Check The Quality Of The Water With A Test Kit for Your Home

For many years now, we have all known that tap water has a certain degree of contaminants that gardening experts don’t even recommend for our plants, let alone for ourselves.

That said, a water test kit is a right thing to buy if you want more information on the everyday water you’re using, so let’s learn more about what these babies can do.

Benefits of a Water Test Kit

Sure, the obvious reason for purchasing a water testing kit is to detect various water contaminants but there are actually a lot more hidden perks to making this purchase:

  • First of all, you won’t need to have any professional service to determine the water contamination levels because you can do that by yourself with this type of kit. Not only that, but you can also find out the exact contaminants that are in the water. It’s true that lab testing is different compared to home kits but they are still something that can provide you with valuable information.
  • You won’t have to wait for lab results to come in anymore. If you decide to turn to experts for testing, you will be required to wait for the lab analysis to return, which can take a while. Plus, in these dire times, you want to avoid any unwanted people crossing your doorstep, and professional water testing sometimes requires an expert coming over to pick up the samples.
  • It’s not a complicated process to do by yourself. You simply have to follow the manufacturer’s instructions, which mostly imply collecting water into containers. The steps for using the kit as well as the result interpretations are provided with the purchase of your kit.
  • Such a test can also help you determine if you have any filtration devices that are simply not doing their job. Furthermore, this can help you decide if you want to get new systems, like maybe a disinfectant shower hear or a new under-the-sink filtration unit. Whatever the case, a water testing kit will give you the information needed to decide what are the right measures to take to benefit from a cleaner and safer water.

How to Choose a Water Test Kit

Whenever you purchase a product for the first time, it’s natural to have a lot of questions regarding the best set of features that can make or break the deal. When it comes to a water test kit, there are three important factors to keep in mind as a shopper:

  • The water source – It’s not uncommon to come across water test kits that are catered to the specific collection source. For instance, some of them are better for pool water, while others are more suitable for tap water. That’s because the water you drink is usually tested for a different variety of contaminants compared to the water you sometimes just swim in. So, it is only natural to buy a water testing kit that addresses the potential list of contaminants found in that water source.
  • The testing procedure – There are mainly two types of water test kits that money can buy: the ones that you have to see through yourself from start to finish and the ones that require a sample collection which is then sent to a lab for a more comprehensive set of analysis. Naturally, there are pros and cons to each of the two. People who typically choose a water test kit they can do themselves at home are those that are too eager to wait for the results or simply want to know about the potential presence of some common water contaminants. Lab testing, on the other hand, takes longer, but it often delivers an in-detail report of your current water status.
  • The contaminants – Last, but not least, you should know that not every water test kit available on the market can detect the same type of contaminants as all the others. Most of the good kits should be able to test for common contaminants, which include copper, lead, chlorine, and iron. The less expensive kits will usually test for one or two contaminants, which is why most people choose more complex kits so they can get more contaminant-related information.

How to Test Your Water

Hard water is pain to have to deal with. If you want to know how to test water softness, here are a few methods that might help you:

  • Your city might provide you with this information without you having to do anything. Your water supplier will be able to give you intel on the source of your water, as well as what it contains, so it’s likely to include the water hardness as well. Alternatively, calling your local water municipality might also provide you with this information.
  • A water hardness test kit might also be able to help you. These kits usually cost less than $15 and they come with test strips and a color chart so that you can identify your water hardness. Once you receive your water hardness testing kit, you fill a glass with cold water, place the test strip inside it, and remove it after a few seconds (the instructions delivered with your water hardness testing kit will tell you just how long you have to wait). You will notice that the strip chances color, and then you can compare it with the included color chart.
  • If you don’t want to purchase a water hardness testing kit, there is another and less accurate method to test water hardness. Grab a clean and clear empty bottle, fill it about 30 percent with water from the tap, add a few drops of whatever pure liquid soap you might have in your home, close the bottle and shake it. If the water is hard, you will notice the water is cloudy/milky and there aren’t any fluffy bubbles. 

Water Hardness Scale

Hard water can be a rather complicated topic because of the technical details that you have to know if you want to understand more about what soft and hard water actually means. For instance, water hardness is measured in gpgs, which is short for “grain per gallon”. 

Some water testing methods will give you a number and, based on that number, you can identify the water hardness in your home:

  • If the number is between 0 and 3, that means that you don’t need water softening.
  • Numbers between 3 and 7 indicate the water is moderately hard and it can leave you with dry skin and spotted dishes.
  • Numbers between 7 and 11 show you that your water is mineral-packed, leading to problems such as crusty faucets and pipes.
  • When your water is between 11 and 15, that means that it’s very hard.
  • Any number above 15 tells you that you’re about to deal with all major problems caused by hard water: very dry skin, iron stain, soap scump, spotty dishes, etc. 

A water softener can go a long way in helping you solve this problem. Here are a few water softener facts that might help you:

  • A water softener usually regenerates every 5 to 10 days.
  • Some water softeners will only regenerate when needed, so a 40-pound bag added every 6 to 8 weeks to your softener should do the trick.
  • A highly-efficient water softener shouldn’t cost you more than $4 each year.
