’ve never had your home’s water tested, inquire about a test from your local municipality or shop online for a service that fits within your budget. If you go this route, ask the technician questions about formulating a treatment plan, and ask to see the results so you can understand what to look for when you start your own DIY water testing.

How often should I test my water?

The suggested water testing schedule is every six months. If you live in a more rural area, test more frequently. If the pool, spa, and aquarium water need to be tested, you’re adding additional days or weeks to your schedule. 

Create a water testing plan so that you’re able to test regularly as well as seasonally. This requires that you have enough test strips or drops, so stock up or purchase a water testing kit with plenty of supplies and get into the habit of testing your water sources at the same intervals so you can get them to the lab and get the results back on a consistent basis. 

Final Thoughts on Finding the Best Water Test Kit

Clean water is an essential community resource. Water test kits support greener living environments, preserve water-powered appliances, help properly hydrate the body, prevent the spread of disease, and provide an overall sense of well-being.
