12 Best Whole House Water Softener Systems Reviewed & Ranked

F or those who are uninformed on the topic, we will provide a quick explanation of what hard water is. For this classification to exist, the water must contain a minimum of 60 milligrams of dissolved calcium and magnesium. In fact, to give you the full picture of how water is classified according to general guidelines when it comes to softness/hardness, know that 0 to 60 mg/L is considered soft water, 61 to 120 mg/L is moderately hard water, 121 to 180 mg/L is hard water, and everything above 181 mg/L is considered as very hard water.

There are simple ways to tell if you are dealing with hard water, without having to spend money on lab testing or procedures of the sort. According to the Water Quality Association, some of the symptoms that indicate water hardness levels are within unsafe parameters include:

• Visible scale build-up in water-fed appliances, faucets, sinks, and tubs;
• Dishes and glassware with clear mineral deposits on them;
• Stiff laundry that demands a higher usage of fabric softener during washing;
• Higher soap usage for all cleaning and washing tasks;
• It lasts longer and takes more effort to remove soap curd from the tub or shower;
• Excess scale build-up in pipes and water-fed appliances causes higher energy costs.

Now that you know a bit more about what hard water is and how to spot it at a glance, let’s cover the topic of what effects it has. While there are no serious health risks associated with hard water consumption, it does worsen symptoms in people who have eczema, and it causes dry skin and hair. The more worrying issues with high levels of water hardness are – unpleasant water taste, frequent plumbing repairs, harder water flow which causes a rise in the water bills, white spots on dishes and glassware, faded clothes, stained sinks, stained tubs, and scale buildup on plumbing fixtures and appliances.

To tackle the issue of hard water, a water softener is a solution since it removes hardness-causing agents so that scale deposits and other issues don’t emerge. These systems either base their operation on a salt-based or salt-free technology, each with its own set of benefits and drawbacks. However, they do have one thing in common – efficiency in softening the water that runs through your pipes.

Water Classification According to Hardness Level

While there is a mixture of the water’s pH, temperature, and minerals dissolved in water that indicate the precise level of hardness, which means that a single-number scale cannot be used for the classification of water in accordance with its softness/hardness level, the U.S. Geological Survey has devised a classification table that helps identify water type based on this single trait more easily. This is how it looks:

Soft water:

mgG-CaCO3/L	mmol/L	dGH/°dH	gpg	ppm
0 – 60	0 – 0.60	0 – 3.37	0 – 3.50	0 – 60

Moderately hard water:

mgG-CaCO3/L	mmol/L	dGH/°dH	gpg	ppm
61 – 120	0.61 – 1.20	3.38 – 6.74	3.56 – 7.01	61 – 120

Hard water:

mgG-CaCO3/L	mmol/L	dGH/°dH	gpg	ppm
121 – 180	1.21 – 1.80	6.75 – 10.11	7.06 – 10.51	121 – 180

Very hard water:

mgG-CaCO3/L	mmol/L	dGH/°dH	gpg	ppm
≥181	≥1.81	≥10.12	≥10.57	≥181

Now that you are properly informed about what concerns water hardness, let’s move on to what you actually came here for. And that is to learn what the best whole house water softeners are. Only with the help of these systems can you finally enjoy soft water that doesn’t provoke irritations, dry skin and hair, and doesn’t affect pipes and water-using appliances. Without further ado, let’s rate, rank, and review the products worth spending your cash on.

---

Providing naturally softened water through a friendly process that doesn’t involve the use of salt, the Pelican entry was an inevitable pick. Are you wondering how it works? Well, let us explain it in short. The media has calcium carbonate crystal structures on the surface that have the role of attracting the excess dissolved hardness and removing it through integration with the aforementioned structures.

It is 100% Eco-friendly because it doesn’t produce any water waste, and it doesn’t draw on electricity to run either, which means that it adds $0 to the electricity bills to provide softened water. Maintenance-wise, you won’t have a lot of work on your hands as you just have to remember every 6 to 9 months to change the sediment filter.

The maximum hardness it can tackle is 1282 milligrams per liter, an aspect you must take into consideration as signs of it underperforming could indicate that your needs surpass its capabilities. Compatible with a maximum flow rate of 15 GPM, it is recommended for homes with 4 to 6 bathrooms. From this point of view, it surpasses the top-rated Aquasana SimplySoft since it flaunts a flow rate a bit more than double as large.

In the package, aside from the system and the pre-filter are included the mounting hardware of the pre-filter system, as well as the bypass valve and 1” fittings. There is an installation manual included that provides the info you need to get through the installation without any hiccups along the way.

4. PRO+AQUA 80,000 Grain Capacity Water Softener

Summary: This salt-based dual-tank softener uses powerful ion exchange resin to treat medium to high water hardness levels. As soon as you install it, you will notice changes in the way your hair and skin look and feel since damaging minerals and chemicals won’t bond to them anymore. Laundry will look better too, and all of your water-using appliances will receive a boost in their performance. Best of all, this is an 80,000-grain capacity model that needs far less in terms of maintenance compared to the other salt-based systems we reviewed.

---

Of all salt-based water softeners, this PRO+AQUA product might just be the best. It’s a dual-tank system that uses powerful ion exchange resin to treat medium to high water hardness levels, in turn helping your water-using appliances run better, protecting the piping system of your home, and helping your skin and hair look better while amping their health.

The 80,000-grain capacity is a perk on its own since it makes the system perfect for large households where water is extremely hard. This large capacity also makes it efficient to treat hardness levels of up to 110 GPG as long as the maximum number of users is 4 people. Although it’s a dedicated water softener, it can remove a small amount of iron from the water too, namely 2 ppm.

The high capacity combined with the 1-inch high-flow threaded ports assures of the fact that it allows fast water flow. Therefore, you won’t see any drops in water pressure regardless of how many taps are running simultaneously. To give you a better idea of how well it performs in large households, know that it puts out 12 gallons of soft water per minute. This makes it perfect for homes with multiple bathrooms, hands down.

The brine tank is very large, holding approximately 120 pounds of salt. For a family of 4, refilling the brine tank is needed once every 2 months or so. It doesn’t require regeneration as often as its competitors do, saving on water and salt usage due to this. Best of all, the programmable digital meter automates the regeneration process to make your effort toward upkeep as little as possible.

Before we end the review, we want to warn you about one thing – don’t install it yourself if you don’t have plumbing experience/knowledge. This system requires connection to the main water line and drain, so there are changes to be made to the plumbing system. For this reason, we recommend expert installation if you aren’t experienced. Other than this, we have nothing negative to say about the PRO+AQUA softener. It’s a softener that delivers reliable performance and promises little water and salt waste.

PRO+AQUA 80,000 Grain Capacity Water Softener Specifications Sheet
Type: Salt-based	Media Replacement: 80,000 grains
Maximum Hardness Removal: 110 GPG	Flow Rate: 12 GPM

5. 3M Water Softener System 3MWTS100

Summary: The standout trait of this 3M water softener is that, unlike other salt-using systems of the sort, it doesn’t produce as much water waste in its operating process. To grant this perk, it monitors water use and employs regeneration only when needed. Water softening efforts are significantly superior to that of most units available, which is why it ranks so high despite the smaller capacity and higher asking price. After all, it’s the performance that matters most, and the 3M really knocks it out of the park when it comes to this particular aspect.

---

Specialized in reducing scale and water hardness, the 3M 3MWTS100 is a salt-based system with a 28,100-grain capacity that you can count on to make a significant difference in water quality if you source your water from the well. What we like most is that it reduces water usage by metering use and following through with the regeneration process only when necessary, saving you water, energy, and salt so that operational costs are minimized.

Another mention-worthy detail related to the regeneration process is that the resin re-circulator lifts the resin from the bottom of the tank to the top. As this happens, there is a scrubbing action that takes place between resin beads, resulting in a more efficient regeneration and extended media lifespan.

Unlike other systems, it doesn’t require much in the way of maintenance, especially considering that it features a multi-level salt shelf which serves the purpose of keeping dirt and debris away from the drawing area, resulting in reduced valve upkeep.

The system even shines in the durability department considering that the tank is solid due to the high-density polyethylene and composite fiberglass construction. The peak operating temperature it withstands is 100 degrees Fahrenheit, while the operating pressure ranges from 20 to 125 PSI. Lastly, we mention that the product is covered with a 5-year warranty for the valve body and electrics, and a 10-year warranty for the tanks (filter and salt brine).

6. Discount Water Softeners Genesis Duo

Check Price at Amazon

Summary: This is one of the most sought-after salt-based softeners since it needs an insignificant amount of salt for the regeneration process and wastes little water too. The Genesis Du is a must-have if you are looking for a great deal not only when it comes to the asking price but running expenses as well.

---

Recommended for large-sized households, this 48,000-grain capacity system uses salt to ensure scale buildup won’t happen ever again. It features a large-size brine tank that can hold a maximum of 300 pounds of salt, and tank tux jackets that reduce sweating to upkeep performance are included.

It relies on carbon to reduce chlorine, so if your municipality tends to abuse chlorine use to tackle bacteria and other harmful contents, it will deal with the chemical to solve issues related to the taste and odor it tends to leave. The only other water softener that competes with it when it comes to chlorine reduction is the ABCwaters 5600sxt, so if you’re looking for an alternative, this is the closest one performance-wise.

One of its biggest highlights is the up-flow brining that ensures an optimal amount of salt is used for the regeneration process to save on maintenance and operational costs. When a week passes since it hasn’t been used, the stagnant water is flushed automatically by the System Refresh to ensure that bacteria won’t grow in it.

The recharge mode, one of its most useful features, guarantees that in times of need when heavy water usage is due, you will be provided with soft water. On the display, it shows key information through rotation, including:

• Flow rate;
• When the last regeneration process took place;
• How much volume is left until the next regeneration process ensues.

Lastly, we mention that lifetime backing is provided for the resin tank by the manufacturer, while the control head is warranted to be free of defects (or fixed/replaced otherwise) for the first 10 years as of making the purchase. Customer support is on par too, so any question you have regarding this water-softening system will be quickly answered.

7. ABCwaters 5600sxt

Check Price at Amazon

Summary: Producing little water waste in the process and built to provide years of use without hiccups along the way, the ABCwaters 5600sxt might not be the cheapest salt-using softener you will find but it’s definitely one of the most reliable options when it comes to hardness reduction efficiency.

---

A more affordable option, this system is a budget-smart solution to upkeep appliances, keep the pipes clean, and preserve skin and hair health. Moreover, it uses salt in the process too, which adds to its efficiency.

As the recommended service flow for it is up to 12 GPM, it is recommended for houses where up to 5 people live. It boasts a 48,000-grain capacity, and as the resin it utilizes is 10% cross-linked, a longer lifespan is granted.

What we especially like is the high activity carbon media which boasts an up-flow design and ensures efficient filtration of pollutants like chlorine, pesticides, THMs, chloramines, and more, without the necessity for backwashing ever existing. If 14 days have passed or when 0 gallons are remaining, it automatically regenerates to upkeep its performance.

Of course, we cannot overlook the fact that it uses the high-end Fleck technology which keeps you aware of how the unit’s process is going and notifies you regarding water quality aspects of interest. It provides you with a countdown on the gallons used and remaining so that you always know what to expect.

8. Aquasure Harmony Series 48,000 Grains

Check Price at Amazon

Summary: If you’re on the hunt for a salt-based system to reduce water hardness ASAP, the Aquasure Harmony is an option you definitely must consider. For significantly less than $800 (around $500 if you catch on sale), you can say goodbye to scale formations on water-reliant appliances and pipes. Your tub or shower, even the sinks won’t have those pesky deposits on them anymore. Best of all, this unit meters water use and performs backwashing at the right moment for optimum performance, so there’s little asked of you – just set it up, fill the salt tank when needed, and that’s all.

---

9. Tier1 Everyday Series 48,000 Grain

Check Price at Amazon

Summary: While it might not be the most user-friendly softening system since the installation procedure isn’t explained in proper detail in the manual and the control panel is a bit difficult to figure out even for those who aren’t first-time owners of a product of the sort, it’s still a worthy option to consider since it rises to expectations performance-wise. It does the promised job of reducing water hardness quite effectively, and the asking price is significantly smaller than that of similar products, and these are the aspects that matter most in the end, not the difficulty of the setup process.

---

Before it begins the regeneration process, it processes up to 48,000 grains of hardness. When the automatic system regeneration does come into play, it takes approximately 2 hours for it to finish, and in the meanwhile, the water service is interrupted.

The mineral tank measures 10” by 54” and contains 1.5 cubic feet of resin, which are small polystyrene beads that can attract hardness-causing minerals so that these don’t pass on with the water afterward using a negative ionic charge.

The brine tank can hold up to 130 square liters of salt. Woefully, it lacks an indicator to show you when salt levels are low and replenishing is required. The cycle times are fully adjustable, so you can make proper adjustments according to water hardness and family size.

The operating temperature range spans from 40 to 120 degrees Fahrenheit, the peak flow rate is 11.2 GPM, and the operating pressure range spans from 20 to 120 PSI. With a larger capacity than the 3M Water Softener System 3MWTS100 and a better flow rate too, while not as performing when it comes to hardness reduction, it is a viable alternative if your budget doesn’t suffice for this more efficient system. It features a user-friendly LCD that shows all the information you need in regard to operational stats. Best of all, you spare money on the setup process due to the quick connections on the brain and drain lines as this setup makes it an easy DIY project to take up on your own.

10. GE GXSH40V

Check Price at Amazon

Summary: Since it’s a GE product, one of the most renowned brands out there, you can rest assured knowing that this is a product you can count on in the long run. The 40,000 grains capacity water softener might not be the easiest to set up, but once it’s hooked, the difference in water hardness levels is felt almost in an instant. It even consumes less water when compared to competitors, so if you want to be smart about your money, you definitely ought to consider acquiring it.

---

The 40,200-grain capacity system is reliable for the removal of grains, iron, and other hardness-causing agents. It features up-front electronic controls that grant intuitive use. To make maintenance work as easy as possible, the indicator lights let you know when salt levels are low, and replenishing is needed.

It can tackle 125 GPG maximum hardness removal and iron removal of up to 10 PPM. The salt capacity it boasts is 230 pounds to spare you from replenishing it too often. To clear the water of contaminants in the process too, it uses a self-cleaning sediment filter that removes small-size impurities and sediments. One of its main highlights stands in the SmartSoft technology that can learn the water use patterns of your household so that it ensures enough softened water is available at any given moment.

Another neat feature is the Custom Select blending valve that lets you choose the softness level of the water. The Salt Saver technology makes it 34% more efficient when it comes to salt consumption, and it even consumes 35% less water when it runs to be efficient on all fronts. It measures 14.4” in width by 22.4” in depth by 47.6” in height and weighs 105 pounds to make maneuvering it non-problematic during the installation process.

11. Nuvo H2O DPHB

Check Price at Amazon

Summary: The Nuovo H2O is not the best when it comes to softening the water since it’s not as speedy as its more expensive counterparts from this point of view, so if you’re expecting miracles, better look into the Aquasana SimplySoft, Pelican NaturSoft, or ABCwaters 5600sxt instead. However, if you’re looking for a budget-friendly deal and you have a bit of patience, then look no further because this is the right option for you.

---

The Nuvo H2O DPHB provides optimal performance in homes with 2-3 residents that are up to 2000 square feet. Thus, it is a viable candidate for most homeowners, especially considering the reasonable asking price it comes at. What makes us giddy about it is that it doesn’t use salt or electricity in its operation, nor does it waste water, so it’s a 100% Eco-friendly option to consider.

The revolutionary technology behind it lowers the water’s pH level through chelation. How does chelation work? Well, the mineral ions which are at fault for hardness are bound to the chelation agent that keeps them soluble so that calcium, magnesium, and other minerals don’t cause trouble anymore.

It uses 2” by 20” replaceable cartridges that require to be changed after filtering 20,000 gallons of water. Thus, routine maintenance doesn’t come around too often, and it’s not costly either. It provides a 12-15 GPM with 1” ports flow, so chances are that there won’t be shifts in water pressure after installing it.

Negative Effects of Hard Water

There are plenty of ways in which hard water may affect your health as well as your home. Sure, as opposed to contaminated water, it seems harmless, but don’t be fooled as, especially in areas where this is a worrying issue, there are more than enough negative effects to be dealt with, as you will soon learn.

Health Impacts:

• Even in healthy individuals, it increases the chances of cardiovascular disease developing.
• The excess minerals in water increase blood pressure, which takes a toll on your health state.
• In adults, hydration with hard water can lead to reproductive failure and amplify pre-existing issues in this department.
• Increases chances of various forms of cancer to appear, including gastric, colon, ovarian, and esophageal cancer.
• Leads to neurological disorders and diseases.
• Predisposes individuals to develop diabetes.

Skin Problems Caused:

• Dry and bumpy patches of skin appear as a result of the irritation and dryness caused by bathing with water that is too hard for the skin.
• In children, it leads to the development of eczema.
• Cleaning products do not dissolve properly, which causes skin irritations as rinsing is not performed well.

Effects on Your Home:

• Pipes get clogged, an issue that you must tend to for proper water flow in your home. Pipes getting clogged directly affects certain household appliances as well, making them run less efficiently. Thus, not only is there a drop in their performance but utility costs are bound to get higher as a result too.
• The appearance of stains on sinks, showers, and bathtubs.
• The formation of a thick scale on fixtures.
• Dirty appearance of glass showers as they become opaque with time.

Water Softeners Types

Softeners are needed in almost every household, but the search for the right one will lead you down a path that you might not fully comprehend as there isn’t a single type you will encounter but rather multiple ones. While in our article you find salt-based and salt-free systems, there are other two options out there as well, and in the following, we will talk about all four types.

Salt-Free System

The complex procedure through which it reduces hardness involves template-assisted crystallization, which means that minerals are turned into crystals that cannot attach to surfaces. This is more of a conditioning process rather than a softening one but it is still efficient, and it presents a more Eco-friendly functioning, so its popularity is easily explainable.

Pros:

• Not a lot is asked in the way of upkeep work.
• Does not rely on electricity to run.
• Zero water waste.
• As opposed to salt-based models, these come at a more affordable price.
• Installation can be performed by the user with ease to spare money that would have otherwise gone toward professional help.
• No added sodium in your diet, which is good news for those who must avoid salt consumption due to pre-existing health conditions.

Cons:

• Limescale buildup can still occur where water sits for a prolonged amount of time.
• Takes a bit longer to go through with its operation as it relies on transforming the chemical structure of water.

Salt-Based System

It is comprised of a resin bed that exchanges sodium particles for the minerals in the water that passes through it. When the saturation point is reached, the regeneration process ensues where multiple backwashes are used to clean the minerals it has already trapped and sodium particles are replenished so that it continues to work normally.

Pros:

• High effectiveness as it removes minerals.
• Scaling won’t be an issue anymore.
• Less soap used for all activities.
• Higher efficiency and longer lifespan of appliances.
• Plumbing won’t require as many repairs or maintenance work.

Cons:

• Higher costs upfront.
• Salt must be routinely replenished, which implies extra costs.
• Resin bed requires to be cleaned.
• Involves water waste.

Dual Tank System

It is comprised of a brine or salt tank and two resin tanks. It can regenerate on demand and, when one of the tanks reaches its maximum capacity, it automatically switches to the other one so that there won’t exist interruptions in its operational process.

Pros:

• Reduced salt and water use.
• Higher efficiency in its operation is granted by the extra tank.
• Fewer water quality fluctuations.

Cons:

• The extra tank automatically implies higher maintenance costs in the long run.
• As the footprint is larger, it takes up more space.

Magnetic Descaler System

A less conventional system that proves to be more of an alternative rather than an actual solution for reducing water hardness, it isn’t as popular as the aforementioned types as it lacks operational consistency. It is quite similar to non-salt systems, preventing scale buildup up to a point.

Pros:

• Completely hassle-free service.
• No actual installation is required and there’s no interference with the piping system as you just have to coil wires around water intake pipes.
• Reshapes the properties of the minerals it encounters.

Cons:

• The least effective type of softener.
• Newer technology – it hasn’t been perfected yet.

How to Install a Water Softener System

We divided the installation instructions according to the system types as procedures differ. Beware to check the accompanying installation instructions and if there are differences, follow the provided guidelines as certain systems might have special requirements.

Installing a Salt-Based System:

1. Start the procedure by shutting off the water supply to your home.
2. Next, proceed to drain all the water in the pipes.
3. After you are done, shut off the water heater and cut the power to it.
4. Now you can pick where you want to install the system. A small tip – position it before the water heater.
5. Cut into the mainline where you plan to install the system.
6. To guarantee a proper fit, cut the pipes that lead to the bypass valve.
7. Solder the fittings before connecting the valve and the pipe.
8. Using the provided compression fittings, make the connection to the pipes.
9. Clamp the hose to the system, feet it where it drains, and connect the overflow tube and brine tank.
10. Now, make sure you flush out all debris and sediments using the bypass.
11. Plug the system and set it to backwash.

Installing a Salt-Free System:

1. The first step is to decide where you want to install it.
2. Then, you can close the home water supply, after which you completely drain the pipes in the house.
3. Cut the cold water supply pipe before the pre-filter housing.
4. Solder or glue the shut-off valve to the pipe. The technique you use differs according to the pipe material. Soldering is required for copper, while it is advised to use glue for PVC.
5. Now you can install the pre-filter.
6. Connect the downflow outlet to the cold water supply pipe.
7. Proceed to close the shut-off valves.
8. Finally, turn on the water supply and check for leaks by slowly opening the shut-off valves one by one.

Water Conditioner vs. Softener

As you research hard water remediation, you inevitably come across two terms – softening and conditioning, each describing a different type of system. However, what both systems have in common is the reduction of water hardness effects on the plumbing system and various household appliances.

How water softeners work

Through the utilization of ion exchange, the system pulls minerals from the water going through the pipes, flushing them out of the system and replacing them with sodium ions.

How water conditioners work

Typically, they pass the water over or through a magnetic field that causes ions to realign so that they repel each other, which in turn causes them to not stick to plumbing and fixtures.

Differences

• Water quality: Sure, softening systems are better at fixing the water hardness issue, but that’s pretty much all they’re good for. On the other hand, conditioners rid you of the problems related to scale on plumbing and fixtures and provide an added benefit as they help remove chlorine and other contaminants as well, leaving the water healthier for use and consumption.
• Efficiency: In regards to efficiency, softeners are superior as they directly tackle the issue as opposed to conditioners that simply reduce the effects had by hardness-causing minerals.
• Costs: Softeners use the ion exchange process that involves electricity that inevitably drives up operational costs, and as salt is required, you can expect to spend an estimated $200 per year on maintenance-related tasks. On the other hand, conditioners don’t use electricity in the process, don’t create wastewater, and don’t require any maintenance aside from routine filter changes.

Conclusion: If water hardness has reached worrying levels, we recommend a softener as it exclusively tackles issues with minerals that lurk in the water as opposed to conditioners that simply reduce the effects of hardness to prevent scaling.

Frequently Asked Questions

What exactly does a water softener do?

The most common type of softener is the ion exchange unit. What it does is remove minerals like calcium and magnesium from the water by trapping them in resin beads and exchanging them for sodium or potassium. At the end of the process, the chloride solution becomes a waste stream that is separately discharged down the drain.

Will a water softener clean the pipes?

The first signs of scale removal are noticeable within two weeks usually. With time, the soft water removes hardness and flushes it through taps and water-fed appliances. Complete removal of scale from the pipework is the inevitable outcome, but it does take a while – approximately 2 years on average. However, at the end of this estimated period, there won’t be a single issue with the pipe system in your home anymore.

How much does it cost to install a water softener?

There are a few variables that must be taken into consideration to figure out an estimated cost for the installation – the type of system you bought, how difficult the machine itself is to install, and the fees of the contractor. If you take up the installation yourself, costs can range from $0 to $400 depending on whether or not you have all the hardware you need, while with professional installation it can cost thousands of dollars.

Can I install it myself?

Yes, as long as you follow the instructions provided by the manufacturer or the ones given in the previous section of this article, you should be able to go through with the procedure on your own even if you’re not the handiest person out there. If you don’t trust your abilities at all, however, call in a professional. This way, you make sure that you will not damage the system in the process and void the warranty as a result.

How long do water softeners last?

The typical lifespan ranges from 10 to 15 years. However, it varies depending on a series of factors like system quality, maintenance, and usage. Components eventually break, and there are issues independent from you that could alter the system, so its lifespan is bound to end at one point.

How do I know what size water softener I need?

To estimate the size of the system, you must multiply the number of people in your household by 80 gallons. This is the average water use of a person throughout a single day, after which you multiply the resulting number by the grains of hardness your water tackles to establish the ideal amount of grain removal per day.

Is it better to drink hard or soft water?

The process of softening water takes away its minerals, which is problematic since one of the ways we get the daily mineral intake needed for our health is through hydration. However, considering the disastrous effects hard water has on plumbing and water-using appliances, it’s best to make some changes in your diet and get those minerals (calcium, magnesium, and others) from other sources. There is another issue related to soft water, namely that it can have a higher sodium content, which is contraindicated for people who suffer from certain health issues.

Does soft water cause hair loss?

No, this is nothing but a myth. Shampooing with hard water harms your hair. The high levels of minerals make it seem like your hair has more structure or volume, when in fact the hard water is making it look duller and causes breaking and splitting. On the other hand, soft water penetrates the shaft easier, giving your hair a soft and shiny look.

Is softened water bad for houseplants?

If the softening system you have installed amps the sodium levels in the water, it’s not advised to water your garden with the softened water. The sodium affects the plants and can even kill them because the plants will believe they have absorbed more water than they did, essentially dying of thirst in the end.

Conclusion

Even though water hardness isn’t as pressing of an issue as water contamination, it still needs to be solved. This is because there are consequences to ignoring it, more precisely the fact that fixtures and appliances deteriorate with time, and even your hair and skin can be affected by the irritation and dryness that ensue.
