Pool Water Testing Kit Buying Guide
Now that we know of the best pool water testing kits, it is time we discuss a few things regarding pool water testing kits and pool water hygiene in general.
Is Pool Water Testing a Necessity?
A lot of people assume that their municipal water is safe as there are rigorous tests done at the plant to ascertain water quality.
Well owners, on the other hand, ignore testing their water with the belief that its natural source is not contaminated.
The truth of the matter is that your water source may be contaminated and the contaminants are transferred to your swimming pool.
Why test well water?
In the case of well owners, the Penn State report is conclusive as to why well water should be tested. In the report, over half of the private wells failed at least one water standard test. But how exactly is well water contaminated?
There are so many ways through which well water gets contaminated. If you have livestock around the well, you should be wary about contamination. Another cause for contamination is proximity to a septic tank, factory, mines, oil rigs, and landfills.
Also, if you use pesticides around the well, or there is a gas leak nearby, there is a high risk of contamination.
Why test municipal water?
There are so many tests performed at the municipal water plant in accordance with the laws and regulations.
However, we have witnessed several cases of municipal water contamination, either at the source or in the main supply’s plumbing systems.back to menu ↑
Pool Water Contaminants and Legal Limits
Now, which are some of the common elements when it comes to water contamination?
When Should You Test Your Pool Water?
A lot of people have been asking, when should you test your water?
Yes, there are some common signs of contaminated water, but in the first place, it is important to have a regular water testing schedule. So, don’t wait until your pool water starts showing signs of contamination – buy a pool water testing kit today.
Now, back to the main objective of this segment: when should you test your pool water, and what are some of the signals that your water may be contaminated? And most importantly, which test should you perform? That’s what we want to discuss.
- Recreational Water Illnesses (RWIs) – If you and your family experience recurrent bouts of stomach problems, that is a classic sign of pool water contamination. Honestly, you can’t guarantee that your kids will finish a swimming session without gulping some pool water. I. this case, focus your test on coliform bacteria which is synonymous with most gastrointestinal illnesses.
- Skin irritations and disorders. The biggest culprit here is pH which leaves your skin dry and itchy. Test your pool water regularly and ensure the pH is balanced. Besides pH, elements like arsenic and barium may lead to skin irritation, cause lesions, and worse, skin cancer. For that reason, you should emphasize on testing your water comprehensively.
- Lead and corrosion in plumbing – In almost all the water contamination cases, Lead was the notorious element. If you aren’t sure whether your plumbing has lead pipes or it shows signs of corrosion, do a pH, copper, and lead test. Most of the old pools were painted with lead-based paints, and this often leaves lead dust settles at the bottom of the pool. If you’ve had fireworks around, also consider a lead test as the remnants of the fireworks which have Lead might find their way to your pool.
- Agriculture – Whether you have a garden for intensive farming or you keep livestock nearby, chances are high, your well water may be contaminated. In this case, test for pesticides, nitrates, and coliform bacteria.
- Saltiness – If your pool water turns salty, your water is contaminated. Your tests should target sodium, Chlorine, and TDS.
- Scaly residue – If your pool water leaves some scaly residues, consider a water hardness test.
Types of Pool Water Testing Kits
Before you venture out to the market, here are three types of pool water testing kits available and how to use them.
1. Test Strips
These are the most popular testing kits. They are affordable and, but unfortunately, they don’t guarantee 100% accuracy. But that is not to say there aren’t any good test strip water testing kits. Some models are known for high accuracy and efficiency. Strips are best if you want a kit for initial screening or testing for water hardness and maybe pH.
Strips are made from specific materials which, when chemically treated, they react and exhibit a specific color change, thus confirming the absence or presence of certain contaminants. The color change is matched on a color chart to determine the exact contaminant. This method is very subjective just on the fact that the youth and men are not so good at colors.
2. Digital Testers
These are quite complex, and unlike test strips, they probe the water properties that change with the presence and amounts of different contaminants. Digital Testers display the quantities in digits eliminating errors.
But unfortunately, digital testers are not accurate in all tests. Furthermore, TDS (total dissolved solids) tests are not conclusive as they don’t test microbial and lead, which are common pool water contaminants.
3. Lab Test Kits
Experts agree that lab tests are the best if you want to know even the smallest amounts of contaminants in your pool water. Lab test kits have vials where you fill the sample and send it to professional labs. While these tests are accurate, the results are not immediate.

Factors to Consider when Buying Pool Water Testing Kits
There are several important considerations to take into account before adding any pool water testing kit to your cart.
There are so many brands in the market. Always stick to the household names. Avoid the cheap, little known brands. Some of the best pool water testing kit brands to watch out for include: Pentair, PoolMaster, La Motte, and Taylor, just to mention a few.
2. Water source
There are different types of water testing kits. Some are designed to accurately test municipal water while others are strictly for well water. For examples, the Watersafe WS425W is designed for testing only well water so it may not be resourceful in testing municipal water. So, buy your pool water testing kit depending on the source of your pool water.
If you have a well, the common contaminants you are testing for include bacteria, Lead, fluoride iron, manganese, arsenic, nitrite, nitrate, and radiological. You won’t need chlorine tests unless you have disinfected it recently.
For those who rely on municipal water, the standard tests you require are for Chlorine, Lead, and maybe fluoride. There is no urgency of testing bacteria unless there is a scare like recurrent gastrointestinal complications.
3. Self- test vs. lab-test
This is pretty straightforward. If you want to self-test, go for a home pool water testing kit. As for those who would like to seek professional help, There are also lab pool testing kits.
4. What tests?
It is hard to come by a single pool water testing kit that tests the over 100 water contaminants and bacteria. But this is something lab tests can manage.
When choosing a pool water testing kit, make sure you pick the type that is designed to test the probable contaminants in your pool water. There are those which test for heavy metals only while others may be only for water hardness or pH, among other common pool chemicals.
While brands may promise accurate and reliable results, only independent tests can confirm this. Check out for water testing kits approved by EPA and other trusted independent certifications.
