Let’s do a deep dive to know whether water softeners will benefit your home!

Seven Advantages of Water Softeners 

Advantages of Water Softeners

Prevents Scaling Inside Pipes and Fixtures 

Hard water contains minerals like magnesium, calcium, iron, and manganese. The precipitation and build-up of these minerals in the water pipelines and fixtures cause scaling, like an extra coating on the surface. It may restrict the flow of water and blockage around fixtures. You may even notice leaks as some junctions build up in clogged areas.  Water softeners solve this issue by preventing scaling in fixtures and pipes.

Improves Lifespan Of Your Water Appliances 

When I started using water softeners, I soon realized the difference they made to working water appliances. It took less time for my water heater to heat water. My water filter indicated the need for filter replacement after an extended period. The shower didn’t clog anymore. The utensils came out all clean and shining from my dishwasher. All thanks to the soft water supply from the water softening unit.  

Improves The Taste Of Drinking Water

Improves The Taste Of Drinking Water

While reaction to water taste might vary from person to person due to personal preference, you will find the soft water tastes more pleasant. Even though hard water tastes slightly bitter and smells like chlorine, it is not detrimental to our health. 

If you are used to drinking water rich in hard minerals, you will find the taste of soft water unpleasant. But, once you are used to the taste of soft water, there’s no going back.  

Makes Water Healthy For Your Hair and Skin 

Using water softener units in homes will show visible improvement in your dry hair and skin quality. Hair looks more shiny and manageable, with less hair fall. 

Skin irritation and dry skin are common skin problems associated with unsoftened water. Soft water has a slippery texture, giving your skin a smooth and healthy glow.  

Keeps Dishes and Glassware Clean 

Are you worried about the embarrassment you face when your guests point out water spots on your utensils? You should know that these water stains appear when hard water evaporates from the surface and leaves behind insoluble mineral precipitates on your silverware. 

Well, worry no more. Water softeners supply soft water which does not leave stubborn reddish-brown stains on your dishes and glassware.

Prevents Detergent Curds In Washing Machines 

I have been a chemistry student, so let me explain the working of soaps and detergents with hard water. When we use soaps and detergents with hard water and try to form leather, a white slimy substance called scum or detergent curd is formed.  

Scum results from the reaction of hard water minerals like calcium and magnesium ions with soaps and precipitation of their salts. The effectiveness of soap is reduced, and the resulting scum sticks to the clothes and even clogs the drain holes at the bottom of washing machines.  

To overcome this problem, make sure you use a water softener for soft water supply for washing clothes.

Reduced Costs and Water Usage

Let me draw you a mental picture here.  

Less mineral levels in water mean less build-up and scaling in pipelines and appliances. Less build-up and scaling means constant water flow rates in pipelines without blockage and increased efficiency of water appliances. Increased efficiency means lesser energy consumption, reduced costs, and more output. See how water softeners can do wonders for your household in the long run?  

  • The water softener installation might seem expensive initially; still, it sure does help you save a lot of money on maintaining your household water connections and appliances in the future.

Five Disadvantages of Water Softeners 

Disadvantages of Water Softeners

Negative Effects On The Environment Because of Sodium Addition

The environment is a delicate balance. According to researchers and water experts, drainage from water softeners has high salt content. These high levels of sodium chlorides, when discharged into your septic systems or open fields, become a hazard for plants and trees.  

When this salt-rich soft water enters the soil, it changes its texture, pH, and percolation properties. Also, the concentrated salty water has very high osmotic potential and competes for water with the roots of plants and trees, affecting their growth and development.

May Damage Your Pipes 

On the one hand, soft water prevents scaling and build-up in pipes and appliances, but on the other hand, it causes corrosion. Water with a lower mineral concentration becomes an excellent solvent for the dissolution of metal ions. The copper and lead ions from pipelines dissolve into the soft water, thus causing the degradation of pipes.  

Scaling provides a harmless coating on the pipe surface, preventing corrosion. Thus, to overcome this problem, running hard water in your entire plumbing for one or two weeks is advised to allow limescale build-up, which is non-reactive and insoluble. Thus, using soft water after this deposition will no longer cause corrosion of your pipelines.

Wastes Water During Regeneration 

Wastes Water During Regeneration

The regeneration process is a cleaning cycle run by various salt-based softeners. The resin beads inside the water softening mineral tank are covered with mineral ions after treatment with hard water, which needs to be washed off from time to time.  

Thus, a good amount of clean water is pumped in at high speed for the regeneration cycle, which is then drained and, thus, wasted. Keep in mind that installing a water softener might increase your water bills.

Removes Essential Minerals Like Calcium And Magnesium from Water

As I said earlier, hard water is not a health hazard. In fact, it is pretty beneficial on daily intake. All the minerals like Calcium, Magnesium, and Iron present in hard water are essential for your body and its development. Removing these healthy minerals from the water might lead to their deficiency in your body.   

Not to be at any loss, keep a separate cold water pipeline to supply hard water, without passing it through water treatment systems, for drinking and cooking purposes. So, why take dietary supplements when we have a direct supply of hard water in our homes?

Expensive to Install + Difficult for a Beginner + Added Maintenance Costs 

The one-time installation cost of high-quality water softeners is relatively high, followed by maintenance costs throughout its lifespan.  

Although the water softeners come with a DIY installation guide, it is not likely that you will be able to install them independently if you are not a handyman. A trained or experienced person usually install the unit correctly without leakage. Plumbers also charge pretty high fees on an hourly basis.  

Even though the main maintenance requirements only account for monthly salt replacement, which is barely $3 -$4 per pack, you cannot ignore it. Choosing the right, well-designed water softener system that fulfills all your needs and fits your budget is quite stressful.  

So, take your time, analyze tap water quality and make a cost-effective decision.  

Here’s The 1-Line Takeaway: 

Water softeners are more of a necessity than a luxury because most families have no choice but to install a water softening unit to overcome hard water woes, as the disadvantages of hard water outweigh its advantages. 

Why Are Salt Based Water Softeners Banned?

Which States In The U.S. Have Banned Salt Water Softeners and Why

Keeping in mind the effect of water softeners on the environment, various states and cities have passed laws and guidelines regarding their use.   

Such strict policies can be seen in California, Arizona, Texas, Massachusetts, Connecticut, Michigan, and a few small cities in the United States.

Now, why such strict actions against the wonderful water softeners? Well, the answer is straightforward – adverse effects on Mother Earth.  

The issue is against the use of self-regenerating salt-based water softening systems that discharge concentrated salty water into the city’s sewage system. They use the ion-exchange process to trade sodium ions for hard mineral ions in the resin bed during the softening process.

When mixed with groundwater or discharged into the field, this water enters the soil and disturbs the growth of our beloved plants and trees.

Is Softened Water Worth It?

Health Precautions You Should Take Before Consuming Softened Water

So far, you have learned about the various pros and cons of water softeners, soft water, and hard water.   

Softened water might seem to have various advantages over hard water. The trouble free-working, no build-up and scale deposits, increased life of water gadgets, healthy hair, glowing skin, and the list goes on. 

But, one major disadvantage of using salt-based water softeners is high sodium levels in the water. Although sodium is an essential component of our body and helps generate nerve impulses and maintain the osmotic balance of the body, excess of anything is dangerous. 

It increases blood pressure and causes cardiovascular diseases and kidney problems in the long run. Patients suffering from hypertension, heart and kidney disorder are strictly kept on a low sodium diet. 

To overcome this problem, you can use potassium chloride pellets instead of sodium salt in your water softener. It does the same function and gives an additional benefit to your health.  

You can also look for other water softening alternatives that do not use salt or keep a separate tap for drinking and preparing food.  

Another thing to remember is the dissolution of heavy metal ions like Copper and Lead into the softened water. If present in toxic concentrations, these metals may prove injurious to our health.   

As discussed earlier, you can allow hard water to run through your household water lines for a few weeks, after which you can switch back to soft water. The inert layer deposited on the inner surface will ensure no corrosion.  

  • All recent households have PVC and acrylonitrile pipelines, which are considered best for carrying water without interactions.

Water Softener Pros And Cons FAQs

Which States In The U.S. Have Very High Water Hardness Levels? 

Indiana, Texas, and Minnesota are among the US states with the highest water hardness level.

Why Is My Water Still Rusty With A Water Softener? 

Ans: There can be 4 reasons for that: 

  • High Iron Levels: Different grades of water softeners remove different levels of minerals. Maybe your water softener is not designed to remove Iron from the hard water. You can install an iron filter along with your water softening unit. 
  • Clogging in your Resin tank: Ensure your brine tank has not run out of salt. Timely input of salt pellets is necessary for proper functioning and cleaning your water softener. Check your water softening unit for clogs and leakage to ensure proper working. 
  • Corrosion of pipelines: Soft water can also sometimes dissolve metal ions like Iron, Copper, and Lead from water pipelines. To overcome this problem, run hard water through your pipelines for a week to form a mineral layer on their surface which will later prevent direct contact of soft water with the pipe surface.
  • Check the Bypass valve: If your water softening unit comes with a bypass valve that allows you to have a constant water supply even when a power outage or your water softening system shuts down. If the bypass valve is not in the correct position, hard water may be mixed with soft water.

What Are Different Types Of Water Softeners? 

There are mainly 3 types of water softeners based on their mechanism of action:

  • Salt-based Ion-exchange Water Softeners: These are the typical water softeners we have discussed in this article. The unit comprises two tanks, one resin tank, and the second brine tank. The brine solution is made by adding sodium chloride (salt pallets) into the system, releasing positively charged Sodium ions.

    The positive charge on sodium ions is weakly attracted to the negative charge on resin beads but gets exchanged when strongly attracted hard water mineral ions enter the resin tank. Thus, hard water minerals are left behind, and sodium-rich softer water is supplied to the household.
  • Salt-free Water Softeners – These are more commonly known as water conditioners. These salt-free systems do not remove hard minerals but rather promote crystallization of the minerals like magnesium and calcium carbonate, rendering them ineffective in forming scale or build-up in the pipes and fixtures.

    They use TAC technology to form neutral crystals of hard water minerals in water that will no longer be deposited on the surfaces. Thus, you get all the benefits of soft water without compromising the mineral-rich healthy drinking water.
  • Liquid Water Softeners: These are the latest water softeners used to remove the hardness of the water. They reduce the concentration of mineral ions in the water and thus prevent limescale build-up and precipitation.

    Harmless chemicals like Calgon and Borax are some common liquid water softeners added to the incoming water pipeline, preventing problems arising from high levels of water hardness. As you can see, besides salt-based water softeners, all other systems work without salt. So, they are also a good option for people on a low-sodium diet.

What Are The Different Water Softener Alternatives To Use?

This the water softener alternative that you can use in your households: 

  • Electromagnetic Water Softeners or Descalers: These water softeners fit around the main cold water pipeline and release electromagnetic impulses. These impulses break the insoluble grains of these mineral salts into soluble ions that remain dissolved and prevent scaling or mineral deposits on pipelines. Hence, just like salt-free water softeners, you get trouble-free water that retains its healthy benefits. 

What Is The Installation Cost Of A Water Softener? 

Usually, the installation of a good water softener ranges between $300 to $1500, but it ultimately depends on your type of water softener.

You also get the same water softener with different filtering capacities at different prices. Source water analysis and daily water consumption are important aspects to discuss before buying. Usually, 600 gallons of water per day is sufficient for a family of six members. 

The traditional salt-based water softener is pretty expensive compared to salt-free systems or descalers. The RO systems can again have a high installation cost. 

Do not forget that along with the initial cost, you would have to bear the depreciation and routine maintenance costs of such systems throughout their lifetime.
