If you’re among the 85 percent of the US population with hard water, it’s time to consider a water softener system. Hard water can cause costly damage to your home, appliances, and plumbing. It can also make bathing and cleaning more difficult, as well as leave behind unpleasant residues. Luckily, there are many effective water softener systems on the market that can help mitigate these issues.
We’ve done the research to determine which systems are the best and most effective for your needs. We considered ease of installation, salt consumption, operating costs, maintenance requirements, and warranties. Also, we made sure each product offers a variety of features that can be tailored to individual household needs.
Salt-based water softeners are the most popular choice for homeowners due to their effectiveness. These systems work by passing hard water through a resin bed which is charged with sodium ions. The hardness minerals are attracted to the sodium ions and become trapped in the resin bed. The sodium-charged resin bed then releases sodium-rich softened water into the home water line.
In contrast, magnetic water softeners don’t exchange ions. Instead, they use a strong magnetic field to weaken the bonds between the hard ions which prevents them from sticking to the pipes or other surfaces. Magnetic water softeners are not as effective as salt-based ones.

When shopping for a water softening treatment, there are several key factors to consider to ensure the unit meets your needs.
If your water is very hard, then a salt-based softening system may be best for you. On the other hand, if you are looking to avoid limescale buildup in pipes but keep the mineral-rich taste, then a salt-free descaler may be more suitable for you.
The first step in determining the required grain capacity for your home is to check your water hardness. Hardness is measured in grains per gallon (GPG) and is the measure of the number of minerals that are dissolved in the water. The higher the GPG, the harder the water, and the more minerals it contains.
Water that is between 1 and 3.5 GPG is considered slightly hard, while water that is between 7 and 10.5 GPG is considered hard water. You can find out the hardness of your water by having it tested by a professional or purchasing an at-home test kit.
Once you know the hardness of your water, you can use that information to calculate the grain capacity of the water softener you need. The average person uses approximately 80 gallons of water per day, so for a family of five, that translates to 400 gallons of water per day. So, if your water hardness is 7 GPG, you can use the following calculation to get an idea of the grain capacity your water softener should have to treat hard water for at least a week (7 days).
7(GPG) x 400 (daily water usage) x 7 (days) = 19,600 (Grain Capacity)
Using these calculations, a family of five would need a water softener with at least 19,600 grains capacity.
Installation can range from simple DIY projects where all materials and instructions are provided, to full-service installations that require professional contractors. If a professional installation is required, inquire about the initial cost and manage your budget accordingly.
Regular maintenance is also essential for keeping your water-softening system running efficiently. A good rule of thumb is to check the performance of your unit every 3-4 months by testing for hardness levels in your water supply. Also, make sure that you replace any necessary filters according to manufacturer specifications for optimal performance levels and extended product life.
Installing a basic water softener can cost anywhere from $150-$600, depending on if it is an electric or non-electric model and other features. Higher-end systems typically include larger tanks that are designed for large households or commercial use and can cost $1000 or more to install.
The installation of a water softener requires basic plumbing abilities and knowledge of electricity and wiring. If you do not have any expertise in these areas, it would be best to hire a professional plumber instead of trying to tackle the job yourself.
However, the job is much easier if you’re just replacing an old unit since all of the plumbing connections will be in place. If you’re starting from scratch, you’ll have to put all of the pieces together.
The average lifespan of a water softener is typically estimated between 10-20 years, depending on the brand and model. The expected longevity of a water softening system is greatly dependent upon the level of usage, maintenance, and proper installation. Regularly checking and replacing brine tank components such as salt grids, resin beds, and other hardware components can extend the life expectancy of a water softener.
A standard-sized bag of water softener salt can be expected to last between 6 to 8 weeks. Although this can vary depending on factors such as the hardness of the existing water supply and how frequently the softener system is used.
If a water softener is not replenished with salt, the system will become saturated with calcium and magnesium ions from hard water. This saturation can reduce its efficiency in softening the water by causing the precipitation of insoluble salts. Moreover, cations present in the hard water may become concentrated, leading to the formation of scale buildup on surfaces that come into contact with the softened water. Such scale buildup can act as a barrier to ion exchange leading to further reductions in softening efficiency.
Evaporated salt is the preferred choice for use in a water softener due to its hygroscopic properties. Its ability to absorb moisture allows it to dissolve more quickly and evenly than other salts, thus providing higher efficacy in the softening process.
