This is one of the most usual questions regarding the consistent upkeep of a water softener. Most most likely it’s because the bulk of the water softeners ~ above the industry today put water in the salt tank in ~ the end of their regeneration cycle, so civilization will check out water as soon as they include salt to their system.

You are watching: How much water should be in my water softener brine tank

A standard water softener brine tank should have actually water in it all of the time except when it uses it come regenerate that is water softener resin. Some premium water softeners have actually the capability to only add water to the brine tank 4 hours before the water softener regenerates to help prevent salt bridging.

How much water and when water is put right into a water softener brine tank can depend on your water characteristics and also the kind of water softener that you have. Let’s uncover out if you need to be see water in her brine tank.

How much water must be in mine water softener brine tank?

Depending on just how your softener is set, the quantity of water that will be in your salt tank will vary yet for the many part, the water in her tank will be around one-quarter to one-half the the method up the tank.

The actual level the water in her brine tank is established by what brine dosage required to most effectively regenerate the water softener resin within of her water softener.

A reduced dose of brine will regenerate much less of the water softener resin if a larger dose of brine will certainly regenerate an ext water softener resin.

So if you have let her salt run down reduced than usual and see water in the tank, don’t worry if that is approximately one-third of the means up the tank. This is perfect normal and also most likely has been collection for that level due to the fact that it to be installed.

For optimum water softener performance you must be certain to save your salt level over the water level i m sorry is usually about one-quarter full, however do not overfill it. You should never fill her tank an ext than around a six-inch indigenous the top, this can encourage salt bridging and also does not benefit the mechanism in any kind of way.

Why is there water in a water softener brine tank anyway?

To the typical homeowner, seeing any kind of water other than the water the comes out of a faucet or showerhead have the right to be alarming till they understand why that is there and what it is offered for.

The salt tank the a water softener is the point where the fastened water device that is provided to soften the water that is provided throughout the residence meets the salt the it demands that is provided by the homeowner.

You have the right to think of the salt as the cleanser the the softener uses to clean itself of the hardness that it has removed from the water.

Here’s a quick video showing why there requirements to it is in water in her water softener brine tank.


While a water softener only uses the saltwater (commonly well-known as brine) in the tank for a brief amount of time, usually around 90 minutes. Most varieties of softeners include water to the salt tank in ~ the very end of their cleaning process.

The mechanism does this so the water can sit in the salt for a long duration of time and also become saturation with liquified salt. This salt-rich systems is dubbed brine, and it is what the water softener provides to eliminate the hardness that has built-up in the water softeners resin bed.

When have to there not be water in a water softener brine tank?

In many cases, there is water in the salt tank practically 100% that the time.

But most civilization don’t recognize this due to the fact that they don’t let their salt level gain low sufficient to view the water, which is good, store it up.

The just time that there is no water in a common water softener salt tank is during a short rinse cycle after ~ the brine solution has been used by the water softener come regenerate the water softening resin.

During the softeners regeneration cycle, the brine solution is attracted from the salt tank and also flushed v the softeners resin bed, clean it and also then rinsing the brine away.

After the brine has been offered up, the mechanism will have to replenish the water in the tank so the can end up being brine because that the following time the the device needs come regenerate (clean itself).

So there will usually be water in ~ the bottom of the salt tank if you have a water softener that supplies this most usual regeneration cycle.

The median water softener will have approximately three to six gallons the water in the at any kind of given time. The amount of water in the tank will count on the lot of brine necessary to regenerate the lot of softening resin in the system.

How does my water softener know how much water to placed in the brine tank?

The amount of water that a water softener puts right into its brine tank is usually measured by time that refill. The mechanism will just feed water into the tank for a preset quantity of time come dissolve the proper amount that salt that the device needs because that it to work.

Smaller equipment may have actually a tank of just seven customs in diameter and also forty-eight inch high through only around 1/2 cubic foot of resin in them and will use as small as around three gallons that brine to regenerate.

Other larger systems may have tanks as large as thirteen inch in diameter and are fifty-four customs high, these systems will have actually as much as 2 cubic feet that softening resin in castle needing as lot as six gallons of brine equipment for their renewal cycle.

It all relies on how huge of a system is needed to take care of the amount of hardness uncovered in the water gift treated.

Why don’t i see any water in my brand-new water softeners salt tank?

Water therapy is constantly getting better, and many of the much more advanced systems now available use what is dubbed a dried tank cycle.

This simply way that the salt tank will certainly not have actually water in it most of the time, with the exemption of part residual brine that might be leftover after ~ regeneration.

These more recent systems will fill the salt tank through the required amount the water usually about four hours prior to the mechanism will regenerate.

This will permit enough time because that the salt come dissolve into a brine systems while leaving the tank with very tiny water in the the majority of the time.

Check out this quick video on exactly how a “DRY” brine tank rejuvenation works.


This can be valuable in instances when the mechanism does not have to regenerate very often or if that only requirements to regenerate component of the time, favor in a guest house or if the house is only used seasonally.

Unlike a standard form regeneration cycle i beg your pardon will typically go v a backwash cycle, a brine draw, a brine rinse cycle and then a brine to fill cycle leaving water in the tank till the following regeneration.

This more recent cycle order will fill the salt tank come the suitable level and then let that sit for four hours and then do a backwash, brine draw, and also brine rinse, leaving the salt tank v virtually no water left in it.

Why is it better to only have actually water in a brine tank right before it regenerates?

Some services of this newer cycle set-up space that the salt will certainly not be sitting in water for expanded periods of time i m sorry can cause the salt to clump and sometimes develop salt bridges the leave an north void at the bottom the the tank and the salt does not dropdown.

Also, there will not it is in standing water for lengthy periods of time i beg your pardon can cause odors and also sometimes the expansion of bacteria.

No matter which system kind you have the amount of water in the tank need to only be 3 to 6 gallons or around one-third that the means up the tank.

If you uncover that the water in the tank has risen over halfway up the tank, the mechanism is likely not using every one of the brine the it is claimed to be, because of this not properly softening the water and also you should call your water system organization technician to have actually it checked.

What form of salt have to I usage for mine water softener?


*

Another great question! You go to the store and also you see a sign for water softener salt, and beneath the sign, friend see environment-friendly bags through red out, yellow bags the say pellets, blue bags the say crystals, and also so on and so on. So those the difference in between one bag and another.

Besides the price, the key differences in between these water softener salts are rather simple.

Blue or blue and also white bags are usually just salt crystals as the bag says. This salt has been mined native the earth, provided a fast rinse and also then bagged because that use.

This blue bag salt is usable for any type of water softening device although it does have a defect that makes it no the many recommended salt for non-electric water softeners.

The factor for this is due to the fact that it is mined indigenous the earth, so it has actually some dirt, grit and also other debris in it.

This debris goes into the salt tank and can periodically lodge in the salt tank fill shut turn off mechanism, i m sorry can cause it no to close up door off and also overflow the salt tank. This is not common but it deserve to happen.

Is pellet salt the best water softener salt?


*

Pellet salt is often, yet not only, uncovered in a yellow bag. This is salt that has been processed and cleaned.

This clean salt is frequently recommended because that non-electric water softeners since it does no have any type of debris in it the can cause the water shut-off valve to fail.

But this pellet salt has actually a fence to it. The pellets are made up of salt and also a binding agent.

This binder is non-soluble and also will clear up to the bottom of the tank. Over time, this binder will come to be several inches of mush in ~ the bottom the the tank wherein salt must be.

This accumulation will not allow enough salt to be exposed to the water and also therefore not provide a solid enough brine solution to appropriately clean the water softener.

This mush is no usually difficult to remove yet it can be fairly messy so you could want to have a service professional carry out it for you so they deserve to make certain that that is done properly, and also be certain to questioning them come make certain the brine float assembly is cleaned and set correctly as well.

What is the red the end for in the green salt bags?

The green bag salt is salt that consists of a little amount of an additive the helps to remove iron native the water. I just recommend utilizing this eco-friendly bag salt if her water has a high level of stole in it.

Although this salt will help to remove the iron indigenous the water, the iron is eliminated in the salt tank and will frequently settle come the bottom that the tank and also remain there until it is cleaned out by hand.

A water softener the is set correctly will remove a considerable amount of iron without any help from any type of additives in the salt.

Also, these additives can cause odors in the water and sometimes clogging of internal parts inside the water softeners regulate valve, so stop using any kind of salt the is no crystals or continuous pellets if possible.

For practically all cases I recommend using blue or blue and white bag salt without any additives and only pellets once using a non-electric softener system.

Should there be water in my brine tank once using potassium chloride?

The last kind of water softener salt that you could find in your local hardware store is potassium chloride. Unlike consistent salt (sodium chloride), potassium chloride is a short sodium different to using constant salt in water softeners.

This have the right to be one expensive selection as potassium chloride have the right to be around four times the price of regular salt and also a softener requires much more of it to properly clean the system.

People that are came to with limiting their salt entry may take into consideration using potassium chloride for wellness reasons.

Unfortunately, as soon as potassium chloride sit in water for a long period of time, the potassium chloride pellets have a propensity to clump together reducing the as whole surface area in which come get dissolved by water in the brine tank.

This is why once potassium chloride is to be used rather of regular salt, the is encourage to usage a “DRY” brine tank cycle fairly than the typical “WET” brine tank cycle.

Should over there be water in a “DRY” brine tank?

There will be water in a “DRY” brine tank to dissolve salt to be supplied by the water softener to regenerate the water softener resin.

The difference in between a “DRY” brine tank and a “WET” brine tank is that the “DRY” brine tank is only filled v water a couple of hours prior to the water softener is going come regenerate, if a “WET” brine tank is filled through water at the finish of the rebirth cycle and also the tank has water in it nearly every one of the time.

If you have actually your system set correctly, using regular crystal salt will leave minimal sodium behind after regeneration and also it is much cheaper than potassium chloride.

If girlfriend come across any salt in your neighborhood store the you are not familiar with, asking for aid from someone in the store and also read the materials on the bag itself.

Does water in a brine tank use all species of water softener salt the exact same way?

If the save employee states that they space all the same and also you can use any one that them, check for yourself and find the one in the blue bag or the blue and white bag as they should be the right rock crystal salt that will job-related fine for your system.

Or if you have a non-electric system, find the pellet salt through no additives that space usually in the yellow bag.

One last, but an extremely important note on what type of salt come use. There space systems that usage a softening media recognized as silica crystal.

This silica crystal comes in 2 different types and is a really unique media that is provided for distinct situations.

The very first type is only used when the pH that the water is below 7.0 (acid water). The is provided when the water has actually hardness, low pH and also has a high quantity of iron.

This resin not just will soften the water and remove the iron, however it has actually the capability to progressive the pH that the water as well. The second form of this resin is also for softening the water and also high steel removal yet works on water with a pH the 7.0 or higher.

It has actually been discovered that this unique media can have a reaction through additives that are in water softener salts. Using any kind of salt as well as the blue or blue and white bag salt can cause odors in the water and over time can cause the media to shed its ability to soften water and also remove iron.

So if your mechanism says silica crystal on the be sure to only use the salt in the blue or blue and white bags.

To sum Up!

So be sure to check your salt tank regularly and also never permit it run out the salt. My dominance of ignorance is come treat your water softeners salt tank as you would certainly the gas tank in her car. Girlfriend don’t have to keep it totally full the salt all the time yet you never ever want to let it acquire empty.
