Why Do You Need a Water Softener for Well Water?

The primary use of a water softener is to treat hard water. Compared to a municipal water system, well water is more likely to be hard.

Instead of coming from a dedicated reservoir, well water is taken from the ground, which tends to contain more hard minerals. The municipal systems are also regularly treated to remove minerals and impurities, whereas wells typically are not.

Wells draw water from a water table located deep beneath the earth. As water from nearby water sources and precipitation seeps into the ground, minerals found in the soil also work their way into the water table.

Hard water is not typically considered a major health risk. However, some health professionals believe that regular exposure to hard minerals may cause damage to organs and increase the risk of cardiovascular disease.

Skin irritation is another potential side effect of drinking hard water, especially for people who already suffer from a skin condition such as eczema. You may experience dry skin, bumpy patches, and irritation as a result of consuming hard water.

Hard water can also affect the health of your home. The buildup of calcium and magnesium deposits increases the risk of clogged pipes.

It can also make soaps and detergents less effective. When you have hard water, you may notice yellowish or brownish stains in your sinks and tubs. The hard water may even make it difficult to clean clothing and linens in your washing machine or to remove stains.

If you detect any of these issues, you may need a water softener for your well water.

How Does a Well Water Softener Work?

The typical well water softener is installed in your home’s plumbing system. It treats the water coming into the home from the well before sending the softened water to your bathrooms and kitchen.

These appliances rely on a process called ion exchange wherein they replace minerals with other minerals. In most cases, the water softener replaces hard minerals with sodium.

Most systems have two tanks – the mineral tank and the brine tank. The mineral tank is filled with resin beads that carry a negative charge. The hard minerals carry a positive charge. When the hard water flows into the mineral tank, the calcium and magnesium cling to the resin beads.

The system can then send softened water through the home’s water supply. A brine solution is then used during a regeneration cycle to wash away the magnesium and calcium.

The brine tank is filled with a brine solution, which typically includes common salt. When the water softener system is regenerating, it reverses the water flow and flushes dirt from the tank.

The brine solution containing sodium ions flows into the mineral tank and replaces the calcium and magnesium minerals that are attached to the resin beads. The hard minerals get flushed down the drain, the mineral tank gets flushed, and the brine tank gets refilled.

This process repeats itself to continue delivering soft water to your home. However, there are different types of water softeners featuring various settings and options. For example, some softeners allow you to set the frequency of the regeneration cycle.

When Should You Not Use a Water Softener for Well Water?

Depending on the mineral concentration of your water, a water softener for well water is sometimes not recommended. The trace minerals found in all water systems are beneficial to your health.

Calcium and magnesium are essential nutrients. However, excessive levels of hard minerals may lead to the disadvantages discussed, such as increased risk of cardiovascular disease and stains in your tubs and sinks.

If your water does not have high levels of hard minerals, a water softener is typically not necessary and may remove beneficial minerals from your water.

Testing Your Well Water Before Installing a Water Softener

Water testing in a lab

The best way to determine whether or not your well water contains high concentrations of hard minerals is to have your water tested at a professional water testing laboratory (select your state or territory here to find and contact a certified laboratory to test your drinking water).

In fact, many water treatment professionals recommend that you get your well water tested at least once per year.

Testing labs are available in most regions. You may also be able to find a water testing lab at your local university. Many agricultural departments offer water testing or can direct you to the nearest laboratory.

Another option is to contact a local water softener company. These companies occasionally offer free testing to encourage homeowners to purchase their equipment. Depending on the company, they may send you a home testing kit or request that you deliver a water sample.

You can also purchase home testing kits on your own. These kits include testing strips that you place in the water.

The strip contains chemicals that react to the presence of specific minerals. When these minerals are present, the testing strip changes color to indicate the hardness measurement.

Whether you use a home testing kit or send a water sample to a lab, you are primarily testing the hardness of the water.

The hardness is measured in grains per gallon (gpg) or parts per million (ppm). One gpg equals about 17.1 ppm. Typically, 60 to 120 ppm indicates moderately hard water. Levels above 120 ppm may lead to soap scum, stains, and potential health risks.

Besides testing the hardness of the water, these tests may help detect any other issues with your water as well. You can test for the presence of lead, chlorine, and pesticides. You can even check the pH level of your well water.

Bacteria is another contaminant that you may want to test for in your well water. High concentrations of magnesium and calcium make it easy for bacteria to grow and travel through your water system.

If a water test confirms that you have hard water, your best option is to install a water softener system.


The Best Water Softeners for Well Water (2020 Reviews)

Choosing the right water softener system for your home depends on the amount of water your household uses. Most softener systems include a maximum flow rate and grain capacity.

The maximum flow rate refers to the flow rate of your water system. Most residential systems have a flow rate of 6 to 12 gallons per minute.

The grain capacity refers to the total number of grains of hardness that the system can remove before needing to complete the regeneration cycle. You may find systems with grain capacities ranging from several thousand to tens of thousands of grains.

To determine your needs, estimate your water usage. The average person uses about 80 gallons of water per day. With a four-person household, you may use 320 gallons per day.

After testing your water, you should know the hardness rating in grains per gallon (gpg). Multiply your daily household water usage by the total grains to determine the grain capacity that you need.

For example, a household using 320 gallons per day and 10 grains per gallon of hardness will need a water softener system with at least a 3,200-grain capacity.

There are many other features to consider, including digital controls, regeneration time, and additional filtration. To help simplify your search, here is a roundup of the seven best water softeners for well water in 2020.

Besides going through the softening process, the water must pass through a pre-filter and a UV filter. The UV filter helps to kill bacteria while the pre-filter catches sediment and minerals.

One advantage of the Aquasana Softener is the lack of salt. Some homeowners do not want to use salt to remove hard minerals from their water. There is some concern about the potential health risks of adding sodium to the water, even if most of the sodium gets washed away during the regeneration cycle.

One of its drawbacks is the flow rate. This appliance is rated for use in households with a maximum flow rate of 7 gallons per minute. Some households have flow rates up to 12 or 14 gallons per minute, which would make this system ineffective for treating well water. However, if your home has a low flow rate, this system offers advanced filtration.

Due to the filtration components, there are additional tanks to install. Some users may experience trouble getting it set up properly. Luckily, the instructions help explain the installation process with step by step details.

In the end, the Aquasana Softener and Filtration System is an efficient appliance. After you get it installed, you can relax knowing that you have clean water traveling through your pipes. However, not everyone needs the advanced filtration features.


  • It is salt-free.
  • You can remove harmful contaminants and deliver pure water to your kitchen and bathrooms.
  • You can also remove chlorine and chloramines with this system.


  • Ineffective for use in households with a flow rate of up to 12 or 14 gallons/minute.
  • Another issue is the installation process. While installation is relatively straight-forward, the Aquasana system includes more components compared to a standard water softener.
  • Some users may face trouble getting it set up properly due to the additional tanks. Professional help might be needed.

Who should consider using the Aquasana Softener?

If you simply want to eliminate hard water, this softener system is overkill. For those that want to get rid of lead and harmful pollutants, it is one of the most effective options.

5. AFW Filters Iron Pro 3 48K Softener

The AFW Filters Iron Pro 3 Softener uses a metered digital control head so that the appliance only begins the regeneration process when necessary. This helps to reduce water waste and energy, saving you money compared to a time-based regeneration system. With the 12 gallons per minute flow rate, the system should not reduce your water pressure.

If your water contains a lot of sulfur, the filter will likely need to be replaced more frequently.


  • It is energy-saving thanks to its metered digital control head.
  • It should work for most households unless your home has a high flow rate.
  • It removes iron and sulfur.
  • It is affordable.


  • It does not come pre-loaded with filter media. You will need to purchase a KDF85 resin filter media.

Who should consider getting the AFW Filters Water Softener?

This system is best suited for medium to large households that need to soften water and eliminate lead. It is also a great choice if you need to get rid of sulfur from your well water. Just remember that you may need to replace the filter frequently.

6. Triple Action Poly Salt-Free Water Softener

If you do not like the idea of using salt to remove hard minerals from your water, you should examine the features of the Triple Action Poly Salt-Free Water Softener.

It features a unique design with a single tank that easily connects to your existing plumbing. Other details include the following:

  • Has a maximum flow rate of 30 gallons per minute
  • Features a 140 psi maximum pressure rating

This unit is also called the Hard Water Bullet, which is a fitting name when you look at the design of the softener system. It is a compact filtration system that offers triple action softening and filtration.

It includes a stainless steel filter to help remove contaminants. After the water passes through the stainless steel filter, it reaches the main component, which includes an electro-mechanical process to condition the water. It breaks down the calcium into aragonite crystals.

Aragonite is a softer type of calcium and does not cause the same hard water problems. It does not clog up your drains or cause stains. However, it does help coat the inside of your pipes and provides a protective layer against corrosion.

The third part of the filtration and softening process includes polyphosphate crystals. These crystals keep the iron and aragonite from entering traveling to your kitchen and bathroom plumbing fixtures.

There are several reasons to consider getting the Triple Action Poly Salt Free Water Softener instead of one of the other options. First, it is one of the easiest water softeners to install.

The unit can be placed almost anywhere. In fact, you can even install it outdoors. It is built for rugged use and can withstand both cold and hot temperatures.

The Hard Water Bullet is also compact. It measures just 4.5 x 4.5 x 10 inches, while many water-softener tanks measure 45 x 10 inches. Its compact lightweight design makes it easy to install.

As the softening process does not require backwashing, there is no wasted water. You also do not waste brine water, as the system does not use a brine solution.

While the ease of installation is a great reason to consider buying this water softener, there are other advantages as well. With this system, you may never need to replace the filter. The stainless steel filter may need occasional cleaning; however, it is designed to last for a lifetime.

This appliance is also suitable for use in residential properties with a lot of occupants. The 30 gallons per minute maximum flow rate ensures that you do not experience any changes to your water pressure.

You also get everything that is needed to install the unit, including a mounting wall bracket, polyphosphate cartridge, and instructions.

While this is a great appliance, there is one issue that may deter some homeowners from using this water softener. The Hard Water Bullet does not eliminate calcium and magnesium.

Instead of eliminating the hard minerals, the appliance breaks the minerals down. The calcium becomes aragonite. This aragonite can protect your plumbing. However, some people find that the water still tastes like hard water.


  • It is vert easy to install.
  • It can withstand both cold and hot temperatures.
  • It is not space-occupying.
  • The system is built such that you may never need to replace it.
  • It is good for households with a large flow rate (up to 30 gallons per minute.)

Who should buy the Triple Action Poly Salt-Free Water Softener?

The top reason to consider buying this appliance is its compact design. You should not have any problem finding a spot for this water softener, whether you choose to install it indoors or outdoors.

With the provided mounting bracket, you can mount it on a wall, instead of needing to find a spot on the ground to set a large tank.

The twin tank water softener offers greater grain capacity compared to the other options. Each tank has a 40,000-grain capacity, providing a total capacity of 80,000 grains and reducing the need to frequently complete the regeneration cycle. This saves you energy and ensures that you always have fresh, soft water.

The softener system comes equipped with the filtration media inside the fiberglass tank, making installation a fairly easy. The installation process itself is already simple. You can quickly connect the tanks to your existing plumbing and start softening your well water within a couple of hours.
