What Could’ve Been Better?

While testing this product, we did not come across any such serious drawbacks. However, we found out that the instructions given on the bottle are wrong, and the ones printed on the pamphlets are accurate. So, we recommend following the instructions printed on the pamphlet only.

Also, it doesn’t test pesticides in the water supply.

Why Did We Like It?

The best part of this testing kit is the fact that you get your results within 30 seconds. Meaning, you don’t need to wait for days for the professional to arrive to check the water quality.

Moreover, the color chart is designed on the bottle, which makes it super easy to measure the range of the water hardness. Meaning, you will not get a pain in the neck while trying to measure the ppm. Also, the chart measures not only in grains per gallon (GPG) but also in parts per million (PPM). 

Moving from red to green, you can easily make out how soft or hard your water is. Furthermore, this kit comes with 50 strips which can last up to a year. Plus, the unused strips have a shelf life of ten months if appropriately kept in an air-tight container, which is a bonus if you ask.

Interestingly, all these handy features are coupled with an affordable price tag, so you get excellent value for money.

What Could’ve Been Better?

This water testing kit is one of the best available on the market, mainly because it is relatively easy to use and produces results within seconds. However, while testing, we realized that it becomes difficult to understand the results because the colors are so similar to each other. Also, we found some extra strips, which were unnecessary, considering the shelf life of the kit. 

Pros
  • Reasonably priced
  • Gives results within seconds
  • Can be used for up to 10 months
  • No calibration required
  • Accurate results
Cons
  • Similar colors make it difficult to understand

Why Did We Like It?

The JNW Direct Pool and Spa Test Strips come loaded with excellent features. However, its USP is that even though it is a swimming pool and spa water testing kit, it is extremely easy to use. You just need to dip the strip into the water and compare the color on the strip with the one on the bottle. 

What is more interesting is that this kit can test for seven parameters. As such, you can use this kit for testing water hardness to test the alkalinity of the water and a lot more.

Apart from this, you can track, monitor, and even record your testing strip results, thanks to the mobile app included with this testing kit. Even we were even surprised to hear this.

Also, this testing kit comes with an e-book which you can download. You get to learn more about the results along with maintaining your pool all year long. Hence, it helps you to maintain accuracy. 

What Could’ve Been Better?

While testing this kit, we did not come across any significant flaws. However, we found out that once unpacked, you are required to use the 100 test strips within 90 days, which is nearly impossible. So, this might be a drawback for homeowners. Also, the chlorine test scale is far too high, i.e., 0 – 1000 ppm.

Pros
  • High-quality strips
  • Convenient to use
  • Delivers results with accuracy
  • Mobile app helps in tracking results
  • Gives results within a minute

What Could’ve Been Better?

This hard water testing kit does its job excellently, but our only gripe is that it cannot test other parameters. It can only be used for testing the hardness of the water. If you want to test different parameters, you will have to buy another kit for testing other parameters.

Pros

  • Reasonably priced
  • Delivers accurate and reliable results

What Could’ve Been Better?

It is, without a doubt, one of the excellent testing kits on our list, mainly due to its reasonable price. However, while testing, we found out that the color chart didn’t indicate what the yellow color represented, leaving us in a maze. Also, the bacteria tests require waiting for 48 hours.

What Could’ve Been Better?

This product works exceptionally well, but we couldn’t help but notice a couple of downsides. First, we noticed that the water hardness chart shows measurement in mg/l and not in GPG. It would have been great if both scales were printed on the chart. Also, it does not tell you the exact hardness of the water.

Pros
  • Instant results
  • Relatively easy to use
  • Ample amount of strips
  • Accurate and reliable
  • Nice packaging
Cons
  • GPG scale not mentioned

Hard Water Test Kit Buyer’s Guide

Buying the best hard water test kit is quite a challenge. Knowing the top 9 hard water test kits available on the market is not simply enough. There are several factors that you need to consider before buying a hard water test kit.

So, to make things easy for you, we have explained all the important factors that you must consider in this section. We hope that after reading this, you will be able to choose the correct hard water test kit for your needs. 

  1. Water Source

The very first thing to keep in mind is the source of water you will be testing. There are kits in the market which are only meant for testing specific sources of water. At the same time, there are others meant for all purposes. 

So, if you want a test kit for testing only drinking water, we recommend you go for a model that is designed for that purpose only. But, if you will be testing water in general, you must go for a test kit meant for all sources.

  1. Procedure for Testing

The next thing to keep in mind when buying a hard water test kit is the type of testing procedure you want. If time isn’t a factor, you may opt for a kit that allows you to send the water samples to a testing center. 

But, if you want to know the results instantly, then we recommend you go for those test kits which deliver instant results.

  1. Impurities

You must keep in mind the substances that are to be tested. Not every kit is capable of testing all kinds of impurities. Some kits can test almost all the substances, whereas others test for only 2-3 impurities. 

If you know which impurities you are going to test, we recommend opting for the latter. It would also be a cost-effective option for you. But, if you aren’t sure what is to be tested, go for the first one.

Verdict

If you are suffering from water-borne disease or skin and hair problems, you must immediately test the water hardness of the water. This will help you to monitor the water quality and also keep yourself safe and healthy.

On this note, we come to the end of our informative, review-based guide. But before signing off, we would like to mention our top picks from the list. Overall, Varify Premium Water Testing Kit is the best because it tests for 17 parameters. And if you are looking for an affordable kit, then the Hach 145300 Total Hardness Test Kit is best.  

Until next time. Adios!
