If your area supplies hard water, there is a need of having a water softener system. This will help improve the quality of water used by your household since you will have soft water.

However, how much water should your water softener regenerate? Keep on reading to find out more about this process and stay in the know.

How Does a Water Softener Regenerate?

It is important to note that water softener regeneration takes place in the resin bed and is the key part of water softening. All the minerals causing water hardness are trapped in the resin. This is where ion exchange takes place. Then, brine, which is a saltwater solution flashes through the system to clean the hardness out of the water.

The block salt loaded into the water softener flushes the machine for 10 minutes during the regeneration process. Furthermore, each cylinder is cleaned one after the other. This ensures hard water is cleared out of the system and you get soft water to your home.

The water is then used to drive the salt solution, brine, and flush it for the next cycle. Additionally, a specific amount of water softener salt is required to complete the water regeneration process.

Importance of Water Softener Regeneration

Dealing with hard water in your home is not easy. Therefore, the need for a water softener system is vital. A water softener with an ion-exchange column will enable the calcium and magnesium ions responsible for water hardness to be replaced by sodium ions. This will help flush out the hardness minerals.

The hardness minerals are trapped in the resin when they come in contact. They are then removed from the water and the water becomes soft. After some time, the water softener resins need cleaning because the hardness minerals cover it completely. At this point, the process of regeneration occurs and the process of water softening starts again.

This process is a cycle that repeats depending on how much water you use at home. Therefore, once the water softener resin is clean again, it is ready to soften your water. Thus, you consistently have soft water for house usage.

How Much Water Should My Water Softener Regenerate?

Since having soft water for your household use is important, you may want to know how much water your system should regenerate. The system needs water to fill the salt bin to produce brine which is flushed through the filter media. This amount of water needed to produce the brine varies from one manufacturer to the other and also depends on how long the system has been working.

Furthermore, the volume of backwash and the amount of water used by your household also determine the amount of water regenerated. Normally, the water softener system is used properly,  it can use around 35 to 65 gallons of water during regeneration. This entirely depends on the size of the water softener.

On average, the water softener can discharge around 70.25 gallons for the regeneration cycle. This clearly shows the system needs a good amount of water to regenerate. Some may see this as a waste of water.

However, it is far cheaper to use extra gallons of water to filter and soften your water than to constantly call plumbers to flush the poisonous chemicals out of your pipes. What’s more, you will still need to pass some water through the pipes to be able to use the water again.

Also, knowing the level of water hardness can help you determine how much water will be regenerated by your system.  Therefore, you can get the measurement of the water hardness level, maybe in grains per gallon.

Importantly, you need to establish where to drain the water during the regeneration cycle. You may use a utility sink or a floor drain. All in all, it is important to know that the amount of water used by a water softener depends on the size of your water softener system.

How Often Should a Water Softener Regenerate

There are water softeners that have a schedule for regeneration. Therefore, the system automatically senses that it is time to generate and then initiates the process. This could be early in the morning maybe once a week. Moreover, some allow you to adjust the water regeneration interval through the control module.

The process is entirely controlled by your water softener system’s valve, “control valve”. This valve directs the system when the regeneration process will take, hence determining how long it will take. Therefore, you can set it for the period you want. Furthermore, if the water softeners regenerate based on demand, it can do so after two to three days.

However, other factors determine how often your water softener system regenerates. For example, the level of water hardness in your area, the amount of ion in water, the resin tank capacity, and the age of your system affect how often it will regenerate. Furthermore, the number of people in a household also determines how often your system will regenerate. The more water you use in your household, the more often your water softener will regenerate.

Therefore, you can check your system’s manual to see if it regenerates on-demand or not. If so, you can schedule it to suit your household’s needs. Therefore, it is important to understand your water softener regeneration system and its method to regenerate.

Some regenerate on a scheduled time whereas others regenerate based on demand. Additionally, checking your manual can help you know the method it uses hence help determine how often it regenerates.


There are so many effects of hard water used in the household. Therefore, there is a need for a water softener. The article has shown us the water softener regeneration process and what it entails.

Moreover, we have seen how much water your system can regenerate and so much more. Therefore, you need a water softener for soft water usage in your household.
