Why do you need a Water Softener?

The main purpose of using a water softener is to remove the hard minerals from the water such as Calcium, Magnesium, Iron, Chromium, Nickel, along with many other impurities and sediments to make water soft. Especially in the city area, the water supply generally contains hard minerals, so it becomes necessary to soften the water before you use it.  

But the real question is “Why is hard water so bad?” 

Here are some reasons!

Consuming hard water can lead to many health issues in the long run. Other problems associated with the use of hard water are: 

  • It leaves pale stains on your dishes and faucets
  • It makes your skin dry and itchy due to its corrosive nature
  • It deteriorates water-infrastructure of your household
  • It causes rusting of water pipes
  • It leaves spots on your clothes

Now that we have acquainted you with the problems of hard water, we will talk about the benefits of a water softener.

Benefits of Water Softening System

  • Your skin and hair will be healthy as the soft water treats your skin gently.
  • Appliances that use water will function optimally
  • Efficient energy use
  • Minimal water wastage

How Does a Water Softener System Work?

Water softeners undergo a process known as Ion Exchange, which extracts the minerals such as Calcium and Magnesium from the water to make it soft.

There are resin beads in the mineral tank which acts as anions (having a negative charge). As the Calcium and Magnesium are cations (having a positive charge), they are attracted to the resin beads and attach to them. The resin beads grab the mineral ions and remove them from the water. This process makes the water soft. 

Water softeners nowadays are very advanced and contain many other additional features such as activated carbon, mesh lines, vitamin C balls, and many others. They make your water not only soft but also free from sediments and microbes with added benefits of revitalizing particles. 

How to Pick The Right Water Softener for Your Household?

This section includes tips on how you can choose a water softener. The sixth tip is the most important one. 

1. Figure out Your Needs

First of all, you must figure out two things before considering any water softener:

  • The hardness of water supplied in your house  
  • The maximum amount of water use in your house daily

Determining these two factors will help you make an outline of your household water needs. Knowing the needs will further assist you in narrowing down the options that will best serve you. So when you go to the market, you can evaluate the water softeners more effectively. 

2.  Budget

Water softeners come in varying price ranges, starting from a couple of hundred dollars to more than 4 thousand bucks. You must first figure out your household needs, set your budget, and then look for the water softener that fits that budget. 

3. Capacity 

The capacity of a water softener refers to how many grains of water hardness can the system remove before regenerating water. The capacity may range from 8,000 up to 80,000 grains. Keep in mind that the more the capacity of a softener, the better it will perform in softening the hard water. 

4. Flow Rate

Flow rate means the amount of water that the softener can supply per minute. In other words, it is gallons per minute. We have included the water softener models with flow rates ranging from 7.4 GPM to 22 GPM. These rates should be enough for small household use. 

To make it simple, buy a water softener that can supply 2 gallons per minute flow rate per individual of the household. Example: 8 GPM for a family of 4, 10 GPM for a family of 5, and so on. 

5. Metered Vs. Time-Based Water Regeneration

Most of the water softeners nowadays are equipped with metered regeneration technology. This technology allows the sensors in the system to detect the daily water use of the household and regenerate accordingly. So if the water use increases, the regeneration speeds up and vice versa. Whereas, the time-based regeneration means that the regeneration starts based on time regardless of the water consumption. 

So if you ask us, Metered Regeneration technology is very practical as compared to time-based regeneration. 

6. Certification

Finally, make sure that the product you choose is NSF/ANSI or WQA certified. These certifications mean that it is a quality product based on built and performance. Further, they also guarantee the following points: 

  • Material safety
  • Accuracy in the brine system
  • Standard pressure drop 
  • Standard water softening
  • Wholesome structure

Frequently Asked Questions

Water softener starts developing resins coated with hardening particles over time. The machine undergoes a regeneration cycle where the salt in the brine tank mixes with the incoming water to remove the resins. When the cycle completes, the system starts softening the water again.

An American multinational company, General Electric (GE), manufactures all the GE products.

Pentair Residential Filtration LLC. produces Fleck water softeners.

Fleck and GE are quality water softener manufacturers and are NSF/ANSI certified brands. Without any doubt, their water softeners will last for many years. And to add to it, they have provided a heavy warranty of 10 years on their products.

No, it is not a good idea. Connecting the water softener to the water heating system can cause the water softener to malfunction or even destroy the system.

It is quite complicated to say whether drinking soft water is safe or not. However, research shows that it can be problematic in the long run. You can use a combination of water softener and drinking water plants for making your water drinkable.

Conclusion

Water softeners have great benefits for your daily use but are among the most underrated housing systems. You never realize what you’ve been missing out until you get one. The health benefits of getting rid of hard water are worth your attention.

This guide intends to help you make a wise decision in choosing the best twin tank water softener for your household. We hope we have provided you with all the information you were looking for regarding twin tank water softeners.
