Have you recently started using a water softener and wondered how often to regenerate it?
Know that water softener regeneration depends on various things, such as the regeneration method and factors affecting it.
Throughout this article, I have explained everything regarding understanding regeneration and how long it takes, and even more!
Understanding the Process of Regeneration
The regeneration process of a water softener is flushing out minerals it catches from hard water so that new water can be softened. Hard water is softened when sodium ions replace calcium and magnesium ions in the water. Resin beds are used to carry out this process.
The water softener must clean the resin bed when it becomes saturated with harsh minerals to maintain this system’s effectiveness.
A water softener has several technical components, but regeneration is critical. The resin must be cleaned out with a saltwater solution (brine) after it has trapped all the hard minerals it can capture.
The water softener’s design, size, and efficiency determine how many liters are used for each regeneration.
The beads are initialized with a basic sodium ion, ensuring their negative charge before sending them through the water. In contrast, magnesium and calcium minerals in water are positively charged. A positively charged mineral like magnesium or calcium can be held in place by negatively charged beads before the negatively charged beads release a harmless sodium ion.
Water automatically gets softened after the hard minerals have been successfully removed.
To ensure that hardness minerals are removed from the resin beads, the resin beads are continuously flooded with saltwater during the regeneration process. It is now possible for the water softener to function normally again after the resin beads have been cleaned.
Salt brine is sent onto the resin beads over five primary stages of the water-softening regeneration process to remove accumulated hardness minerals effectively.
Here are the five main stages of the process:
- Fill – A salt storage container is included with the water softener. Regeneration begins with water flowing into this salt storage container, which dissolves the salt in the water and forms a brine solution. Add a brine solution to the water to remove hard mineral deposits from the resin beads.
- Brining – The brine solution is sent from the salt storage tank to the resin tank, where the resin beads are stored during the brining stage. Hard minerals will be dissolved in the salt brine at this stage.
- Brine rinse –
A brine valve will shut off after a certain amount of brine solution has been used for regeneration. This will cause the water to flow down the same path but without the brine solution. Then, minerals and brine waste are properly drained from the resin tank into a nearby drain.
- Backwash –
During this regeneration stage, water travels upwards through the large resin tank faster, flushing out any remaining sediments, such as iron and dirt. Then finally the water discharges water softener backwash.
- Fast rinse –
To rinse the resin tank quickly, water is pumped quickly down the resin tank after the backwash process has finished. By passing the water through the resin beads, these remaining brines will become attached to the beads and be removed from the lower portion of the tank. Water softeners cannot begin the softening process again until this stage is completed.
Salt brine solution, a combination of salt and water, is the main treatment used during the regeneration process.
When Should a Water Softener be Regenerated?
If you’re wondering how to know when a water softener has to regenerate, the answer is that it depends on several factors. In addition, it depends on the type of regeneration the system uses.
Let’s first look at the factors that help you decide the frequency of the regeneration process.
Factors that influence the frequency of this cycle include:
- Hardness of the water you consume.
- How much iron is in your water?
- Your water consumption.
- The capacity of the resin tank of your system.
- How old is your system?
- Degradation caused by oxidants and other chemicals, such as chlorine.
It’s common for a water softener to initiate the regeneration process as soon as the control valve indicates its time. Softeners can regenerate using two different methods:
Regeneration on demand –
During a regeneration process based on demand, the control valve keeps track of the amount of water consumed before starting the regeneration. The process begins only after a certain amount of water has been sent through the softener. Demand regeneration ensures that the resin beads will always be cleaned after they reach a certain level of inefficiency. This is true even when hard water contains a wide range of contaminants.
The regeneration process can occur more frequently if you use more water during the week. When guests stay at your house, your water usage tends to increase, and this method should be preferred.
Regeneration triggered by time –
Regeneration is triggered by time and begins only after a certain period. This method does not consider water use during the regeneration process. The regeneration process will still occur at the same interval, even if you didn’t use water during the week. A clock will be mounted on the control valve to tell the water softener exactly when to start regeneration.
You’ll need to consider two settings to get the most accurate results.
First, you will need to establish how many days are between each regeneration cycle. In addition, it is important to determine what time of day the regeneration will be done.
Ideally, this process should happen overnight when water use is low, so it is advisable to do it during low water use periods.
Both processes will soften hard water entering your home or business, but demand regeneration is considered more efficient, effective, and reliable.
Demand regeneration allows the water softener to be cleansed only after the resin beads have reached the end of their useful life. The time-initiated regeneration, however, could filter the water even before or after the resin beads have been exhausted.
How Often Should Your Water Softener Regenerate?
The regeneration of water softeners does not have a clear timeline.
A timed regeneration schedule is set up for some water softeners. The system automatically initiates this process once a week, usually during early morning hours. Most modern softeners have this functionality and a control module that allows you to adjust the interval. You can find more information about this in your water softener’s manual.
Regeneration is also performed based on user demand in other systems. To prevent interruptions, the system will have to regenerate more frequently for a household that consumes a lot of water.
Several ultra-efficient softeners are capable of regenerating daily. You can find information in your owner’s manual if it regenerates based on demand.
It takes two to three days for most demand-based water softeners to regenerate. In rare cases, you won’t cycle for a week.
There may be a significant difference depending on the source water’s chemistry and the unit’s size, which determine the period for water regeneration.
Thus, manually scheduling the regeneration process on a timeclock unit is possible. However, many water softeners nowadays will regenerate automatically when they reach a predetermined ‘gallons to regen(regeneration)’ level.
When the resin bed reaches a predetermined hardness level, some units trigger regeneration.
REMEMBER – It is false to believe that the more frequently a softener regenerates, the better. You will waste salt and water and use unnecessary electricity and water if you program a system to regenerate too often.
Should I Manually Regenerate my Water Softener?
Whenever you need to regenerate frequently, you should use the demand regeneration method, which will manually regenerate your water softener.
The demand regeneration method is the best when it comes to the efficiency of both salt and water.
After a predetermined amount of water has been processed through the softener, a demand regeneration valve sends your softener into regeneration mode. It’s like a car needing more gas when you accelerate – the more energy you expend, the more you will require to refuel. In the same way, demand regeneration works. As your water usage increases, backwashing will become more necessary.
So, Yes! You should manually regenerate your water softener if guests stay at your home and your water usage exceeds usual.
How long does it take for Water Softener to Regenerate?
In general, regeneration takes about 90 minutes or more.
Depending on the size of the water tank, it may take more or less time to regenerate the water softener.
It takes a while for the water softener regeneration process to complete. Depending on the softener, it may take up to two hours to fully replenish the resin beads. Therefore, setting your unit to regenerate overnight is convenient, whether you do it every day or several times a week.
This will start the regeneration process on your water softener at 2 AM, ending around 4 AM. Due to households’ inactivity, regeneration must happen during this time.
REMEMBER – Water hardness levels and household water use determine how long it takes for each regeneration.
Additional knowledge –
A 25 percent water reserve capacity is required before the regeneration process can begin on the water softener. Resin beads will be at a 75 percent saturation rate during this reserve capacity. This means they will contain about 75 percent of the hard minerals they can accommodate.
For instance, you can expect to use 35-70 gallons of water for regeneration if the water softener is designed to accommodate a family of four. Read this to know what size water softener you need according to your consumption.
Water softeners may require only 20-25 gallons of water if the water does not contain high levels of hard minerals.
What to do If your Water Softener is Stuck at Regeneration?
A clogged connection may be causing your water softener to stay in regeneration mode.
There are many causes of these problems, including:
- Drainage line
- The Venturi valve
- Valve for the brine
Your water pressure may also be low, or blockages elsewhere in the plumbing system. You’ll need to call in an expert to diagnose the problem properly.

Does my Water Softener Regenerate Every Night?
If your water softener is of the correct size and programming, it should regenerate about once every three to five days. However, it should regenerate at least once every fourteen days.
A device that regenerates every night may be too small to do its job properly.
Should My Water Softener Regenerate Daily?
Some softeners regenerate daily, others that regenerate once a week, and others that regenerate just once every two weeks.
Various factors determine how frequently you need to regenerate your tank, including its volume, water use, and hardness. So, yes if you want, your water softener can regenerate daily.
How Often Does Water Softener Regenerate Itself?
Find out your softener’s method by consulting its manual (or by contacting the manufacturer/installer). Depending on the softener’s efficiency, some regenerate daily while others regenerate twice or thrice weekly.
Nevertheless, some units can regenerate as infrequently as once per week (especially older ones).
How to know how often my Water Softener Regenerates?
Several factors need to be considered to determine when your water softener needs to be recharged. It is also significant to consider the type of control valve that is present in your water softener.
The amount of water used in your home, the hardness of your water, and the type of water softener you have will all affect how often your water softener needs to be recharged. Checking the control valve regularly to see how much salt is left and how much water has been treated will help determine when your water softener needs to be recharged.
Be sure to keep these things in mind before you leave…
Stages of regeneration, when it should occur, and how frequently it should occur.
As and when necessary, adjust and change regeneration methods. Take into account how long the regeneration process is.
There you go! You have now thoroughly understood the regeneration process for water softeners. But you should also know whether to use your water softener while regeneration?
