What Happens if My Water Softener Runs Out of Salt

Jump to Section

Hard water is a problem that many people face every day. Not only does it make cleaning your home harder, but it can also cause problems with your appliances and plumbing. 

Luckily, getting a water softener is the best way to get rid of these problems and inconveniences. In addition, making sure that your water softener's brine tank is always filled with the appropriate kind of salt is an important part of keeping your water softener unit running as efficiently as possible. 

If your brine tank ever runs out of salt, there are a few things that can happen. In this article, you'll learn what happens if a water softener runs out of salt and everything about water softening salts.

What is a Water Softener?

What is a water softener anyway? A water softener is a filtration system that is used in order to remove the magnesium and calcium ions that cause water hardness. These ions can deposit themselves on surfaces and cause all sorts of problems like clogged pipes, decreased soap efficiency, and dry skin and hair.

It softens water through a process called ion exchange. A water softening system can be applied to the whole house or can be used in industries. The main function of the water softener is to address hard water.

Hard water contains high concentrations of calcium and magnesium minerals, which buildup in your pipes and shortens your home appliance's lifespan like dishwashers and coffee makers.

Here's how water softeners work: Water softeners typically use sodium chloride (table salt) to remove hardness minerals from water. This involves an ion exchange process where the hard water ions are exchanged with sodium or potassium ions. This process is called regeneration.

During the regeneration process, brine solution flows through the resin bed and exchanges the hardness minerals for sodium or potassium ions.

Water Softening Salts

Water softener salts work with a water softener to eliminate the hard minerals in the water. Hard minerals pass through the resin beads in the water softener tanks. The water softener removes those minerals during the regeneration cycle. The salts help to clean the resin beads so they can continue to soften your water.

If you have a water softener, it's important to keep it full of salt so that it can continue to do its job. If the salt runs out, the water softener will no longer be able to remove hard minerals from the water. This can lead to a build-up of minerals in the water, which can cause problems with your plumbing and appliances.

No Salt Means No Soft Water

If you have a water softener, it uses salt to remove hard minerals from your water. Hard water contains high levels of calcium and magnesium, which can cause mineral build-up in your plumbing and leave spots on dishes and glassware.

Hard water is more than an inconvenience, it will build up on your hot water heating system, making it less efficient. Hard water can build up from the plumbing of your home, limiting the water flow through the house. The ion exchange process won't happen without sodium ions.

This means that you'll be missing all the benefits of soft water, including improved skin and hair health, easier cleaning, and less soap required for washing.

Limescale Buildup in Your Pipes

If you have hard water, there's a good chance you've noticed a white, chalky substance on your fixtures and in your pipes. This is limescale, and it's made up of calcium carbonate.

Limescale is not only unsightly, but it can also cause serious damage to your plumbing. The scale can build up and cause clogs in your pipes, leading to decreased water pressure, leaks, and even burst pipes. Water softeners are the best defense against limescale.

Because water softener eliminates scale-causing minerals, there's no way that scale can collect on your water fixtures. But if your water softener lacks salt, you won't enjoy softened water, and scale will be able to freely form.

Hard Water Minerals in Control Valve

When your water softener runs out of salt, it can no longer remove hard water minerals from your water. These minerals will build up in the control valve, which is an important part of the water softener. The control valve regulates water flow into the salt tank and controls the regeneration cycle. If the control valve becomes clogged with minerals, it won't be able to do its job properly.

Over time, the control valve will become so clogged that it will need to be replaced. This is an expensive repair, and it can be avoided by simply keeping your water softener filled with salt. If your water softener runs out of salt, the hardness minerals can have access to the important components of the control valve, including the piston chamber.

Brine Tank Overflow

If the brine tank overflows, it's usually because the water level is set too high. The water level should be set so that it's about an inch below the top of the brine tank. If it's set any higher than that, the saltwater can overflow into the home.

Obstructions can also cause issues with float control. If it gets clogged with salt or other debris in the brine assembly, take it out, rinse it and ensure it's working properly. The brine float may allow water to continue filling, eventually causing an overflow. This may lead to water damage in your home if the problem isn't spotted in time.

This issue is more common with older non electric water softeners than with newer electric systems. Non electric water softeners rely on single water shut off valve to stop water from filling your system's salt tank. There's usually a tiny bit of dirt in the bag of salt that you empty in your water softener's salt tank. This dirt will settle to the bottom of the salt tank as salt is dissolved for use.

Iron in Water

Another possible issue is iron in the water. If your water has a high iron content, it can cause the resin beads in the softener to become coated. This reduces their ability to remove minerals from the water. As a result, you may need to clean out your softener more often or use a special iron-removal filter.

Most water softeners are capable of removing low levels of iron as well as hardness minerals. But if your water softener is out of salt, there will be no sodium ion present to replace the iron ion. This means that your water softener is essentially useless, and iron will remain in your home's drinking water.

Permanent Etching on Your Glassware, Shower Door, and More

If you have hard water, you're probably used to dealing with a little bit of mineral buildup on your fixtures. But if your water softener isn't working properly, that mineral buildup can become much more pronounced. Not only will it be more difficult to clean, but it can also permanently damage your glassware, dishes, and shower door.

If your water softener runs out of salt, the resulting hard water will leave hard water stains and streaks on everything that it comes in contact with. A white film will cover your glassware. Though you may be able to clean them at first, they'll become a permanent etch in the glass in little time.

Your glass shower walls will start to look like they're frosted over from this white film, and they can never get as clean as they were before, no matter how hard you scrub. Your shower head will also be affected, and getting the shower water softener can be quite expensive.

Your bathroom's glass shower walls will begin to have a frosted appearance due to the white film, and they will never look as clean as they were before, no matter how much you scrub.

Hard Water Stains

If you have hard water, you're probably familiar with the stains it leaves on your fixtures. These stains are actually deposits of minerals that have been left behind after the water has evaporated.

These mineral deposits can build up over time and become quite difficult to remove. If you don't remove them, they will eventually cause your fixtures to corrode. If you have a water softener, it will help to prevent these stains from forming in the first place.

How to Ensure Your Water Softener Doesn't Run Out of Salt

Use a Smart System

A smart system is programmed to keep track of how much salt is in the water softener and will automatically add more when it gets low. This way, you'll never have to worry about your water softener running out of salt.

Check the Salt Level Regularly

Even if you have a smart system, it's still a good idea to check the salt level in your water softener regularly. That way, you can be sure that it's always full and ready to go. You can do this manually by checking the brine solution once or twice a week.

Once you know what your brine solution should look like, you'll begin to gain a better understanding of when you need to refill the salt tank. Knowing by eye when the tank needs refilling will make it less likely that your water softening system will ever run out of salt.

Keep Extra Salt on Hand

Even if you check the salt level regularly, there's always a chance that you'll forget to refill the tank in time. That's why it's a good idea to keep extra salt on hand, just in case. That way, you can quickly and easily refill the tank as soon as it begins to run low.

How Often Do You Need to Replace salt in Your Water Softener?

If you live in an area with hard water, a water softening system is an essential appliance. By understanding how often you need to add salt to the tank, you can help ensure that your system always has enough to properly soften your water.

The quality and brand of your water softener may affect how much salt it uses. Your salt quality and water quality also play a role. In general, you should check your water softener at least once in six weeks to ensure the salt level hasn't dropped.

This way, you'll have a better understanding of how much salt your water softener uses and how often your water softener regenerates. You'll be able to top up your salt accordingly without relying on reminders from your phone.
