how water softener works

We have presented you with the best salt-based products that will help soften the water in your households. As you may have seen, some of these will reduce or completely remove harmful elements or even rust. You probably must be wondering how to decide on the adequate softening salt for the household? Don’t worry, we got your back here! We have prepared a detailed buyer’s guide, followed by some frequently asked questions. They will provide you with all the necessary information about choosing the product that best fits your needs.

Buyer’s guide

When do you need to introduce water softener salt?

Although there are some sodium-free softeners on the market, they won’t remove the hard water minerals. Minerals such as magnesium and calcium won’t disappear from the water unless you start using salts. Salt is crucial for the ion exchange. Except for salt and potassium chloride, no other minerals can be used to effectively purify water.

Here are some things to consider before purchasing softener salts:

  • The actual hardness of your household water – Depending on the substances in your water, it will be more or less hard. The larger amount of hard elements, the greater will be the consumption of salt.
  • Type of water softener – You can only need salt if your water softener is salt-based. Some devices work on other principles. Therefore, determine if you should or shouldn’t make the purchase.
  • Sodium-based vs. sodium-free salts – Both work in exactly the same way. However, if you are on a low sodium diet, or you plan to use the water for watering your plants or for your pets, you should reconsider buying the sodium
  • Crystals or pellets – Decide which form of salt you need for your household. Crystals are made of sodium-chloride in the process of solar evaporation. They are great for the house units with lower than average water usage. On the other hand, pellets are a better fit for homes with moderate to high water consumption.
  • Budget – potassium chloride is less common on the market and therefore more expensive than sodium chloride (the scientific term for the standard softener salt).


Can I fill my water softener to the top with salt?

You can add as much salt as you like. Some water softener users like to add one bag of salt per month. This is to make sure that the softening system contains salt at all times.

Other users, to spare their time, can fill up the salt all the way up to the top. This way, they can reduce the frequency of supplying the system. However, this way, you will need to remember to check up your softener tank from time to time. If you see only water you should add the salt again. The main goal is to maintain the salt above the water. It should look dry. This will push sodium concentration up and will result in nice and soft water.

Is it bad to let your water softener run out of salt?

If you let your water softener ran out of salt, it won’t be able to properly clean minerals, iron, and other harmful substances from the hard water. This will lead to your water leave rust or limescale stains on the surfaces in your kitchen or your bathroom.

Some people might tell you to just add salt to your softener tank-no big deal. The truth is that the moment salt is gone, hard water starts damaging your water fixtures and appliances. The limescale will start pilling-up in your pipes, which can eventually cause damage to the water tank.

How to clean a water softener brine tank?

Have you heard about a brine tank? If not, don’t worry. We will explain it now. Every water softener comes with two tanks- the brine and the resin tank.

The purpose of the resin tank is to hold beads. On the other hand, the brine one contains salt pellets. Now and then, these pellets break down, forming some sort of sediment in the tank.

It is highly beneficial to know how to clean the brine tank, as it will prevent harmful substances from damaging it. When the amount of salt is rather low, remove the “sludge” with a small spade or shovel. If the residue is too hard you will probably need to dig deeper or even hit that pile with some heavy tool.

You can also take a look at this instructional video:

How often should you add salt to the water softener?

You should check the softener’s brine tank at least once per month. The majority of experts agree that the level of salt should be three to four inches above the water level.

The level of the “hardness” of the water and the amount of water your household consumes will determine the quantity of salt you will need to pour into the softening device. According to the industry standards, a family of 4 with hard water will use one 40 lb of salt each month.
