A brine tank, or “salt tank” is an important part of a water softening system. It contains a mixture of salt and water that helps to remove hard minerals from the incoming household water supply, making it much softer. The brine tank must be filled with enough salt so that when the unit regenerates, the brine can be drawn out of the tank and into the water-softener resin tank, allowing it to do its job.

Yes, water is necessary for your brine tank to make sure it functions properly. The brine tank is used to store the salt needed to soften hard water and must remain full of water at all times to work correctly. If there isn’t enough water in the brine tank, the softener won’t be able to soften your water.

How Much Water Should Be In Brine Tank?

The brine tank should contain a minimum of one-half to two-thirds full of water. different water softener models vary in size, so the amount of water they will hold also varies.

Why Is There No Water In My Water Softener Brine Tank?

If your water softener brine tank is empty, it could be for a variety of reasons. One possible cause is that the salt bridge has been formed inside the tank, causing a blockage and preventing the delivery of salt from the bottom to the top of the tank. The second reason why there may not be any water in your brine tank is that the float valve may have stuck in an open position and not closed as it should. This will cause the water to run continuously through the unit and out of the brine tank, leaving it empty.

  • The Water Level Is Below The Salt Level: There are a few reasons why there could be no water in the brine tank of your water softener. One of the most common causes is that the water level has fallen low enough for the salt to start settling on the bottom and prevent any more from entering. This can happen if you have been using too much salt or regenerating too frequently. To check if this is the issue, simply remove the lid from your tank and look inside to see if the salt has settled on the bottom and if there is no water above it. If so, you will need to add more water until it reaches a level just below where the salt starts.
  • Loosely Packed Salt: When you fill the brine tank with salt, the salt must be loose and not packed down. Packed-down salt will block the flow of water into the brine tank, resulting in no water in your softener. You can easily fix this problem by stirring up or breaking apart any blockages with a spoon or spatula.
  • Water Softener Only Adds Water During Regeneration: The most common explanation for why there is no water in your brine tank is that the water softener only adds water during regeneration. During this process, salt and other chemicals are used to clean out hard deposits from the resin beads in the softening unit. This salty “backwash” then flows into the brine tank where it sits until the regeneration process is complete. After this, the brine tank should be empty and any remaining water will evaporate over time due to evaporation. If there is water in your brine tank after regeneration and it isn’t going away, it could indicate a problem with the system.
  • Water Softener Is Regenerating And Has Not Added Water Back: If your water softener is in the middle of a regeneration cycle and has not had time to add any new water back into the brine tank, there could be no water in the brine tank. Water softeners use salt to remove calcium, magnesium and other mineral ions from hard water during the regeneration process. During this process, all of the water that was in the brine tank is used and not replaced until after regeneration has been completed. To know for sure if this is what has happened, check the timer or settings on the control valve of your water softener to see how long it takes for a regeneration cycle to complete.
  • The Water Supply Has Been Shut Off: Your water softener brine tank won’t have any water in it if the main water supply has been shut off. This can happen due to a power outage, plumbing repairs, or a city-wide shutdown of the water system. If this is the case, the only solution is to wait until the water supply is restored and then check your brine tank again.
  • Your Water Softener Was Put Into Bypass Mode: The most common reason there is no water in the brine tank of a water softener is that it was put into bypass mode. This means that instead of running through the water softener, untreated hard water is being used to supply your home and appliances with softened water.
  • Your Water Softener Lost Power: If a power outage has occurred and the water softener was not plugged into an uninterruptible power source, then it may have lost its programming when the electricity went out. Check all circuit breakers or fuses to make sure they are in the correct position. If that does not resolve the issue, you may need to reprogram the water softener. Another potential cause for a dry brine tank could be that the system’s settings are not set correctly.
  • The Brine Tank Fill Tube Is Kinked, Clogged, Or Blocked: The brine tank in your water softener is connected to a tube that allows the softened water and salt to enter it. If this tube is kinked, clogged, or blocked, then no water will be able to get into the brine tank. To check if this could be the issue, disconnect the fill tube from its connection to the water softener and check if any water enters the brine tank. If not, then you will need to have the tube cleaned out, or replaced if needed.
  • The Brine Tank Valve Is Sticking: A common cause of water softener brine tanks not filling with water is a sticking valve. This valve, located at the bottom of the tank, controls the flow of rinse water that comes in from your home’s plumbing system and refills the brine tank after its contents have been exhausted during regeneration. If the valve sticks open or closed, the tank will remain empty. Cleaning and lubricating this valve can help solve the issue.
  • Old water softener: If you have an older water softener, it may not be working properly. There could be a leak in the tank or the valves are not working correctly. It is also possible that the brine tank was overfilled and caused a clog in the system, preventing water from entering the brine tank.

Is The Water To Your Water Softener Turned On?

The first thing you should check when you notice that there is no water in your water softener brine tank is to make sure the water supply to the water softener is turned on. If it’s not, turn it on and wait for a few minutes before checking again. If the water still isn’t present, then there may be another problem causing the issue.

If there is no water in your brine tank, the first thing to check is the float valve. The float valve is located at the top of the brine tank and should be floating freely on top of the water line. If it is not, then it needs to be adjusted so that it can open up and allow water into the tank.

How To Drain Water In Brine Tank?

Step1:Start by unplugging the power source or circuit breaker that supplies electricity to your water softener system. This is for safety reasons as we will be working with electrical components.

Step 2: Next, locate the brine tank and disconnect it from the main unit by unscrewing its hose connections.

Step 3: To ensure that all the water is removed from the brine tank, you will need to drain it. To do this, place a bucket or container underneath the tank’s discharge spigot and open it up.

Step 4: After draining all the water out of the brine tank, close the spigot and secure the hose connections back onto the main unit.

Step 5: You can then plug the power source or circuit breaker back in and you’re done! Your brine tank should now be free of water and ready for use again.


How do I know if my Brine tank is clogged?

The most common symptom of a clogged brine tank is that your water softener won’t draw in any new water to replace the water it has used up. If this happens, you’ll need to inspect the tank for signs of blockage. Check for any build-up of salt or dirt on the bottom and sides of the tank, as well as in the water line that leads to and from the brine tank. If you’re having difficulty locating the blockage, it’s a good idea to consult a professional.

What are the different types of water softeners?

Water softeners come in a variety of forms, including reverse osmosis systems, salt-based systems, and magnetic water conditioners. A popular type is a salt-based system. This system works by exchanging “hard” ions (calcium, magnesium) with sodium or potassium ions. The ion exchange process softens the water and eliminates scale build-up in your pipes. The brine tank is a key component of this system, as it stores and supplies salt to the exchange resin.

Do I need RO if I have a water softener?

No, you do not need a reverse osmosis (RO) system if you have a water softener. A water softener helps to remove hard minerals from the water that can cause scale buildup in pipes, appliances and other fixtures. However, it does not filter out many of the contaminants found in drinking water such as lead, chemicals, or microorganisms. If you want your drinking water to be free of these contaminants, then a reverse osmosis system is the best option for you.

Can I use filtered water in the water softener?

Water softeners work by removing minerals in hard water that can cause staining, scale build-up, and damage to plumbing. The brine tank is a crucial part of the water softener system; it holds the salt or potassium pellets used to soften the water. If there is no water in your brine tank, it could indicate a problem with your water softener system.


If you find that your water softener brine tank is empty, it could be due to a variety of causes. It is important to check the salt level in the tank, as well as look for any clogs or blockages in the piping system. Additionally, check for leaks throughout the entire plumbing system and make sure the settings on the water softener are correct. If all of these checks come up negative, then you may need to call a plumber to take a look at your system. With proper maintenance and care, your water softener should be able to provide your household with plenty of clean and soft water for years to come.
