How to Choose Water Softener: A Simple Guide

How to Choose Water Softener

Water softeners are essential for any household that struggles with hard water. Hard water is caused by the presence of minerals like calcium and magnesium, which can lead to several problems, such as limescale buildup, reduced soap lather, and damage to appliances. A water softener can alleviate these issues by removing or reducing these minerals, providing smoother, cleaner water for your home.

Choosing the right water softener for your household can be daunting, but it can greatly improve your quality of life. To get started, it’s important to determine the size of the water softener you need based on your family’s water consumption. The average person uses 80 to 100 gallons of water per day, so consider this when calculating the size needed for your system.

When selecting a water softener, keep your household size and specific needs in mind, as well as the grain capacity requirements. Systems typically range from 20,000 grain capacity for smaller households to 64,000 grain capacity for larger households. By making an informed decision, you’ll be well on your way to enjoying the benefits of softened water.

Understanding Hard Water

How to Choose Water Softener

Hard water contains high levels of minerals, specifically calcium and magnesium. These minerals can affect the functionality and lifespan of household appliances and plumbing systems.

Common Minerals in Hard Water

  • Calcium: Calcium is one of the most common minerals found in hard water. It’s responsible for white deposits that can be seen on faucets, showerheads, and appliances.
  • Magnesium: Another common mineral found in hard water, magnesium can also cause buildup on fixtures and appliances, reducing their efficiency and life expectancy.

Signs of Hard Water

Some common signs that you have hard water in your home include:

  • White or chalky deposits on fixtures, dishes, and appliances
  • Soap scum buildup in sinks, bathtubs, and showers
  • Reduced water flow in pipes and appliances
  • Dry, itchy skin and dull hair after showering
  • Spots on glassware after washing
  • Reduced effectiveness of detergents and soaps

Water Hardness Levels

Knowing the hardness level of your water is essential for choosing the right water softener. You can determine the hardness of your water by using a hard water test kit or looking up water reports from your municipal provider. Water hardness is measured in grains per gallon (GPG).

Here’s a general guideline for understanding water hardness levels:

Water Hardness LevelGrains per Gallon (GPG)
Soft0 – 3.5
Moderately Hard3.5 – 7.0
Hard7.0 – 10.5
Very Hard10.5+

Having a good understanding of your water’s hardness level will help you choose the correct size of water softener to effectively treat your home’s water.

Types of Water Softeners

There are various types of water softeners that can help tackle different hardness levels and needs. This section provides a brief overview of the main types available and their features.

Salt-Based Water Softeners

Salt-based water softeners, also known as ion exchange systems, work by replacing hard minerals (calcium and magnesium) with sodium ions. The process takes place in a resin bed, which traps the hard minerals and releases sodium ions. The system needs to be regenerated regularly using water softener salt and water. Some key points about salt-based water softeners include:

  • Effective for removing hard minerals from water
  • Requires regular maintenance (adding salt and regenerating)
  • Increases sodium levels in treated water

Salt-Free Water Softeners

Salt-free water softeners, sometimes known as salt-free water conditioners, do not use salt to remove hardness. Instead, they rely on a process called template-assisted crystallization (TAC) that converts hard minerals into harmless crystals. Here are some highlights of salt-free water softeners:

  • Uses no salt or chemicals, which is environmentally friendly
  • Requires less maintenance compared to salt-based systems
  • Does not increase sodium levels in the treated water
  • May not be as effective for very hard water

Dual-Tank Water Softeners

Dual-tank water softeners are a specialized type of salt-based water softeners. They have two resin tanks, allowing one to be in use while the other is regenerating. This means you have a continuous supply of softened water, even during regeneration periods. Here’s what you should know about dual-tank water softeners:

  • Provides uninterrupted softened water supply
  • Can be more expensive than single-tank systems
  • Requires enough space for two tanks
  • Suitable for larger households or higher water usage

Magnetic Water Softeners

Magnetic water softeners, also known as electronic or magnetic descalers, are an alternative to traditional water softening systems. They use magnetic or electronic fields to alter the structure of hard minerals. This change reduces the minerals’ ability to form scale but does not remove them from the water. Below are some main points about magnetic water softeners:

  • Requires little to no maintenance
  • Easy to install, often just clamping onto pipes
  • Does not change or remove hard minerals from water
  • Effectiveness may vary depending on water hardness level and the specific device used

By understanding the different types of water softeners and their strengths and weaknesses, you can make an informed decision on the best option for your specific needs.

Selecting the Right Size

Choosing the right size water softener is essential for efficient water use and reducing excessive wear on the system. The size of a water softener is usually determined by its grain capacity, which is the amount of hardness that the softener can remove.

To select the appropriate size, you’ll need to consider your household’s water usage and the hardness of your water. Start by determining your daily water usage based on the number of people in your home and average water use per person. The average person uses about 80 gallons of water per day, but this can vary depending on lifestyle factors, home size, and other factors.

Next, test your water hardness to determine the grains of hardness in your water. Water hardness is typically measured in parts per million (ppm) and can be categorized as follows:

  • Soft: 10-50 ppm
  • Slightly Hard: 50-100 ppm
  • Hard: 100-200 ppm
  • Very Hard: 200 ppm and above

Once you have this information, you can calculate the necessary grain capacity for your water softener. To do this, multiply your household’s daily water usage by the grains of hardness in your water to figure out how many grains need to be removed each day.

Most common water softener sizes are:

  • 24,000 grains
  • 32,000 grains
  • 48,000 grains
  • 64,000 grains

A 64,000-grain softener is typically suitable for commercial use, but large households with high water consumption might also require such a size.

To help you decide on the appropriate size, use the following table as a guideline:

Water Usage (Gallons per Day)Grains of HardnessRecommended Water Softener Size
Up to 2,400Soft – Hard24,000 grains
2,400 – 3,200Soft – Hard32,000 grains
3,200 – 4,800Soft – Hard48,000 grains
Over 4,800Soft – Hard64,000 grains

Remember that these are general guidelines, and specific needs may vary depending on the home and water conditions. It’s always best to consult a professional or use a water softener calculator to ensure that you’re selecting the most suitable size for your unique situation.

Evaluating Water Softener Features

Regeneration Options

Water softeners use a process called regeneration to restore their softening capacity. There are three main types of regeneration systems:

  1. Metered System: This is a demand-based system that regenerates based on your water usage. The softener tracks the amount of water you use and regenerates when it reaches a certain threshold. This is the most efficient type of system as it only regenerates when necessary.
  2. Timed System: This type of system regenerates at fixed intervals, like every 2 or 3 days, regardless of the water usage. While it’s easier to maintain, this approach can lead to wasted water and salt if you haven’t used as much water as anticipated.
  3. Manual System: You need to manually initiate the regeneration process in this type of system. It’s the least convenient option but can be a cost-effective solution if you have low water usage and don’t mind putting in the extra work.

Control Heads

The control head manages the water softener’s operation, ensuring proper regeneration and overall functionality. There are two primary types of control heads:

  • Mechanical Control Head: This is a simpler and more affordable option that uses analog controls, such as dials or switches, for manual adjustments.
  • Digital Control Head: Equipped with an electronic interface, digital control heads offer increased functionality, such as customizable settings and easy-to-read displays. They generally provide better efficiency and ease of use but come at a higher cost.


Consider the following factors when evaluating a water softener’s efficiency:

  • Grain Capacity: This refers to the amount of water a softener can treat before needing regeneration, measured in grains. Larger capacities generally lead to increased efficiency, but it’s important to choose a size that aligns with your household’s water usage.
  • Salt Efficiency: The efficiency of salt usage depends on the type of regeneration system, with metered systems typically providing the best results. Look for models that use minimal salt to achieve desired softening effects.
  • Water Consumption: Some water softeners consume more water during regeneration than others. Opt for models that use less water, both for environmental friendliness and cost savings.

When choosing a water softener, carefully evaluate the regeneration options, control heads, and efficiency factors to find a model that best suits your household’s needs. Remember to consider your water usage, hardness levels, and budget, as well as the size and location of available space for installation, while making your decision.

Impact on Water Quality

Impact on Drinking Water

Soft water offers several benefits when it comes to drinking water quality. First, it typically tastes better because it does not contain excessive minerals like calcium and magnesium, which can cause hard water taste. However, the softening process involves exchanging these minerals with sodium ions. While this improves the taste, it can also increase the sodium content of the water. If you’re on a low-sodium diet, you might consider using an alternative filtration system, such as a reverse osmosis system, which can remove sodium from softened water.

Impact on Household Appliances

Soft water is known to increase the lifespan and energy efficiency of household appliances. Hard water can lead to deposits and buildup on appliances like water heaters, dishwashers, and washing machines. On the other hand, soft water helps in:

  • Preventing limescale buildup in pipes and appliances
  • Reducing detergent and soap usage as soft water lathers better
  • Prolonging the lifespan of appliances, leading to lower replacement costs

Soft water is more energy-efficient as there’s no mineral buildup in appliances, allowing them to run at optimal performance. Overall, this results in energy and cost savings in the long run.

Environmental Considerations

When choosing a water softener, environmental considerations should also be taken into account. Some water softeners use large amounts of salt, which can have negative environmental effects when discharged into wastewater systems. Excess sodium can harm aquatic life and contribute to soil degradation.

To mitigate this, you can:

  • Opt for a salt-free water softener
  • Regularly maintain your water softener to minimize salt usage
  • Use a reverse osmosis system to reduce the amount of sodium in your drinking water

By taking these factors into consideration, you can make an informed decision when choosing a water softener that will positively impact your water quality and minimize any potential harm to the environment.

Wrapping Up Your Decision

When it comes to choosing a water softener, budget considerations should play an important role. By knowing your financial limits, you will be better equipped to find the system that fits your needs without breaking the bank. Also, remember that prices can vary, so be sure to shop around for the best deals.

Another essential aspect to help you make an informed decision is reading reviews and comments from previous buyers. People’s experiences can provide valuable insights into the effectiveness, reliability, and user-friendliness of various water softeners. Just make sure to consider both positive and negative feedback.

Understanding your household’s water consumption is another key factor in selecting the right water softener. To determine your family’s water usage, consider how many faucets, sinks, and shower heads will be benefiting from the softened water. Remember, environmental factors and personal habits can affect your water consumption.

Now, as you narrow down your options, keep an eye out for models that function as descalers. Descalers can help prevent mineral buildup in pipes and appliances, ultimately prolonging their lifespans and enhancing the overall efficiency of your plumbing system.

Lastly, when choosing a water softening system, look for a money-back guarantee and certified lead-free products. Acquiring a product with a satisfaction guarantee offers peace of mind, assuring that you can return the system if it fails to meet your expectations. Additionally, opting for a lead-free softener ensures the safety of your drinking water.
