How Much Water To Add To Brine Tank After Cleaning?

In a water softener, a brine tank is vital to the ion exchange process, due to which the brine tank must be clean at least once a year. These water softeners eliminate limescale from the water, and for their constant working, you need to maintain it.

Another reason for cleaning brine tank is the quality of water softener salt is used. So cleaning the brine tank is essential.

Do most people ask how much water should be added to a brine tank after cleaning it? It is highly recommended to add plenty of water to the brine tank after cleaning it. But the actual amount of water in the Brine tank depends on the type of brink tank you own.

In this article, we will explain how much water to add to the brine tank after cleaning? So this will help you to remove your queries.

How Much Water To Add To Brine Tank After Cleaning?

too much water in brine tank

Depending on the type of brine tank you have, you will need different amounts of water. Generally, water softeners consist of a tall and narrow softener tank and a shorter and wider brine tank. 

While some models use a combined water softener and brine tank, you will still have to soften your water regardless of which type you have.

Furthermore, brine tanks can be wet or dry:

1. Wet Brine Tanks

Most older water softeners have a “wet” brine tank. The brine tank will, therefore, always be filled with water. At all times, this kind of brine tank generally has 11-23 litres (3- 6 gallons) of water. 

The amount of water would be around 15-25 cm (6-10 inches). Even between regeneration cycles, water will remain in your tank. Having a higher level of salt than water may prevent you from seeing the water.

2. Dry Brine Tank

You may have a “dry” brine tank if you have a new water softening system. When you don’t have water in the brine tank of your water softener, it will take about an hour or two for your softener to go through its regeneration cycle. 

Between cycles, your softener should not contain water.

How To Identify Between Wet And Dry Brine Tank

If you have a wet or dry brine tank on your water softener, you can identify it in a couple of ways. Having a digital valve in a newer system means you have a “dry” brine tank.

Contacting the water softener company where you purchased it is the best way to find out.

What To Consider Before Adding Water To The Brine Tank

How Much Water Should Be in My Water Softener Brine Tank?

1. Water Level Should Be Slightly Lower Than The Salt Level

In your water softener, there is a brine tank that holds the salt. Always keep your water softener brine tank slightly lower than its salt level.

As a result, the brine must be in a sufficiently concentrated state to absorb the salt and allow it to absorb the water.

The water sitting above the salt in your brine tank is not in direct contact with the salt, so that it won’t be absorbing it at the same high concentration as the water sitting below the salt. 

Therefore, you should always ensure that your water level is below the salt level.

2. Brine Tank Should Never Be Full Of Water

The brine tank in your water softener should never be full of water. Even if only half of the brine tank in your water softener is complete, you have a problem.

When the brine tank of your water softener system is full of water, it won’t be able to draw the solution out during regeneration. Your water will become hard as a result. 

Your safety float will be engaged as soon as your brine tank is filled with water.

Indicators That Your Water Softener System Is Full Of Water

When your water softener system is overfilled with water, you will notice a few key signs. Among them are: 

  • You have hard water because your water softener isn’t regenerating correctly.
  • The taste of your water is salty.
  • The water lines are filled with brine. 
  • There is a clog in your faucet or toilet.
  • The flow of water weakens

3. Check Your Drain Line

The brine solution is sucked out of the brine tank during regeneration. The water cannot be drained from the tank if the drain is blocked, frozen, or kinked.

So, it is highly recommended to check your drain line and to clean it.

4. Check The Valves

Your water softener’s entry valve, usually located at the back of your unit, controls the flow of water into your system.

 Your brine tank may begin to fill up if your valve becomes damaged, clogged, or broken. 

Trying to remove and clean the valve can clear clogged valves. A replacement part will need to be ordered from a professional if it is damaged or broken.

5. Check Your Float Level

If your float valve is set too high, water will also fill up your brine tank. As a result, the excess water could build up over time since your system might not be able to get rid of all of the water after each discharge cycle.

6. Check Your Safety Float

Safety floats are built into most water softener systems. Within the plastic cylinder marking the salt level inside your brine tank, you’ll find this device.

In case too much water is being added, this mechanism will shut off water flow into the brine tank. Your water softener will not cause a flood if the safety float is in place. 

When the safety float is malfunctioning, it won’t shut off the water flow when it should, causing your tank to fill up with water.

Procedure When Your Safety Float Is Sticking

When your safety float is sticking, you can try the following:

  • Lift the float out of your tank by removing the lid on the cylinder. To remove any clogs or debris, run it under hot water for a few minutes.
  • While the float is being run underwater, gently move it up and down to ensure it moves freely.
  • Make sure the small ball in the bottom of the float can also move freely.


Ensure your water softener is not in regeneration mode when you attempt to remove and clean your safety float.

Should There Be Standing Water in My Water Softener?

How Much Water Should Be in My Water Softener Brine Tank?

A water softener uses water for ion exchange and regeneration processes, so water standing in a brine tank is normal. But if your brine tank is half-filled with water and its taste is bad, like hard minerals, there is something wrong. These few factors cause this problem. 

  • The problem in brine line
  • Clogged salt inside the tank
  • Malfunction of the brine tank drain line, Issue with a drain line
  • Valve issues
  • Blocked injector
  • System malfunction

This standing water affects the performance of the water softener. In such a scenario, you should contact the company and ask them to resolve this Issue.

Final Words

After reading the above article, we hope you understood what amount of water will be added to the brine tank after cleaning.

Moreover, now you must know what must be considered before adding water to the brine tank.


How often should I add salt?

To make water softeners work properly, you have to add some salt to them. But how often should you add salt? It depends on the size of the brine tank, the nature of the water, and usage of water. For a large family, brine water softener, use more salt, and you need to add salt more often.

How much salt does the water softener use?

It depends upon the size of the softener and the nature of the water. To make your water softener functional, you need to add salt to it regularly. But normally, a water softener uses ten pounds of salt per week or approximately 40-50 pounds of salt per month.

How to clean a brine tank?

Depending upon its size, you can add 1-2 gallons of water in the brine tank and add 1/4 cup of household bleach in the tank. Now clean the tank with a brush. Let the solution sit in the tank for at least 15 minutes.

What do I do if My water softener is full of water?

There are a lot of factors that cause the overflowing of water in the Softener tank. 
Firstly check that the Brine line is properly connected with the float’s brine tank. Check the Drain line, and if the line has any blockage, it may lead to an overflow of brine tanks. You can also use a control valve for regeneration, and these valves efficiently control the flow of water.
