Water Softener Buying Guide

What to Consider when Buying

Here are some key considerations to keep in mind when looking to buy a system to soften water in your home.

Water softener solutions

There are different types of water solutions, including:

  • Salt-based water softeners : These salt-based water softeners utilise sodium and a brine tank to get rid of hard water ions to soften water. However, these salt based systems have to have resin beads and a brine tank or salt chamber to ensure effectiveness.
  • Salt-free systems: These systems use nano-technology to alter water’s atomic structure to soften it. They are ideal for use in places with moderately hard water supply.
  • Electromagnetic systems: These salt-free systems are quite small, making them ideal for smaller spaces. They use magnetic wires to alter the molecules thereby softening water.

Type of salt

Most softeners work using salt. It is important to keep in mind that this isn’t just any ordinary salt. It is a specially formulated salt that functions to remove any contaminants in hard water.

However, before you go ahead and buy salt to soften the water, you should make sure that the salt can work to soften the type of water flowing through your plumbing system. If you don’t know, just carry out a test then use the result to buy the right salt to extract the minerals, often in block salt.

Although salt cakes are mostly recommended, they may not always be ideal for some mineral compositions.


Essentially, when you buy a water softener with a bigger capacity and bigger filter, you won’t have to worry about maintenance for a longer time as compared to a smaller capacity softener with a small filtration system to get softened water.

Therefore, if you have a big hard water problem, you may need to dig deeper into your pockets to get a larger capacity water softener to have your water softened.


Before you buy any water softener, make sure it is efficient enough to handle your hard water problems at home. Therefore, you have to consider the salt capacity it can accommodate, the size of its reservoir and how long one supply of salt can last.

Also, you should factor in the duration it will take you to change your filters. You may be tempted to go for a cheaper softener but it may end up being very costly in the long run.

Bypass valve

Inasmuch as it is wise to install a softener that includes a bypass system, ensure the bypass valve in the system. It will allow you to turn off water flowing through it for maintenance without disrupting the flow.

Ease of installation

Always go for a water softener that is relatively easy to install as compared to systems that may require you to run into extra costs just to seek the services of a professional plumber to do the installation for you.

Check out our post here on How to Install a Water Softener if you are ever considering a DIY installation.
