Why Do You Need a Water Softener or Water Descaler?

A water softener is a type of water treatment system that is needed for many households across the world.

Because of one simple reason – the water quality is bad.

The bad quality of water mostly refers to hardness in this article, and water softeners are the most effective way to reduce the hardness and soften the hard water.

People need good-quality water to improve their lives and live happily, and this is where water softeners came into the picture – to improve your life through softened water.

The scale build-up caused by hard water can negatively impact your home’s water pressure, showerheads, faucets, bathtubs, electrical appliances, your skin and hair, and more.

Note: A water softener is not a whole house water filter, you still need to get a proper water filtration system to remove the harmful contaminants from the water.


Cost-Effective Method


I thought a water softener is expensive?

If you compared the water softener cost to the replacement cost of appliances (damaged by scales) and limescale removal cleaning services, it’s not expensive at all.

Getting a water softener is a more cost-effective solution, and you can save even more with Amazon.


Protect Household Electrical Appliances

A water softener can increase the lifespan of water-using appliances like water boilers, water heaters, dishwashers, washing machines, and coffee machines.

The scale form inside the electrical appliances will reduce their performance and eventually stop functioning.

Preventing scale build-up is the only way to optimize your home’s performance.

Top 10 Best Water Softeners for Well Water (Salt & Salt-Free)

  • Read more
Expert’s Commentary:

This APEC FUTURA-15 Water System is one of the best water softener systems with its unique advantages over the rest water softening system.

Unlike traditional salt-based water softener which removes hardness minerals (calcium and magnesium) from water, the APEC FUTURA uses advanced ceramic media to break and neutralize these minerals into a scale resistant crystalline form. It’s a completely natural and safe water conditioning process.

Prevent Scale Buildup Without the Use of Salts or Chemicals 

The converted crystals are neutral, harmless, stable, and heat resistant. And most importantly, they will not stick to your expensive appliances, pipes, and bathroom floor to form lime scales, therefore extending the lifespan of your appliances like water heaters, washing machines, and dishwashers without the use of salt or harsh chemicals.

Additionally, you’ll get softened water which will benefit your skin, hair, appliances, and clothes.

The water softening system is 100% safe for humans, pets, and plants as it does not discharge any salt waste or chemicals into the water. 

It’s salt-free and chemical-free, which makes it one of the best water softeners for home use.

Salt-based water softener vs salt-free water softener image

Maintenance Free

Another thing I like about this system is the fact that it doesn’t require maintenance, electricity, and drainage for wastewater, which is sweet! 

Get this and say goodbye to troublesome salt replacement forever.


It’s cost-efficient as you can use the system for decades without maintenance after the one-time investment.

The system comes with all the parts and accessories for install and is covered by 10 years of limited warranty and lifetime support.

When combined with the best whole house water filtration system, you’ll have the best filtration solution in the industry.

Please note that the system is only suitable for water hardness levels below 25 grains/gallon, so if your water hardness level is beyond that, I’m afraid you’ll have to go for salt-based water softeners. But 25 grains/gallon is considered very hard water, so rarely your water hardness level will pass beyond that.

Easy to Install

The APEC FUTURA water softener is easy to install too, just connecting it to the main water supply line with basic plumbing tools will do, no need to hire a plumber.


  • Salt-free and chemical-free water conditioning
  • Maintenance-free
  • Easy to install

Also, private-owned water softeners are banned in some areas due to the high amount of salt/sodium flushing to the drain lines, so if you are staying in those areas, a water descaler is your ideal alternative to treat hard water.

How to install Electronic Descaler image

The impulse bands produce a strong electric field that alters the mineral crystals in the water to a form that will not attach to appliances and floor.

That said, you will still find the deposits on your bathroom floor, but rest assured that they can be wiped off easily.

Alternative to Water Softener

The Yarna electronic water descaler will not remove the calcium and magnesium minerals in water but simply convert them into ion form that will not cause any limescale deposits, which is basically the main disadvantage of hard water.

Also, the electronic descaling will not waste any water or use any chemicals or salts in the water treatment process, making it a great alternative to the water softener.

Energy Efficiency

The Yarna electronic water descaler uses a thin insulated copper impulse band that’s wide and flat to increase the contact area with the pipe to deliver electrical energy efficiently and create a strong electric field.

This allows the system to treat water flowing at a rate of up to 15.4 GPM with 99% efficiency.


  • High water descaling efficiency up to 99%
  • Support a high water flow rate up to 15.4 GPM
  • The salt-free and chemical-free solution

Why Is Hard Water Bad for You?

Water, whether they are municipally treated water or well water, contains a certain amount of dissolved minerals such as calcium, magnesium, potassium, manganese, and iron.

Huh? I thought these are healthy essential minerals? That’s what I read from nutrition articles.

Yes. They are beneficial when you take in the recommended amount (I’m not posting any controversial findings of them, this is not a nutritional article).

The problem is, these minerals, mostly calcium, magnesium, and manganese will form white color limescale inside the pipes, expensive electrical appliances, and on the floor surfaces.

limescale effects on pipes and appliances image

The limescale problem affects countless households and burns loads of money on cleaning services, appliance replacements, dropped energy efficiency, and pipe flushing every single day.

The hard water will also negatively affect people’s skin and hair.

These are the main issues that can be found in most consumer reports on water softeners.


Hard Water Effect on Pipes

The scales will accumulate inside the pipes and make the pipe interior smaller and smaller, and the same will happen to your water pressure.

Eventually, you’ll be annoyed and irritated by the poor water pressure and have no choice but to hire people to flush the entire plumbing system

$$$$ – See this?

Besides, hard water also contains iron – the main culprit for rust and pipe corrosion.


Hard Water Effect on Water Fixture

Faucet aerators and showerheads are the common victims of scales.

The hard water flowing through these water fixtures on a daily basis causes the scales to form inside in a short period of time.

The scale form inside the faucet aerators and showerheads will reduce the water flow rate by blocking more and more pores, and eventually make them unusable.

It’s also easy for you to find the trace of soap scum here and there on your sink and dishes.


Hard Water Effect on Floor Surface

Do you like the white-color scales that are attached firmly on your bathroom floors?

I bet the answer is no, right?

Most people love beautiful things, and those cloudy thin-film build-ups are plain ugly.

Most people are lazy, and those scales are hard to clean!

So to make your bathrooms look good again, you’re either forced to spend hours and wipe off these stubborn scales with harsh chemicals or vinegar mixed solutions yourself or hire a professional cleaning service ($$$) to do the job.

Neither is a good solution.

Worst part?

You will have to do it again after weeks or a few months, then again, and again, it will never stop until you make a decision to get a water softener or a water descaler.


Hard Water Effect on Laundry

Hard water will cause the washed clothes to feel stiff and rough, sometimes, you can also spot white residue on them.

Not good.


Hard Water Effect on Electrical Appliances

Hardness minerals (calcium and magnesium) in water will form a scale inside the water-using electrical appliances like water heaters, coffee machines, dishwashers, washing machines, water dispensers, and water coolers.

First, the scales will reduce the energy efficiency and water pressure of the appliances.

Talking about energy efficiency, especially for heating and cooling elements, the scale will lower down the effective contact area for energy transfer, hence reducing the energy efficiency and causing the appliance to take much longer time to deliver what it’s supposed to, like heating and cooling.

For instance, a water heater without scale will take 5 minutes to heat the water up to 100 degrees, whereas with scale, the water heater needs 15 minutes to reach the same water temperature, which utilizes 3x the electricity energy!

Because of the lowered energy efficiency, you’ll notice your electricity bill getting increased.

For water pressure, because the interior of the affected electrical appliances gets smaller, which directly reduces the volume of water that flows through the appliances.

The reduced water pressure and flow rate will surely impact the user experience, such as less enjoyment showering, impatient water filling, longer wait time for cloth and dishwashing, and more.

Secondly, the limescale will shorten the lifespan of electrical appliances by damaging the inside components and make them malfunction much earlier than you expect.

Few years down the road, the money wasted on replacing the appliances ALONE is more likely to exceed what it cost to use and maintain a water softener system.

Adding in the extra electricity bill, cleaning expenses, bad usage experience, skincare products, and more, you might as well get a water softener and make all these hassles a thing of the past!

In short, limescale = bad & costly experience for all households.


Hard Water Impact on User Experience

Ok, let’s say you have plenty of money to dump in replacing expensive appliances, professional cleaning services, and electricity bills.

How about your family members’ water-using experiences?

How about the dry skin and hair that annoyed you and your family?

The bad experience caused by limescale is beyond money.


Low Water Pressure Experience

If you ever use pathetic water pressure for showering and washing dishes, you will know how painful it is.

I would rather pay to enjoy a pleasure showering session with high water pressure than a free showering session with miserable water pressure.


Hard Water Effect on Skin

The hard minerals make it tough to wash away the soap from your skin, which can leave a build-up of soap residue that clogs your skin pores and lead to acne or eczema when your body releases its natural oils but is trapped.

The hard water will also make your skin feel dry or irritated as it takes away the natural moisture from your skin.


Hard Water Effect on Hair

After showerings, the dissolved minerals will build a thin film on the hair surface that blocks the moisture from entering the hair which erodes the hair elasticity and causes dry, tangly, dull, rough, and discolored hair.

The hard water will also cause color-treated hair to fade faster as the dissolved minerals can interfere with color.

Besides, the hardness minerals will reduce soap & shampoo lathering and make them less effective in use.

In short, the hard minerals build-up can cause serious deterioration of the whole water-related infrastructure, fixtures, and electrical appliances.

They are unwelcome guests.


Water Softener Benefits

Water is crucial to human beings, and the quality of water you use on a daily basis will directly affect your overall body health and living experiences.

As we discussed earlier, hard water carries a lot of negative impacts, and soft water does the opposite, bringing in plenty of benefits to your life!

benefits of water softeners to your life and home image

A water softener will save you a lot of money and hassle in the long term.

Here are the advantages of using a water softener.


Better Minerals Content

Unlike hard water which contains a high concentration of certain minerals like calcium, magnesium, and iron, the softened water has better minerals content that will not harm your body like what hard water does.


Softened Water is Tender to Your Skin

Human skin needs to be moisturized to stay healthy and soft, and that’s what soft water does, it will not strip away the water off your skin like hard water but let your skin to retain them, resulting in a vibrant and healthy skin.

Want a tender skin without wrinkles? 

Use soft water.


Softened Water is Gentle to Your Hair

Soft water improves the shampoo efficiency to clean your hair more effectively, giving you vibrant and healthy hair after the showering session.


Softer Clothes

Soft water improves detergent efficiency, and therefore washing the clothes with it will result in softer and cleaner clothes.


Improve Appliances’ Life & Efficiency

Without the scales buildup, the electrical appliances can be used for a much longer period of time, saving you lots of money and hassle to get a new one.

All the household appliances will also be operating at max energy efficiency – cheaper electricity bills every month.


Cleaner Surface

Soft water will not leave any stain or scale buildup on floors’ and fixtures’ surface – no more cleaning session for limescale.


Hard Water & Soft Water: In-Depth Understanding

Let’s take a deeper look into hard water and soft water like what’s the differences between them, how to classify them, what’s their advantages and disadvantages, and how they compared to each other.


What is Hard Water

Hard water refers to the water with a high concentration of minerals, mostly calcium, magnesium, iron, potassium, and manganese.

While these minerals are essential to maintain body health, at the same time they also cause many headache problems to your whole water-related infrastructure, household appliances, and your body health.

The hard water can come from both municipal and domestic wells.

The soft rainwater travels through the ground and picks up minerals like calcium and magnesium from minerals deposits and stones along the waterways before reaching our main plumbing system, and that’s how hard water is created.

Not sure whether your water is hard or not?

These are some of the traces of hard water:

  • Formation of whitish scale and cloudy film on the floor surface
  • Accumulation of scale inside electrical appliances like water heaters, boilers, kettles, dishwashers, and washing machines
  • A decrease in soap, shampoo, and detergent lathering
  • Increasing electricity bill

Or you can simply test your water with a hardness test strip.

Note: It’s the hardness test strip and NOT a TDS test meter, TDS value is based on the overall conductivity in water and NOT specific to the calcium and magnesium ions, so it’s NEVER accurate.


What is Soft Water?

Soft water refers to the water with a low concentration of certain mineral ions, particularly calcium and magnesium and followed by iron and manganese.

The soft water can occur naturally or produce by water softeners. 

The water produced through the water softening process is also called ‘softened water’, which is the more accurate term, and softened water usually contains a greater amount of sodium ions than soft water.

The increased level of sodium content is due to the ion-exchange process used by water softeners, which exchange the calcium and magnesium ions in hard water with sodium ions to effectively reduce the hardness level and prevent limescale formation.

Note: Water produced by a water descaler is still the hard water (high concentration of calcium and magnesium ions) and not considered as soft water.

Some of the benefits of using soft water (or softened water) are:

  • No calcium scale deposits in water heating appliances like water heaters and boilers
  • No soap residue to scum from washing
  • Enhanced soap, shampoo, and detergent lathering

How to Classify Soft Water and Hard Water?

Different countries may have different classification of water hardness, but for the United States, soft water should contain less than 3.5 grains per gallon (or 60 milligrams per liter) of calcium carbonate.

In the US, hard water is classified for water with more than a certain amount of calcium carbonate concentration in water:

  • Soft – below 3.5 grains per gallon (<60 mg/L)
  • Moderately Hard – 3.5 to 7 grains per gallon (61 to 120 mg/L)
  • Hard – 7 to 10.5 grains per gallon (121 to 180 mg/L)
  • Very Hard – above 10.5 grains per gallon (>180mg/L)

In fact, most states in the United States are using very hard water, and that’s the reason why most households in the US need a water softener.

water hardness map in the United States (US) image

Hard Water vs Soft Water: The Differences

Let’s take a deeper look into hard water and soft water like what’s the differences between them, how to classify them, what’s their advantages and disadvantages, and how they compared to each other.


Hard Water

It has minerals like calcium and magnesium that are essential for body health.

Some people may prefer the taste of hard water over soft water due to the mineral contents, and softened water is slightly salty in contrast.

Symptoms of Hard Water

Here are some of the common symptoms of hard water:

  • Spots and residues on sink and dishes
  • Soap scum and cloudy film on the surfaces of bathroom floors and fixtures
  • The rough feel of clothes and with whitish residue spots
  • Reduced soap effectiveness and lathering
  • Scale build-up in household appliances and pipes
  • Hot water appliances take a longer time to heat up
  • Whitish mineral deposits on faucets and fixtures
  • Reduced water pressure and flow rate
  • More expensive electricity bill
  • Dry and itchy skin
  • Dull and inelastic hair
Advantages of Hard Water:
  • Better water taste
  • Rich in minerals
  • Low sodium content
Disadvantages of Hard Water
  • Leave spots and stains on sink and dishes
  • Make clothes feel dull and rough, and with whitish residue
  • Consumes more electricity due to reduced energy efficiency of appliances
  • Cause scale build-up inside appliances and damage the components
  • Leave soap scum and cloudy film on bathroom floors and fixtures
  • Cause dry and itchy skin
  • Cause dull and flat hair
  • Reduce water pressure

Soft Water

Soft and softened water is preferred by most people due to its benefits.

Soft water allows you to perform daily household tasks more efficiently, particularly washing and cleaning. Soap, shampoo, and detergent will lather much better and make the cleaning and showering session more effective and smooth.

The dishes will be super clean without any soap scum or residue, the same thing happens for your sink, fixtures, faucets, and more.

How good is it!? Does any mum here agree with me?

You’ll also notice the lifespan of your household electrical appliances last much longer than before and seldom need any repair.

Aside from fixtures and appliances, soft water is also beneficial to you!

Your skin and your hair will see the most significant improvements after changing from hard water to soft water.

After showering with soft water, your skin will be moist and vibrant, let’s make dry and itchy skin a thing of the past, you don’t deserve to suffer this!

Not only that, but your hair will also feel elastic and smooth as well!

As softened water has a higher amount of sodium, so it’s not suitable to drink regularly, especially for people on a low sodium diet and with circulatory or heart problems.

Again, sodium is essential minerals for the body, but excessive intake always comes with some consequences and is not recommended.

But even if it’s not softened water, you should always drink filtered water, and I highly recommend Reverse Osmosis system for the last point of water filtration before drinking, simply because it’s the best water filtration system in the market.

Advantages of Softened Water
  • Extend the life of electrical appliances
  • Reduce energy bill
  • Improve soap lathering and make the cleaning process more efficient
  • Gentle to skin and hair
  • Prevent scales build-up
  • Will not clog the water pipes and fixtures
Disadvantages of Softened Water
  • Higher sodium content
  • Not suitable to drink regularly
  • May cause circulatory and heart problems if drank it frequently

Hard Water vs Soft Water: Which One is Better?

For consumption, neither are ideal for direct drinking. But hard water does have the edge in drinking purpose over softened water due to the minerals content.

Therefore, the ideal solution is to use softened water for all purposes except drinking and install a point of use water filter solely for drinking and cooking purposes.

Whereas for most other household purposes, softened water is far better than hard water.

If you have an extra budget, a water softener plus a RO water filter and a whole house water filter is the ideal option for a complete house water solution.

Otherwise, you may use a water softener with a bypass valve so that you can bypass the hard water for drinking and cooking purposes, and use the softened water for the rest of the household purposes.


Hard Water Solution

There are three solutions for hard water, the most effective way is to install a water softening system, the second solution is using a water descaling system, and the third method is manual cleaning.


1. Water Softening System

Installing a water softener for your house is the most effective way to get rid of hardness and soften your water.

The system effectively exchanges all the calcium and magnesium ions in the water with sodium ions inside the resin bed via the ion-exchange method, and the whole process from turning hard water to soft water is called regeneration.

There are two types of regeneration methods – timer and water usage.

Timing regeneration will regenerate soft water based on time, like every hour, and usage regeneration will regenerate soft water based on water usage.

I highly recommend the latter because it’s a more efficient process that can save you 50-60% of salts and water, all water softeners featured in this article are using regeneration based on actual water usage and not clock.

The sodium ions used for the ion-exchange process are supplied from the salt bags, so once the salts are used up, you’ll have to replace the salt bags for your water softener.

The 2 Types of Water Softener

There are two main types of water softeners in the market:

  • Salt-based water softener
  • Salt-free water softener

Salt-Based Water Softener

This is the most common type of water softener in the market, they are classic, popular, widely-used, and highly effective in treating hard water.

The salt-based water softeners use a water treatment process called ‘ion-exchange’ to exchange the calcium and magnesium ions with sodium ions to produce softened water.

A salt-based water softener is still the most effective method to remove water hardness, it can effectively treat even the extremely hard water that has the hardness level of beyond 100 grain per gallon.

For families with high water consumption, there are dual tank water softeners to meet your needs too.

Some of the best water softeners for well water (salt) in the market are:


Salt-Free Water Softener

Since salt-based water softeners are so effective, then why are there salt-free water softeners in the market?

Well, because salt-based water softeners are not perfect.

Due to some disadvantages like altering water taste and producing wastewater (brine), some people prefer to use the salt-free water softeners.

Technically, a salt-free water softener is a water conditioner and not a water softener because what it does is conditioning the hard water so that the hardness minerals (calcium and magnesium) will not form any build-up deposits when coming in contact.

The water conditioned by a salt-free water softener is still ‘hard’ water as the calcium and magnesium minerals are not removed from the water, but these minerals are converted to a crystal form and will not bond together and stick to any surface to form mineral deposits.

How Non-Salt Water Softeners Prevent Scale Formation

The most common technology used in salt-free water softeners is called Template Assisted Crystallization, a method to transform calcium and magnesium minerals into crystal form that stays suspended in water and will not form any scale build-up.

In short, salt-free water conditioners prevent the formation of scale buildup and not remove them. You’ll still see the white mineral deposit, but rest assured they can be cleaned off easily with simple wipe.

The salt-free water softeners are not suitable for households with extremely hard water as they can only treat water with hardness up to 20-25 grain per gallon.

Here are some of the best salt-free water softeners:


2. Water Descaling System

The water descaling system is an alternative to water softeners in solving hard water problems.

Same as salt-free water softeners, water descalers will not remove the calcium and magnesium minerals from water but transform them into a form that will not attach to the contact surface instead.

The goal of a water descaler is not to soften the hard water, but simply prevent the scale build-up, which is the main concern of hard water.

There are 3 popular types of water descaler:

  • Electromagnetic Water Descaler
  • Physical Water Descaler
  • Additive Water Descaler

Electromagnetic Water Descaler

Electromagnetic Water Descaler images

The electromagnetic water descalers (also known as electronic water descalers) use a strong magnetic field generated by electrical energy to treat the hard water flowing through the pipe and change the minerals’ properties.

While electronic water descalers do not soften the water, they do the job in preventing scale formation.

They are economical alternatives to water softeners.

Some of the advantages of electromagnetic water descalers are:

  • Will not interfere with your piping system (They attach on the pipe)
  • Easy to install
  • Maintenance-free

Here are some of the best electronic water descalers:


Aside from the electromagnetism method, there are also electronic water descalers that use other types of technology such as electrical induction (eg: HydroFLOW HS38 Water Descaler), which use an electrical current to precipitate the water hardness.


Physical Water Descaler

The physical water descaler uses a Scale Control Media (SCM) to speed up the natural tendency of hard minerals to crystallize so that they can’t attach on pipes or surfaces to form scales.

While it can’t remove the calcium and magnesium minerals, it transforms them into inactive microscopic particles that are harmless to pipes and appliances.

For instance, the Aquasana Rhino is a whole house water purification system that comes with SCH media to prevent scale forming.


Additive Water Descaler

The additive-based water descalers use food-grade polyphosphates to bind calcium and magnesium minerals to inhibit scale build-up.

If you simply want a small water descaler to protect your hot water appliances, they can make a good fit.

The best additive water descaler is the 3M Aqua-Pure Scale Inhibition Water System.


3. Manual Cleaning

This is a less effective and time-consuming way.

If there are some reasons that make water softener or water descaler not possible for you, then manual cleaning is the only option left.

You can use an all-purpose cleaning liquid or vinegar mixed solution to remove the scale buildup.

As prevention, make sure you remove all the water on the floor surface after each shower with a squeegee.


How to Choose the Best Water Softeners for Well Water (Buyer Guide)

How to Choose the Right Water Softener image

Here comes the most important question – which water softener is the best for me?

In this section, I’ll share with you the best approach to choosing the best water softener for your home.


Factors to Consider a Water Softener

Before looking at the features of water softeners, here are something you may need to take into consideration:

  • Reliability
  • Spare parts
  • Seller location
  • Maintenance


For an expensive system like water softeners, give priority to established water softener brands with proven technology and a good reputation.

If they can survive in this industry for many years, it’s more likely they have a great quality product.

Fleck, APEC, DuraWater, Whirlpool, AFWFilters, Pentair, and OneFlow are some of the best water softeners brands in the market.


Spare Parts

If possible, get a water softener built with non-proprietary components as it’s easier to get the spare parts for repair.

Otherwise, if the company discontinued the particular water softener or went disappeared, you may never be able to find the brand-exclusive spare parts for repair.


Seller Location

For bulky and heavy products like water softeners, it’s highly recommended to buy from local sellers.

First, it’s easier to return in case something went wrong, and the second is customer support.



Look for a water softener that is easy to service and maintain, you’ll never regret it.


Important Features of Water Softeners

Here are some of the key features that determine whether a water softener is right for you:

  • Resin capacity
  • Regeneration
  • Iron reduction
  • Available space
  • Bypass valve
  • Resin crosslinks

Resin Capacity

Generally, the larger the resin capacity, the less frequent the water softener needs to regenerate, and last longer.

For large families, aiming for a water softener with high resin capacity or a dual tank water softener is a better choice.

For small families, the only drawback for a high capacity water softener is the cost, so if you don’t mind paying the additional cost, go for higher capacity within your budget.



Get a water softener that regenerates soft water based on water usage and not time, it’s more efficient and can save you lots of salts and water.

For a timed system, the water softener’s resin will regenerate based on the time setting, like every 3 days, so even if you only use a little bit of water, the system will still regenerate the soft water and wasted the salts and water, but if your water usage is high, you are likely to run out of soft water.

But for a metered system, the resin will regenerate only after a fixed amount of water is used to ensure you always have the soft water and saves salts and water when your water usage is low.

Here are some great water softeners with trusted Fleck digital metered control:


Iron Reduction

If your water is hard and contains a high concentration of iron, it’s recommended to get a water softener that specializes in iron removal to prevent red-brown stains on your fixtures and appliances.

Here are some of the best water softeners for iron removal:


Available Space

As the water softener is huge in size, so make sure you have done the measurement before getting a water softener.

You can check the physical measurements of a water softener easily on the internet or from the sellers.


Bypass Valve

The water softener bypass valve allows you to bypass the water softening system to let hard water flow through.

This is an optional feature but good to have, for purposes like servicing or when hard water is needed.


Resin Crosslinks

The crosslink is the standard indication of resin.

Water softening resin with higher crosslinks will have the following improvements:

  • Larger capacity
  • Withstands high-frequency regenerations
  • Can operate at a higher temperature in the presence of chlorine or chloramine,
  • More chlorine tolerant.

8% crosslink is the industry standard, there are also 6%, 10%, and 15% crosslinks.

In most of the cases, 8% crosslinks resin is fine.

But if you are using highly chlorinated water (city water), it’s recommended to get a water softener with 10% crosslinks for higher durability against chlorine or chloramine.


How Do Water Softening Systems Work?

How Do Water Softening Systems Work image

Water softening systems do not remove any contaminants in water, they only exchange the mineral ions or transform the mineral ions’ property to prevent scale build-up.

To remove contaminants in water, you have to use a water filtration system.

Curious about how water softening systems work?

Here’s the water softening processes for each type of water softening systems.


How Do Salt Water Softeners Work

The main culprits of scale build-up are calcium and magnesium.

A salt-based water softener exchanges calcium and magnesium ions from hard water with sodium ions from resin to soften the water.

Sodium ions do not form any buildup or interfere with the lathering action of soap.

Initially, a few cubic feet of resin that contain many tiny negatively-charged beads that are used to attract dissolved positive ions in the water are covered with positively charged ions (usually sodium). 

When hard water flows through the water softener’s resin tank, the calcium and magnesium ions from hard water will attach to the resin and the sodium ions are then released into the water to maintain the balance of electrical charge on the resin. This happens because calcium and magnesium ions have a stronger positive charge than sodium ions.

Progressively, the majority of sodium ions are released to the water and the resin is saturated with calcium and magnesium ions.


Water Softener Regeneration Steps

Then, the water softener undergoes a regeneration process to rinse and renew the resin with salt water (sodium chloride). The high concentration of sodium ions will replace the calcium and magnesium ions in the resin and make the resin covered with sodium ions again.

Lastly, the calcium and magnesium ions will be flush to the drain together with the salty wastewater, and the system is back to normal operation.

There are two types of tanks in the salt-based water softener, first is the main resin tank that is used to remove the hardness minerals, and the second is the brine tank that is used to keep salts and produce brine for resin regeneration.

Depending on your water usage, you’ll have to add a few bags of salt (sodium chloride) to the water softener brine tank every few days, weeks, or months for the regeneration processes.

Each cubic foot of resin can treat about 3,200 gallons of hard water, which is 10 grains per gallon hardness as defined by WQA, and the regeneration process adds about 750 milligrams of sodium to each gallon of water.

For people on a low sodium diet, you may use the potassium chloride salt instead but it is more expensive than sodium chloride salt.

Results: Softened water, prevent scale buildup and clogged pipes, extend the lifespan of appliances, improve soap lathering, enhance skin and hair, and slightly salty water.


How Do Salt-Free Water Softeners Work

No-salt water softeners, or better referred to water conditioners, do not soften water, they use technologies like Template Assisted Crystallization to transform the calcium and magnesium minerals into crystal form that will not bond and stick to any surfaces to form scale build-up.

They condition hard water to prevent scale forming.

As a result, the water is still hard as none of the hardness minerals are removed from the water, but what changed is that those minerals will not form limescale in your appliances and pipes.

And that’s the main problem with hard water.

It has less maintenance work than salt-based water softeners.

Pair it with a water filtration system for complete whole-house protection.

Results: Prevent scale buildup and clogged pipes, and extend the lifespan of appliances.


How Do Dual-Tank Water Softeners Work

The dual-tank version works the same as salt-based water softeners, with two added benefits which are larger capacity and you get non-stop soft water supplies due to alternating tanks.

A single-tank salt-based water softener needs to pause the operation for the regeneration process, and the dual-tank water softener solved this issue by using the alternate tank while one tank is undergoing regeneration.

Results: Continuous softened water, prevent scale buildup and clogged pipes, extend the lifespan of appliances, improve soap lathering, enhance skin and hair, and slightly salty water.


How Do Electromagnetic Water Descaler Work

The electromagnetic water descaler, often used as no salt alternative to water softeners, uses a strong magnetic field generated by electricity energy to alter the hardness ions’ property so that they won’t stick on surfaces.

They are installed on the outer area of the pipe and coiled the pipe with wires or bands.

They will not interfere with your existing piping system nor have any direct contact with the flowing water.

Results: Prevent limescale buildup and clogged pipes, and extend the lifespan of appliances.


How Do Chemical Water Softener Work

This type of water conditioner uses chemical substances like Polyphosphates to effectively bind calcium and magnesium minerals in hard water to prevent them from precipitating and form scale build-up.

Besides, the Polyphosphates will also form a thin protective layer on the metal surface to prevent corrosion, which is great for hot water appliances.

Results: Prevent limescale buildup and clogged pipes, extend the lifespan of appliances, and prevent corrosion.


How to Test the Water Hardness?

There are few ways to test and know your water hardness, and they are:

  1. Water Hardness Test Kit
  2. Foam Test
  3. Bathroom Fixtures Observation

1. Water Hardness Test Kit

The most accurate way is to purchase a water hardness test kit or test strip to run the test.

With this method, you can know whether your water is hard or soft and how hard it is.

Note: It’s the water hardness test kit and NOT the TDS meter. TDS meter is used to estimate the total dissolved solids through the water conductivity test and is not for water hardness.


2. Foam Test (Lathering Test)

Foam test can give you an idea about the type of water – hard or soft.

As we discussed earlier, hardness will reduce lathering.

To do the foam test:

  1. Fill up half of a transparent bottle with water.
  2. Add 4-5 drops of dishwashing or detergent liquid into the bottle and close the cap.
  3. Shake the bottle for 5 seconds.
  4. Observe the foam

If the foam stays for a long period, it’s soft water; If the foam dissipates quickly, it’s hard water.


3. Bathroom Fixtures Observation

Another way to know the type of water is through observation, and you may run the investigation in the bathroom.

Observe carefully to see if there’s any white-colored spots or scale on the surface of your bathtub, shower head, and floor.

If there was any, it’s hard water, if not, it’s soft water.


How to Install a Water Softener (Step-by-Step Guide)

Most water softeners featured in this article are easy to install, you just have to follow the step-by-step installation guide and install it with the right tools and components.

But if for some reason you are not able to install yourself, then you have to hire a professional plumber to come over and install it for you.

Here are the installation steps for water softeners:

  1. Shut off the main water supply.
  2. Locate the inlet pipe (before the house).
  3. Cut the inlet pipe to install valves and pipes.
  4. Install at least 3 valves: Before and after the water softener, and a water softener bypass valve
  5. Double-check the connectors to ensure they are tight.
  6. Connect the water softener brine tank to the resin tank.
  7. Connect the discharge line to the wastewater drain.
  8. Connect the Water Softener

Before we dive into each individual step, let’s take a look at the required tools and components.


Tools and Components for Water Softener Installation

Most sellers will provide you the essential tools and parts for water softener installation.

However, it’s good to have some useful plumbing tools and parts with you in case the quality of the provided components is bad.

Here are some of the basic plumbing tools that you may want to prepare:

  • Measurement tape
  • Water-tube cutter
  • Plumbers tape
  • Pliers
  • Wrench
  • Soldering tool
  • Teflon tapes
  • Pipes (PVC or Copper)
  • Tee valves

What to Consider Before the Water Softener Installation

Before you start installing the water softener, you have to decide the location first.

Most of the time, you should install a water softener on the main water line after the pre-sediment filter and whole house water filtration system, and before entering the house.

The common places to put the water softener are the utility room, garage, and basement. Unless the water softener is heavy duty and made to survive under harsh conditions, you shouldn’t place it in an open area with direct sunlight.

Make sure the designated location has enough floor and wall space to install the water softener.

For saltwater softener, make sure the location has a way to drain the wastewater, and for electronic water descaler, make sure a power outlet is prepared.


How to Install a Salt Water Softener

Here are the detailed steps to install a salt-based water softening system for your house.


Step 1: Shut Off the Main Water Supply

First, turn off the main water supply valve and drain out the water inside.

This is a crucial step and makes sure you’ve done it before you start doing anything crazy.

Step 2: Locate the Inlet Pipe

Next, locate which part of the pipe you want to install the water softener, it should be after the whole house water filtration system (if any) and before entering the house.

Step 3: Cut the Inlet Pipe to Install Valves and Pipes

Now, put a basket below the cutting spot to collect any residual water and cut the inlet pipe with a tube cutter.

Step 4: Install At Least 3 Valves 

The 3 water valves are necessary for future maintenance.

Install one valve before the water softener to control the water entering the system, and one valve after the water softener to control the water exit from the system.

Lastly, install a valve that parallels to the water softener. This valve is used to bypass the water softener during servicing or in case you need hard water for certain purposes.

While some water softeners come with a bypass control valve, you’re still encouraged to install one.

Step 5: Double Check the Connectors

After you installed the valve, do a quick check to make sure all the connectors are tight to prevent leaking later.

Step 6: Connect the Resin Tank to the Brine Tank

Use the pipe provided by the seller to connect between the resin tank and brine tank.

Step 7: Connect the Discharge Line to the Wastewater Drain

Connect the discharge line to the wastewater drain, which can be a floor drain, sump drain, or utility tank.

Make sure the discharge line is lower than the overflow fitting.

Step 8: Connect the Water Softener

Connect the water softener carefully to the inlet and outlet pipes and tighten all the connectors and parts.


How to Install an Electromagnetic Water Descaler

The installation of an electronic water descaler is simpler than the water softener due to its size and working mechanism.

Please note that not all pipe materials are compatible with electronic water descalers, so please check with the seller before buying.

Electromagnetic water descalers will not interfere with your pipe system as they are just installed on the main water pipe to do the work.

Here are the installation steps:

  1. Install the electromagnetic water descaler on the wall near the pipe
  2. Coil around the pipe with wires/bands according to the user manual
  3. Turn on the power supply to start the water conditioning process

Easy peasy.


Why Should You Buy Water Softener from Amazon?

Because the water softener price on Amazon is much cheaper compared to the local contractors and salesmen.

For the same product, the quotes you get from the contractors can be 1.5 to 3 times higher than the price on Amazon.

Even if you don’t want to install the water softener by yourself, purchasing one from Amazon and hire a professional plumber to install is still cheaper in total.


FAQ for Water Softening System

1. If softened water safe to drink?

Yes, it’s safe to consume, but it’s not recommended to drink regularly due to higher sodium content, especially for those who are on a low sodium diet.

2. What is the crosslink of water softener resin?

The crosslink is the standard indication of water softener resin, higher crosslinks have a larger capacity, can withstand high-frequency regenerations, can operate at a higher temperature in the presence of chlorine or chloramine, and is more chlorine tolerant.

3. Should I use 8% or 10% crosslinks resin?

Most water softening resin has 8% crosslinks and the upgraded version of resins has 10% or higher.
If your water is chlorinated (city water), it’s better to go for 10% crosslinks resin for stronger endurance against chlorine, but the 8% crosslinks resin is fine too.

4. Will a water softener alter the taste of water?

Yes. The softened water will be slightly salty compared to hard water.

5. Can a water descaler soften the water?

No. Water descalers only condition the water so that the hardness minerals will not form any scale build-up.

6 thoughts on “The 16 Best Water Softeners for Well Water & Home 2021”

  1. I have extremely hard water. The scale on the plumbing fixtures was thick and so hard I couldn’t chisel it off. My hair was brittle and soap did not suds up. I put a whole house filter in and it clogged in a few days. Bought an expensive electronic descalers and it burned up after 4 months. Took a chance on the water conditioner and saw a big difference after about a week. within 3 days of installing, I noticed I had suds when shampooing my hair. After a month the hard scale crumbled and fell off the fixtures and they were shiny once more! My dishwasher is working much better and clothes and cleaner and smell fresh when they come out of the laundry. My hair feels like hair, not hay! I also have seen a big difference in my heating and hot water cost.

  2. I just called Eddy water Descaler and a gentleman named David called me back within an hour. As our conversation progressed come to find out this is not intended to help me as much with my iron problem. Well, long story short he is refunding my purchase price. I was really impressed with the unit on a client’s house(I’m a general contractor) and will continue to install these units on homes I build in the future.

  3. I love iron Pro 2 My absolute favorite appliance in the kitchen. It works so well, it is quiet, easy to use, makes fantastic tea, and really is a tea lover’s dream. I’m primarily a black tea drinker and for that, the variable temp control is less useful as one can boil water in many other ways, but the constant temperature during steeping and the convenience of setting it and walking away til it is done is great.

  4. Iron Pro 2 is also working great. We have city water, that comes from a well, so it’s still hard water. We have a family of 5. To do the math properly, avg 75 gal per person per day. = 375 gallons At a 19gp (325ppm) grain hardness. means we need 7125 grains per day. For a 1 week charge, we need 49,875 grains. So this provides enough capacity.

  5. Whirlpool WHESFC ProSeries is working nicely and does use less salt like they said it would. Pretty quiet when it recharges in the middle of the night. Pretty easy to install as well!!! Don’t let these plumbers try to gig you on install, it’s not worth the $275 the guy told me it would cost for him to install!
