Why Is My Water Softener Salt/Brine Tank Full Of Water?

If you have a water softener, it is important to know why your salt/brine tank may sometimes be full of water. The main reason is due to the regeneration cycle of the softener. During this process, the brine solution in the tank is flushed out and replaced with fresh water from the home’s main supply line. This water is used to flush out the calcium and magnesium ions that attach to the resin beads and cause hard water. As this process takes place, the salt and brine solution in the tank will be replaced with fresh water and this can lead to a full tank. A properly functioning softener should fill up slowly, as it only needs a small amount of water to rinse out the beads, so if your tank is filling up quickly it could be an indication of a problem that needs to be addressed.

If you have a water softener, then it’s likely that you’ve noticed the brine tank is filled with water. This can be concerning if you don’t know what to expect. Here, we’ll explain why your water softener salt/brine tank is full of water and what you need to do about it.

The water in your salt/brine tank is there to help with the regeneration process of your softener. During the regeneration cycle, a small amount of water is drawn into the brine tank from the main-water line. This creates a saturated brine solution that helps remove hard minerals from your home’s water supply. As the regeneration cycle progresses, the salt/brine tank will become gradually more full.

At the end of the regeneration cycle, the salt/brine tank should be nearly full. Once this is done, a strong brine solution will be flushed into your home’s water supply to replace hard minerals with sodium ions. After the process is completed, the water in the brine tank will slowly be replaced with fresh water from the main-water line.

2. A Kinked, Clogged, Or Pinched Drain Line : A kinked, clogged, pinched drain line can cause the water to back up in the brine tank. If a kink or pinch is present, it will need to be addressed as soon as possible. You may also have a clog caused by mineral buildup on the inside of the pipe. This can be taken care of by running a pipe cleaner through the line.

3. A Kinked Or Clogged Brine Tube : Another possible reason is that the brine tube inside the water softener has been kinked or clogged. The brine tube helps to draw salt and water from the tank, so if it’s blocked or kinked, it can prevent the tank from draining properly. To check for this issue, you’ll need to remove the top of the water softener and inspect the brine tube. If there are any blockages or kinks, you’ll need to straighten them out or replace the tube entirely.

4. A Cracked Brine Tube : If the brine tank is filling up with water and not draining, this could be caused by a cracked or corroded brine tube. The brine tube is responsible for carrying saltwater from the brine tank to the softener unit. Check for any signs of cracks or corrosion in the tube. If you find any damage, replace the tube as soon as possible.

A Leaking Brine Tube Fitting

5. A Leaking Brine Tube Fitting : If the brine tank water level is unusually high, it could be due to a leaking connection between the brine tube and the salt grid. This can cause water from the main tank to enter into the softener’s brine tank and fill it up with excess water. To fix this problem, you need to tighten or replace any loose connections near the brine tube fitting. If tightened, it should stop the water from entering into your softener’s brine tank.

6. A Brine Tube Salt Or Debris Blockage : Another common cause of a brine tank full of water is blockage of the brine tube, which can be caused by salt or debris buildup inside the tube. If this is the case, you will need to remove and clean out the brine tube in order to get your water softener working properly again. You may also need to check for any broken or cracked pieces of the tube and replace them if necessary. Additionally, you should ensure that your brine tank is correctly set up and connected to the correct parts of the water softener system so that it can function properly.

7. A Sticking Brine Valve : If the brine valve on your water softener isn’t working properly, it could be stuck open or failing to draw out any of the saltwater from the tank. This can cause a buildup of water in the tank and no regeneration cycle can occur. You should check your water softener’s manual for instructions to clean or replace the brine valve, or contact a professional for help.

8. Increased Water Hardness Setting On Water Softener: If you have recently increased the hardness setting on your water softener, it is normal to find more brine in the salt tank. This happens because a higher hardness setting requires more brine for regeneration, which means that your softener needs to produce more salty water and fill up the salt tank accordingly. It is important to check if all the settings are correct and that you have chosen the right salt for your system.

Malfunctioning timer : If the timer on your water softener is not functioning properly, it may cause the system to regenerate more often than necessary. This will result in an overfilled brine tank due to the additional production of salty water. In this case, you should check and adjust the settings of your timer or replace it if necessary.

How Do I Get The Water Out Of My Water Softener Tank?

1. USE A BUCKET: The easiest way to remove water from a softener tank is with a bucket. Begin by placing the bucket beneath the discharge pipe of your brine tank. Loosen and disconnect the clamp securing the pipe in place, allowing any excess water to flow into the bucket. Make sure you keep an eye on the level of water in the bucket so that it does not overflow.

2. USE A WET-DRY VACUUM: If you find that the brine tank is overflowing with water, another way to empty it is by using a wet-dry vacuum. Place the nozzle of the vacuum over the overflow hole at the top of the tank and start vacuuming out as much water as possible. Be sure to check for any debris that can be stuck in this area, as it can clog the drain. Once you finish vacuuming, use a towel to dry off any remaining water. You may need to repeat this process several times if the tank is still filled with water.

3. DUMP THE WATER: The third step is to dump the water out of the brine tank. To do this, locate your drain hose and attach it securely to a floor drain or other appropriate area for draining out the water. You may need to use a sump pump if you don’t have access to proper drainage. Once the hose is connected, open the valve on the brine tank to allow the water to drain out. Make sure all of the water is removed from the tank, then close the valve when done.

4. DO A MANUAL REGENERATION CYCLE: If the salt level is low, adding water to the tank will not help. You will need to do a manual regeneration cycle on your water softener system. This process flushes out hard minerals from the resin bed in order to restore its effectiveness. Before starting the regeneration cycle, ensure that you have enough salt in the brine tank for it to be effective. Refer to your owner’s manual for step-by-step instructions on how to perform the regeneration cycle.

How to Prevent a Water Softener Not Drawing

Use High-Quality Salt: The most common reason for a water softener not drawing brine is the use of poor quality salt. High-quality salt should be completely soluble in water and free from dust, dirt, or other particles that can build up over time and clog your system.

Clean The Brine Tank:

If the brine tank is too full of water, it may be due to a buildup of dirt or sediment. To clean the brine tank, drain all of the water from the tank and then wipe down all interior surfaces with a damp cloth to remove any dirt or sediment. Finally, fill the brine tank halfway with fresh water and add a solution of water softener cleaner to help remove any residual buildup. Leave it to sit for 8-10 hours before draining and refilling with fresh water.

Use a Resin Cleaner

Use a Resin Cleaner: Resin cleaners are a great way to help your water softener last longer. These cleaners, when added to the brine tank, can help break down hard water scale that has built up on the resin beads. Doing this regularly (at least once a year) can help keep your system running efficiently for years to come.

Perform System Checkups: Make sure to consult your user manual or hire a professional if needed. The most common answer as to why the water softener salt/brine tank is full of water is because of an over-filled brine tank. This occurs when too much salt has been added, causing the water in the tank to become supersaturated and overflow onto the floor. If this happens, it is important to turn off the water supply to the tank and drain out some of the excess water before adding more salt. You may also need to check for blockages or leaks in the brine lines, as well as inspect all connections to ensure they are secure and free of any dirt or debris.

Can A Water Softener Overflow?

Yes, a water softener can overflow if water isn’t draining properly from the salt or brine tank. This can happen due to a clogged drain line, improper installation of the brine tank float valve, or not enough air pressure in the brine tank. When this happens, saltwater will flow out of the tank and into the drain line. If not corrected, the accumulated water can overflow from the tank and cause a big mess.

Do I Need To Remove The Extra Water From The Water Softener?

Yes, you should remove the extra water from the brine tank of your water softener. This is because when there’s too much water in the brine tank, salt doesn’t dissolve properly and can clog up the system. Moreover, removing excess water ensures that it won’t overflow during its regeneration cycle.

Do I Need To Have My Water Softener Serviced When It Is Full Of Water?

Yes, if you notice that your water softener salt/brine tank is full of water, it is important to have it serviced as soon as possible. A technician can determine the cause of the issue and provide a solution. In some cases, the system may need to be cleaned or even replaced altogether in order for the problem to be resolved. If the system is not serviced in a timely manner, it could lead to further problems down the line. It is important to note that most water softener warranties require regular maintenance and servicing in order for them to remain valid. Therefore, if your warranty has recently expired or will soon expire, it may be necessary to have a professional inspect your system before any additional issues arise.

How To Drain Brine Tank On Water Softener?

1. Unplug the power to your water softener. This will shut off any power running to the unit.

2. Find the drain line from your water softener’s brine tank and locate it outside of your home or in a different area of your house where you want the water to be drained. Make sure the line is long enough to reach your designated area.

3. Attach a garden hose or other water drain pipe to the end of the brine tank line and secure it with a hose clamp.

4. Place the other end of the hose in an outdoor drain, pool, or other receptacle that can hold all of the water from the tank.

5. Open the valve at the bottom of your brine tank and allow all of the water to drain out into the designated area.

6. Once all of the water has drained, turn off the valve and remove the hose from both ends.

7. Plug in your power to your water softener and enjoy the freshly drained brine tank.

8. If needed, fill the brine tank with fresh water softener salt and then start a regeneration cycle to restore your system back to its optimal performance.

Why Is There Water In My Water Softener Salt Tank

The presence of water in your water softener salt tank is quite normal! This is because the brine tank of a water softener works by drawing salty water from the bottom up through a hollow tube. As this happens, the salty water passes over resin beads. The ions present in the dissolved salts are attracted to these beads and deposit on them, leaving behind softened water.


Why there is no water in my water softener tank?

The most common reason why your water softener tank is full of water is because it needs to regenerate. This process involves the brine tank refilling with water, which then causes the salt to dissolve and create a concentrated salt solution (brine) that can be used to wash away any hardness ions in the hard water. If you are using a water softener that is set to regenerate on a regular cycle, the brine tank will automatically fill with water when it is time for the regeneration process. Another possible reason why your tank is full of water could be because of a malfunctioning float switch or timer, which prevents the system from starting and completing its regeneration cycle.

How often does a water softener needs to be serviced?

Generally, a water softener should be serviced every six to twelve months. This means that salt levels need to be checked and replenished as necessary and the system should be inspected for any signs of wear or damage. During this service call, the brine tank will typically be drained completely in order to inspect it for any built-up scale or debris that could be interfering with the proper operation of the system.

Why is my softener counting down?

Your water softener’s brine tank is designed to save and reuse salt that has been used in the water softening process. When your water softener is working, it will draw a mix of salty brine from the tank to use in its cleaning cycle. As time passes, however, the salt concentration decreases and eventually needs to be replenished. When that happens, your water softener will start counting down the days until it needs to be refilled with salt. This countdown is designed to ensure that you have enough time to restock the tank so that the water softening process continues uninterrupted. If you let the counter reach zero without adding salt, your water softener may stop working.

Is boiled water better than RO water?

When it comes to water softener salt tanks, their purpose is to regenerate the resin beads used in a water softener. The tank holds brine solution, which helps break down hard minerals like calcium and magnesium that cause hard water. Brine is made up of salt dissolved in a large amount of water; this creates a salty solution that can easily remove these hard minerals from the water.

Can I cook with sulfur water?

It is not recommended to cook with sulfur water as it can cause an unpleasant taste and smell. Sulfur water also tends to corrode metal surfaces, which can lead to discoloration of dishes. Additionally, the hardness level of sulfur water can create soap scum buildup on dishes that cannot be easily removed. If you are using a water softener to remove sulfur from your water, it should be sufficient for cooking purposes. However, it is best to test the water quality before using it for cooking. If you have any further questions about the safety of cooking with sulfur-infused water, please contact a local plumber or talk to your local health department.


Water softener salt/brine tanks can become full of water for a number of reasons. If you notice an excess amount of water in your salt tank, it is important to investigate and identify the cause as soon as possible. The most common causes are related to the brining process, backwashing or too much water entering the brine tank. You can fix this problem by adjusting the regeneration settings, replacing the brine line or checking for clogs in the system. If you are unable to identify and repair the issue on your own, it is best to contact a professional plumber who can help diagnose and solve the issue.
