how often to regenerate the water softener?

You can have heard a sound that your water softener was regenerating at one time or another. 

Of course, you may be curious about how your softener works and whether it is performing as it should.

Many homeowners have many questions about the effectiveness of their water softening.

This guide will answer the question, “How often to regenerate water softener?”

I will be talking about the regeneration process and factors that affect the frequency of the regen cycle.

You will also get detailed information about outdoor water softener regeneration.

What Does Water Softener Regeneration Mean?  

Regeneration is an essential part of water softener work. An unusual regeneration schedule is one way to tell if something is wrong with your softener.

The regeneration process removes hard minerals from the resin bead of your water softener. These beads wouldn’t function properly without regeneration.

Regeneration depends on how much water softener salt (potassium chloride) you add. It will restore the resin beads with the necessary sodium ion to perform their task correctly.

Are you still unsure? It’s okay; it works like this.

The softener’s resin beads pass water from the local municipality or another water source. 

These beads contain sodium, which conducts an ion exchange, pulling minerals out of your hard water and replacing them with sodium.

The beads eventually can block hard minerals and are unable to exchange these efficiently. 

That is when regeneration kicks in. It clears the beads of minerals and makes them more suitable for sodium-ion exchange.

How Often Should a Water Softener Regenerate?

How Often To Regenerate The Water Softener

The best water softener can regenerate according to a set schedule. The system will initiate the process automatically in the morning, approximately once per week. 

Modern softeners with this function will allow you to adjust the interval using a control module. 

For more information, refer to the manual of your softener.

Other systems regenerate according to user needs. The system will regenerate more frequently if your household has more water usage to avoid interruptions.

An ultra-efficient best water softener can regenerate every day. If it regenerates on demand, your owner’s manual will provide information.

Phoenix’s demand-based water softeners will regenerate within two to three days. Although it is rare to go more than a week without a regen cycle, it happens.

What Happens During Regeneration?

During regeneration, the softener floods resin with brine water. This “cleanses” hardness minerals from the resin and sends them down the drain.

Now the softening resin inside your softener becomes clean and is ready to soften your drinking water.

That makes water softener the best option for softened water with the help of a correct salt level. If you want to know in brief “how to treat hard water,” please have a look.

This process can be weekly, depending on how much drinking water you use, or your home will have soft water all the time.

These Causes Can Often Affect To Regenerate Of the Water Softener

Iron Levels in water

Iron can cause severe damage to water if its present in the water. Most outdoor water softeners can remove low-to-medium levels. 

Iron can treat hard water minerals like calcium and magnesium and then exchange them for sodium chloride in the softening tank.

You should note that iron levels exceedingly high may mean your water softener cannot remove it completely.

Resin Tank Capacity

Your resin tank’s capacity also influences how frequently your softener will regenerate.

A larger brine tank can hold more resin beads, allowing for a greater sodium volume.

The salt tank will hold more sodium, which means it can also have calcium and magnesium ions after removing them. 

It allows the resin to be more stable, allowing for effective water treatment over several days rather than regenerating every day.

Clogged Line

The entire process of softening will be affected if your salt tank doesn’t fill or empty properly.

Water softener salt must be dissolved to create a sodium-rich substance called brine.

It is necessary for ion exchange. The brine is sent to the softening tank, where it regenerates resin beads.

Your system could need to be regenerated more frequently if there is a blockage or slow rinse in its brine line due to a salt bridge.

Resin Deterioration

The best softening resin in its prime condition is the new one. A resin structure may become less resilient over time due to salt level and water usage.

The system will need to restart the process more often as fewer sodium chloride ions are available for ion exchange.

Control Valve

Regeneration settings will depend on the type of control valve that your softener uses. 

A water softener with a built-in clock will follow a set schedule and regenerate according to a predetermined timer.

The metered softener is slightly different because it regenerates according to the household water supply.

It is helpful for people who have high water consumption, such as those who live in their homes for several days before moving on to work for a few days.

Water hardness

Your water’s hardness ions can impact how often your water softener regenerates. 

The more complex your water softener system has to work to remove calcium and magnesium, the harder it will be.

If you have high water hardness, your system might need to regenerate every day. 

It will ensure that your household has constant access to soft water.

Use of Water

Knowing your daily water consumption will make it easier to answer questions like “How often should my water softener regenerate?” 

Your system will need to recharge more frequently if you have a large family or use more softened water each day.

The system treats more headwater per day, so the resin bead will get saturated faster and requires more softener regeneration.

System Age

What is the frequency at which your outdoor softener will regenerate as it gets older? 

Your water softener will likely regenerate more often as it ages – maybe every day instead of every two to three. 

It is particularly true for single brine tank softeners.

How Does It Determine How Often To Regenerate Water Softener?

Water softening uses two regeneration. Depending on the valve, there are two types of regeneration: demand regeneration or time-initiated.

Demand Regeneration

The demand generation settings keep water usage and put the softener in “regeneration mode” when a certain amount of water flow passes through the softener. 

It works similarly to your Smartphone. If you have many apps open and use your phone frequently, the phone will need charging more often. 

The same principle applies to demand regeneration. The frequency that your unit needs washing will depend on how much water you use. 

If you have guests at your house and use more water than usual, your unit will need more frequent regeneration.

Both methods of regeneration have proven successful over the years. 

The system regenerates when it has exhausted its softening capacity.

That allows it to regenerate on a particular day regardless of whether it requires regeneration.

Time-initiated Regeneration

The control valve’s clock triggers the system to regenerate after a specified number of days or at a low water consumption time (the default setting is usually 2 am). 

The process will be repeated at least once per week. The valve settings are determined by a water treatment professional based on your hard water quality, resin tank size, household water usage, and other factors.


What does water softener regeneration sound like?  

Some sounds sound like water flow or a running motor. Is true? It is often cleaned with saltwater or brine solution.

You will hear the brine solution rubbing against the resins during regeneration. It is a characteristic sound in water softeners.

How can I tell if my water softener has regenerated?

When the water softener regenerates, you will often hear certain sounds. 

If you still get soft water quality, this could indicate that your softener has been regenerating well. 

If your water becomes hard or does not lather as fast, your softener might have stopped regenerating. 

Clogging the brine tank with a salt bridge or slow rinse can cause problems with softener regeneration.

How long does it take for a water softener to regenerate?

Regenerating small water softeners can take up to 90 minutes. During this process, many things happen. 

The softener’s resin beads get a flush, and then they are reinvigorated with salt pellets from their tank.

Can I use water while my softener regenerates?

Yes, if there is a bypass valve.

That will allow you to send water supply directly through your pipes without the need for a softener. 

You won’t use soft water if this is what you decide to do. It’s better to wait until the cycle of regeneration has ended to prevent your home from being damaged by hard water minerals.

How much water should a water-softener use to regenerate?

The water softener’s size will determine how much water is used for the regeneration process. 

If the softener is large enough to house four people, the regeneration process will use 35-70 gallons

The number of hardness minerals present in your water will affect how much water is used for regeneration. 

The softener might only need 20-25 gallons of water if your water is low in hardness minerals.

How to stop water softener regeneration?

How Often To Regenerate The Water Softener

You can stop an electric softener from regenerating by pressing (and holding down on the water softeners).

The water softener will then go through each regeneration cycle until it stops rushing water through the system.

Some electric water softeners require that you use two buttons to speed up the softener’s regeneration. 

There are many options, but the most common combination is the “Next” or circle-shaped button and the up or down buttons.

What percentage of water is emitted from a water softener in regeneration?

Water used for softener regeneration will vary depending on its hardness ions. 

Regeneration can take 20-25 gallons for some softeners. 

It may seem like a lot, but it saves you water that could have been wasted or damaged by water-using appliances like washing machines, and water heater.

What can I do if I am still unsure?

Some POE water softeners might be more effective and different than others.

Although most regeneration is based on water use, some issues can be caused by faulty valves or conversations.

If you have any questions about your system or need assistance understanding the user manual or settings, I recommend calling a professional plumber.

Professional advice is a great way to ensure that you are getting soft water 24 hours per day. It will make your investment worth it.

Is it possible to regenerate water softener more often than you need?

If your water hardness is high, then regeneration will most likely occur daily

Some softeners can regenerate multiple times per day, while others may only need once a month. 

Experts agree that frequent regeneration is best because they keep the resin bed active.

How do I set the water softener regeneration cycle?

With the most recent technology, hard water softeners allow you to control the frequency of regeneration on your control valve.

Scrolling through the menu will reveal an option to select and modify how often to regenerate water softener?

If you want to reduce your softener salts (potassium chloride) and water consumption, I recommend reading your manual.
