For those interested in removing water hardness from the entire home with a traditional ion-exchange system, and don’t already have a filter which reduces particles from their well source, this may be the right fit.

Aquasana is a manufacturing company based out of Austin, TX and specializes in innovative filtering technology.

The well water Rhino is a whole-house water filter and UV purifier with the option of adding a salt-free water conditioner for reducing hardness.

The sediment pre-filter catches large particles of silt and rust before entering the SCM salt-free conditioner. Scale Control Media (SCM) uses water flow to naturally alter the structure of hard mineral ions into a crystal structure that prevents the minerals from binding and forming scale buildup.

Unlike salt-based softeners, Aquasana's Salt-Free Water Conditioner will not demineralize your water, harm your pipes with harsh salt, or put excessive amounts of sodium waste into our communal water supply.

The activated carbon filter reduces herbicides and pesticides while alkalizing the water with healthy minerals. Finally, the UV purifier eliminates any bacteria or viruses that may lurk in the water supply.

The water conditioner, UV purifier, and carbon filter make this an ideal filter for homes on well water supply.

For those who have a water hardness problem from their well supply, but would rather not house a salt-brine tank, this salt-free water softener will remove hardness very effectively in addition to purifying it from harmful contaminants.

The “hardness” or “softness” of a water supply simply refers to the presence of dissolved minerals in the water.

Water with a higher concentration of dissolved particles is considered hard, while a lower concentration is considered soft.

The criteria for determining water hardness might differ from region to region based on measuring standards, the types of elements present, and testing specifications.

But in general, hard water can always be associated with a higher concentration of dissolved minerals.

Hard Water Faucet

Effects of Hard Water

A variety of elements may be present in order to determine hardness, including iron, aluminum, and manganese, but the two most prevalent elements are calcium and magnesium.

The presence of calcium and magnesium isn’t harmful to the human body if ingested but can, in fact, be beneficial in moderate amounts.

However, calcium and magnesium can cause limescale buildup in pipes and faucets and ultimately clog up the plumbing system over time.

If left untreated, the damage that hard water can cause to a water system can certainly be costly.

Causes of Hardness of Water

Calcium and Magnesium are particularly prevalent in well water systems. As groundwater flows through porous rock, minerals are gradually collected and introduced into the water supply.

Iron, evidenced by the orange-red tint it leaves in faucets and bathtubs, is another troublesome element that is often present in well-water systems.

While iron in low concentrations may be efficiently removed through the softening process, higher concentrations of iron may require additional treatment methods, which will be discussed in this article.

Nevertheless, calcium, magnesium, low concentrations of iron, and any other mineral present in the groundwater supply may be treated by incorporating a water softener into the well system.

Prolonged Life of Plumbing System

Perhaps the most damaging effect of hard water is the limescale build-up it can cause inside water pipes and fixtures. Prolonged exposure to magnesium and calcium-rich water can cause limescale buildup, which can prevent adequate water flow and also cause corrosion.

Water softeners can significantly prolong the life of a home’s plumbing system simply by reducing the damaging effects of limescale buildup.

In addition to the plumbing system, household appliances and fixtures are significantly affected by hard water, as seen by scale buildup in coffee makers, sink fixtures, and bathtubs.

Water softeners can eliminate unsightly and troublesome buildup on home fixtures.

Lowered Energy Bill

Most appliances work more efficiently when using soft water as opposed to hard water due to the scale buildup, which can prevent the proper flow of water.

Water heaters, in particular, can perform significantly better with soft water due to less strain on the system that hard water build-up can cause.

The Water Quality Research Foundation performed a study that revealed that water heaters can save up to 27% on energy costs in a single when used with a water softener.

Reduce Soap Usage and Improve Skin Health

Hard water negatively affects the soap-lathering process as the ions make it harder for soap molecules to form bubbles. Soft water creates soap to lather much easier and is much less harsh on the skin.

Hard water also leaves magnesium and calcium build-up on the skin, which can cause itchiness and irritation.

Keep Fabrics Soft, Colorful, and Fresh

Minerals from hard water can damage clothing, leaving them feeling stiff and reducing the vibrance of the colors. Water softeners can have a significant improvement on laundry.

The two most common units of measurement for water hardness in the US are parts per million (ppm) and grains per gallon (gpg).

PPM

The term, parts per million, is defined as having 1 milligram of dissolved minerals for every Liter of water. For example, a Liter of water which measures as 1 ppm, contains 1 mg of dissolved minerals within it.

GPG

The term grains per gallon is defined as having 1 grain (which is equivalent to about 64.8 mg) of dissolved minerals for every gallon of water.

There are several other units of measurement used for testing water hardness, but in the United States, ppm and gpm are most commonly used. While the different units of measurement can often become confusing in determining water hardness, each unit can be converted to suit measurement needs.

1 PPM = 0.05842 gpg

1 GPG = 17.2 ppm

Hardness Map / USGS

The US Geological Survey categorizes water hardness into different levels of concentration, as explained by the following chart. While there are many other factors involved which ultimately determine hardness, the four categories of soft, moderately hard, hard, and very hard are precise enough for practical purposes.

Water that is less than 60 ppm or 3.5 gpm is generally considered soft in most cases and should be the target range for those with concern about the negative effects that hard water can bring.

USGS Water Hardness Map

Water can be tested by using test strips which are dipped into a glass of water. As the color on the test strip changes, it can be matched with the provided color chart to determine the level of hardness.

Hardness can also roughly be determined by dispensing drops of liquid soap into a glass of water. As a general rule of thumb, the more drops of soap required to produce soap suds, the harder the water is.

Water softeners work by treating magnesium, calcium, and iron-saturated water through a process called ion exchange. Ion exchange works by replacing these unwanted elements with more desirable elements, such as sodium. The entire water softening system, comprised of a brine tank, resin tank, and control valve, can be better understood by explaining the function of each of these components.

Prefilter

In addition to the calcium and magnesium, which groundwater is naturally saturated with due to the porous rock which it flows through, particles of sand and debris are commonly found in well water systems. Because small particles can potentially damage and clog a home plumbing system, it is reasonable to attach a pre-filter before the water reaches the softening system.

A pre-filter blocks larger particles such as sand, rock, and debris from entering the resin tank and causing further complications to the system.

Resin Tank

The resin tank houses the ion exchange resin – tiny beads which conduct the ion exchange process and are pre-charged with sodium ions. As hard water flows through the resin tank, the magnesium and calcium ions come into contact with the resin beads and attach to them, ejecting the sodium ions and releasing them into the water.

The water is now sodium-rich and magnesium and calcium-free. Sodium is a much more preferential element to have in the water as it is less damaging to home plumbing than iron, calcium, and magnesium can be.

Brine Tank

The brine tank houses the sodium pellets from which the sodium ions are generated. At regularly scheduled intervals, sodium-rich water from the brine tank is flushed into the resin tank to redistribute sodium ions back to the resin beads and to “clean” them of the hard ions.

The magnesium, calcium, and iron ions that were collected from the hard water can now be flushed out of the resin tank, leaving the resin beads fresh and ready for the next exchange.

Control Valve

These ion-exchange cycles can be controlled electronically through the control valve, which dictates the cycling schedules.

Throughout the week, and depending on how much water is used, the water softener system will go through several of these exchange cycles – with hard water first entering the resin tank, being released into the home as soft water, and then “regenerating” the resin tank with sodium-rich water from the brine tank.

Post Filtration

Using a water softener for non-consumption purposes such as showering, washing dishes, and doing laundry can be used as-is and won't necessarily require an additional filter. But water intended for drinking will require an additional filter to make it safe for consumption and to reduce the salty flavor.

Because the main function of a water softener is solely to remove hard minerals by replacing them with salt, it doesn't address microorganisms, chlorine levels, and other potential contaminants.

An additional under-sink reverse osmosis system, UV filter, or post-carbon filter will make the water safer and better-tasting for consumption. Find out more about these home reverse osmosis systems and ultraviolet disinfection systems that integrate well with water softeners.

It is not uncommon for well systems to contain magnesium, calcium, manganese, and iron. While these minerals can be effectively treated with a water softener, higher levels of iron may need an iron filter in addition to the water softener.

How to Set up a Water Softener with a Well Pump

Because well pump systems rely on an accurate reading of water pressure in order to properly pump and distribute water to the house, there shouldn’t be any interference between the pump and the pressure tank. The water softener system should therefore be placed AFTER the water flows from the pressure tank and BEFORE it is ready to be distributed to the house.

Typically, the step-up should be in this order:

1. Well Pump
2. Pressure Switch
3. Pressure Tank
4. Pre-filter (optional)
5. Resin Tank
6. Iron Filter (optional)
7. Fine Carbon Filter (optional)

For well systems with high sediment content, optional sand filters can be placed before and after the water softener to reduce debris.

How to Treat the Iron Problem

As mentioned before, small amounts of iron will be treated in the resin tank along with calcium and magnesium, producing soft water for the household.

Regions with iron concentrations of 1 ppm or less may not need additional treatment and can rely on the water softener to treat all of the minerals in the water. There are some regions, however, where iron concentration can reach 10 – 15 ppm or more and may need the help of an iron filter.

There are three main types of iron issues that homeowners may experience: ferric iron, ferrous iron, and iron bacteria. Ferric iron, also known as “red water iron”, are insoluble iron particles that are visible to the naked eye and can be easily filtered through the proper media.

Ferrous iron, also known as “clear water iron”, is dissolved into the water and is invisible to the naked eye. Iron bacteria, on the other hand, aren’t iron particles at all but tiny microorganism which feeds on iron and can be evidenced by the red slimy residue which remains in toilet tanks and pipes.

How Iron Filters Work

Dissolved, ferrous iron in low concentrations (1 ppm) can be softened with a standard water softener. Ferric iron, iron bacteria, and higher concentrations of ferrous iron will need an iron filter or a water softener with an iron filter built into it.

Iron filters, which look very similar to water softener tanks, work by filtering out the different forms of iron through the necessary media filters. Most iron filters will contain the media required to treat all three types of iron issues and can be incorporated into a water softener system.

The most cost-effective and space-efficient way to solve an iron problem is to purchase a water softener that includes an iron filter. Many water softener manufacturers have built-in iron filters, which eliminate the need for an additional tank. Read our article on the best ways to remove iron from a well water source.

Proper maintenance of a water softener can prolong its life and save time and money on repairs. These are some of the best maintenance and troubleshooting tips for ensuring a well-managed system.

Maintain the Brine Tank

To ensure that the brine tank is in good order, be sure to check the salt levels once per month. As a general rule, the brine tank should be at least half-full with salt and about 3 inches above the water level. Salt bridges, or layers of hardened salt within the brine tank, can form over time and need to be periodically broken to ensure proper water flow. They can be broken up by pouring hot water to dissolve them and stirring it with a clean stick.

Clean the Brine Tank

While older water softener models can benefit from an annual cleaning, newer models can endure 5-10 years without the need for cleaning if proper maintenance has been kept. Brine tank cleaning may be required if the softener has lost the ability to remove hardness and if troubleshooting methods have failed.

1. To clean the tank, use the bypass valve to shut off water intake and dump the entire contents of the brine tank, salt, and water together.
   
   
2. Wash the entire inside of the tank with a generous amount of soap and water. Use a hose to thoroughly rinse.
   
   
3. Pour a ¼ cup of bleach and 2-3 gallons of water into the tank and let sit for 15 minutes.
   
   
4. Rinse the tank once more and refill it with salt. Wait a few hours before restarting the tank so the salt can dissolve.

Use Proper Salt

Each water softener will have its preferred type of salt to use in the brine tank and can be referenced in the manual. Only the manufacturer’s recommended type of salt should be used. While rock salt is less expensive, it also contains impurities which may decrease the efficiency of the system. Evaporated salt is the purest form available.

Cleaning Iron-fouled Resin Beads

For water softener systems without an iron filter, high deposits of iron can eventually cause the resin beads to have too much iron deposits and may require cleaning. In order to clean iron-fouled resin, iron removal solutions such as Iron Out or Rust Out. To clean iron-fouled resin beads, pour the cleaning solution into the brine tank and regenerate the resin tank as normal. Heavily fouled resin tanks may require several cycles.

Each water softener will have its own grain capacity, a measurement of how much ion-exchanging the resin tank can perform before needing to be regenerated with sodium. An improperly sized water softener can result in too much water and salt usage and/or oversaturation of the resin beads.

In order to avoid excessive water and salt usage, a water softener should ideally regenerate no sooner than every three days. And in order to preserve the life of the resin, it should regenerate no longer than 14 days in between cycles. On average, a 7-day regeneration cycle is ideal for most households.

In order to calculate the required grain capacity for a household, one would need to know the amount of water used per day measured in gallons and the amount of hardness measured in grains per gallon (GPG).

1. Determine Water Hardness - For those using city water, hardness is usually made public in online annual reports. Well owners can test their water with a test kit to determine hardness. Hardness should be measured in GPG and can be converted from mg/L by dividing by 17.1.
   
   
2. Determine Daily Water Usage - In order to get a rough estimate of the amount of water used per day, count the number of people who live in the household and multiply it by the average number of gallons used per day, which is 70 in the US. For example, a household with four people uses about 280 gallons of water per day (4 x 70= 280).
   
   
3. Calculate Daily Softening Requirement - To calculate the daily softening requirement, multiply the water hardness in GPG by the total amount of daily water usage in gallons. For example, a water hardness of 10 GPG multiplied by a daily water usage of 280 gallons equals 2,800 grains. The water softener will need to regenerate 2,800 grains per day.
   
   
4. Select a Water Softener with the Appropriate Grain Capacity - Because the target regeneration frequency for water softeners should be every seven days, selecting one with the correct grain capacity is important. If the required daily softening requirement for our example is 2,800 grains per day, we'll need to multiply that by seven days, which is 19,600. The water softener required should have a grain capacity of about 19,600.

Most water softeners are sold at 24,000, 32,000, and 48,000-grain capacities. In most cases, rounding up to the nearest grain capacity would be efficient. For our example, the water softener with the 24,000-grain capacity would suit the 19,600-grain capacity requirement.

Can You Mix Different Types of Salt in The Water Softener?

Mixing different types of salt together in the salt tank isn’t necessarily harmful, but it may complicate the softening process and potentially damage the water softener system. Each water softener system is designed to use a specific type of salt and should only be used with what is recommended by the manufacturer.

Substituting a different type of salt may not allow the system to function properly. If a particular system allows for more than one type of salt at a time, it is best practice to drain the unit of one type of salt before adding the other.

How Much Sodium is Ingested from Softened Water?

The amount of sodium ingested from a water softener unit largely depends on the hardness of the water, but on average, less than 3% sodium uptake comes from ingesting softened water. This estimates to about two teaspoons of table salt per day, which is very minimal in comparison to the daily amount of sodium that should be ingested from foods.

Do Water Softeners Make Water Safe to Drink?

Water softeners do not purify water of contaminants and, therefore, should not be relied on to make water safe for drinking. Water softeners merely reduce the number of minerals in the water, not harmful bacteria or viruses. A purification device such as a fine carbon filter or UV filter will make the water safe from contaminants.

When do the Resin Beads Need to Be Changed?

If a water softening unit is maintained properly, it may not need to have the resin beads replaced in its lifetime.

Why Does Soft Water Feel Slick and Smooth When Taking a Shower?

Hard water, which is high in calcium and magnesium, greatly affects the lathering ability of soap and prevents it from dissolving properly in water. This interaction makes soap scum adhere to surfaces more easily, including clothes, dishes, and skin. Soft water allows soap to slide off the skin more easily, as it is designed to do. This may make showering feel smoother.

Hard water is a term that many might not have a full understanding of, but as we've discovered, water hardness isn't a health concern in terms of consumption. The danger of hard water is mostly related to the calcification of plumbing and household fixtures. Iron, an element that is often present in most well systems, can present its own set of problems. While low concentrations of iron can be remedied with most water softening systems, higher concentrations will need an iron filter.

It is important to properly size the water softener according to the level of hardness and the daily amount of water being used in the household.
