How to Add Salt to Water Softener

The Importance of Adding Salt to Water Softener and How to Do It Properly

Water is a vital resource that we use every day for various purposes such as cooking, cleaning, and drinking. However, the water supply in some areas contains high levels of minerals such as calcium and magnesium, making it hard water. Hard water can cause damage to appliances and fixtures, leaving stains on clothes and dishes, and making it difficult to lather soap. To overcome this problem, water softeners are used to remove these minerals from the water. Adding salt to the water softener is an essential process that helps regenerate the resin beads and ensures that the system works effectively. In this article, we will guide you on how to add salt to water softener and the benefits it provides.

How to Add Salt to Water Softener Step-by-Step

Before starting, make sure that you have the following items:

Items Quantity
Salt As required by the water softener manual
Gloves 1 pair
Bucket 1
Funnel 1

Step 1: Turn off the Water Softener System

Locate the bypass valve on the water softener system, and turn it to the “bypass” position. This will stop the water flow to the system, and prevent water from entering the resin tank.

Step 2: Remove the Salt Tank Cover

Put on gloves and carefully remove the salt tank cover. The tank is typically located near the water softener unit.

Step 3: Check the Salt Level

Check the salt level in the tank. If the salt is below the recommended level, add the required amount of salt.

Step 4: Add Salt to the Tank

Using a funnel, add salt to the tank. Be careful not to overfill the tank.

Step 5: Clean up

Clean any spilled salt around the tank and replace the cover securely.

Step 6: Turn On the Water Softener System

Turn the bypass valve back to the “service” position, and turn on the water softener system. This will allow water to flow through the resin tank, and regenerate the resin beads.

Step 7: Check the System

Check the system’s salt level after a few days, and add more if necessary.

The Advantages and Disadvantages of Using Salt in Water Softeners


1. Reduces Maintenance Costs

Water softeners that use salt are effective in removing minerals from the water, preventing scale buildup and reducing maintenance costs associated with appliances and fixtures.

2. Mineral-Free Water

Softened water is free from minerals that cause scale buildup and leaves no stains on clothes or dishes.

3. Longer Lifespan of Appliances

Softened water prevents scale buildup, increasing the lifespan of appliances such as washing machines, dishwashers, and water heaters.

4. Skin and Hair Health

Softened water is gentle on the skin and hair, preventing dryness and irritation.


1. High Sodium Content

The use of salt in water softeners increases the sodium content in the water, which may not be suitable for people on a low-sodium diet.

2. Regeneration Cycle

The regeneration cycle of water softeners can use a considerable amount of water and salt, leading to increased water and energy bills.

3. Maintenance

Water softeners require regular maintenance, such as adding salt, to ensure their effective operation.


1. How often do I need to add salt to my water softener?

It is recommended to check the salt level every month and add salt as necessary.

2. What type of salt should I use in my water softener?

3. Can I use rock salt in my water softener?

Rock salt is not recommended as it contains impurities that can clog the system and affect its performance.

4. How do I know if my water softener is working effectively?

Check the system’s salt level regularly and monitor the water hardness. Test kits are available to measure water hardness levels.

5. Can I use potassium chloride instead of salt in my water softener?

Potassium chloride can be used as an alternative to salt, but it is more expensive.

6. How do I dispose of the salt from my water softener?

The salt from water softeners can be disposed of with household trash.

7. Does adding salt make the water taste salty?

The amount of salt used in water softeners is not enough to make the water taste salty.

8. Can I overfill the salt tank?

Overfilling the salt tank can cause blockages and damage the system.

9. Can I mix different types of salt in my water softener?

It is not recommended to mix different types of salt as this can affect the system’s performance.

10. How do I clean the resin tank?

It is recommended to hire a professional plumber to install a water softener to ensure proper installation and operation.

13. Can I turn off my water softener?

It is not recommended to turn off the water softener as this can cause damage to the resin beads and affect the system’s performance.


Adding salt to water softener is an essential process that helps regenerate the resin beads and ensures the effective operation of the system. It provides several benefits such as reducing maintenance costs, improving the lifespan of appliances, and preventing mineral buildup. However, the use of salt in water softeners also has some disadvantages such as increased water usage, higher sodium content, and regular maintenance requirements. By following the step-by-step guide and FAQs provided in this article, you can ensure that your water softener works effectively and provides soft, mineral-free water for daily use.
