How To Fix A Water Softener Salt Bridge

If you feel your water softener isn’t working as it should or notice all your hard water signs returning, it’s time to check the brine tank for the water softener salt bridge.

But what is a salt bridge in a water softener?

Before diving into what a salt bridge in a water softener is, you should have complete knowledge about what a water softener system is and how it works.
Well, a salt bridge is a solid layer of salt that usually forms inside your brine tank due to high humidity, an overflowing brine tank, or infrequent maintenance. This layer of clumped salt, however, seems harmless but is the main culprit behind your water softener problems.

A salt bridge covers the entire width of your water softener tank and prevents water from dissolving the salt, resulting in ineffective regeneration cycles, and ultimately delivering hard water. Therefore, dealing with salt bridges before they cause havoc and mess with your whole water-softening system is crucial.

In this article, we’ll discuss the causes of salt bridging and ways to prevent them in the future.

Causes Of Water Softener Salt Bridge

Salt bridges are not always your or your water softener’s fault. Sometimes, trivial things such as humidity can contribute to saltwater formation.

However, many other factors contribute to water softener bridging, including:

High Humidity

Humidity is the main culprit behind water softener bridging because moisture in the air causes the salt to clump in the brine tank before it dissolves in the water. If you’re located in a hot and humid climate, your softener is more prone to getting a salt bridge.

Wrong Salt Type

Not all salts are created for water softeners. Sometimes, using the wrong salt type in the water softener results in faster recrystallization and water softener salt bridge formation.

Note: Always choose the salt type recommended by your manufacturer. 

Overfilled Brine Tank

An overfilled brine tank or water softener full of water is one of the major causes of salt bridge formation because it hinders the salt dissolution process, promoting bridge formation.

Infrequent Maintenance and Refills

The infrequent cleaning and maintenance of your water softener may accumulate undissolved salt particles and impurities at the bottom of your tank, contributing to salt bridge formation.
Keep in mind that you need to maintain your water softener from time to time.

How Do I Know If I Have A Salt Bridge?

One of the most important signs you have a salt bridge is when your water begins to feel like it did before you installed your water softener. All the hard water signs return and you’re left with stubborn limescale stains, dry, brittle hair, and soiled laundry.

Additionally, one of the best ways to check if you have a salt bridge is to do a visual inspection and poke the salt with a stick or broom handle.

1. Open the brine tank.
2. Observe the insides of the tank. If you notice a hard crusted layer, you’ve salt bridge formation in the tank.
3. Take a stick or broom handle and carefully produce the salt.
4. If it feels solid and hard and doesn’t break easily, it’s now confirmed that you have a water-softener salt bridge.

How Do I Remove a Salt Bridge?

If you’re one of those DIY enthusiasts, you’re going to love this!

Investing in a water softener is one of the wisest decisions you’ll ever make, but handling a salt bridge can get challenging.

Here’s how to remove a salt bridge in your water softener.

1. Cut off the water supply to your softener with a bypass valve of the incoming valve completely.
2. Take any tool with a long handle, such as a broom or stick.
3. Flip your tool upside down and try to break the salt bridge.
4. Now, tap the center of the bridge with your tool. Make sure you crumble it because cracking will damage the tank.
5. Keep tapping the salt until it breaks apart and falls into the tank.
6. Once broken, scoop out the salt chunks.
7. Pour warm water to dissolve any salt crystals clinging to the bottom of your tank.
8. Turn the water supply back on and run a regeneration cycle until all the existing salt is cleared.
9. Once your tank is cleared, add fresh salt into your brine tank for luxuriously soft water.

Is Your Salt at Fault?

Yes, the choice of your salt can impact the formation of salt bridges in your water softener.

It’s a known fact that not all salts are created equal. If you use table salt or salt with impurities, you’re more likely to face salt bridge issues in your water softener.

For water softeners, the recommended salt type should be high-purity salt especially designed for water softeners, such as evaporated salt or solar salt. These types of salts minimize the risk of salt bridge formation. Also, they dissolve easily in your brine tank, smoothing the water-softening process.

Additionally, it’s important to not overfill your tank with water because it largely affects the performance of your water softener. That’s because if you fill the brine tank to the brim, there’s less water surface area, taking longer to dissolve the salt in your tank. As a result, clumped, crystallized salt is formed. We recommend checking the user’s manual for tank filling to avoid inconvenience.

Furthermore, it’s crucial to choose the right type of salt as per your needs and the model of your water softener. Before choosing your perfect water softener salt, keep your water hardness levels, water consumption, and household size in mind.

Note: For long-lasting, consistent softening, consult your user manual for the manufacturer’s recommended salt type.

Preventing A Salt Bridge In The Future

To keep your water softeners running smoothly without those pesky salt bridges, here are some steps you can take to prevent them from forming in the future.

1. Always fasten the brine tank lid to keep your humidity levels at bay
2. Use the right salt according to your user manual. Never use regular table salt or impure salt because they are more prone to crystallization and clumping.
3. Avoid overfilling your brine tank to keep it working smoothly. Consult your manufacturer’s recommendations. Most softeners work the best with a ⅓ to 2.3 full range.
4. Clean your brine tank regularly and remove any salt residue and mineral buildup. Follow the user manual for cleaning instructions.
5. Store your water softener salt in a cool and dry place, ideally in an air-tight container to keep the moisture in control.

When to Call a Professional

Unlike most water softener problems, salt bridge softener can be tackled at home. However, sometimes, the DIY reaches its limit, and it’s now time to call a professional for help.

Here’s when it’s best to call the experts.

1. If you follow everything as per the user manual to remove salt bridges, the issue persists. A professional may help to diagnose the problem and provide a viable solution.
2. If you’re new to plumbing projects, your water softener may involve dismantling the components that can be too overwhelming for you. In such cases, an expert would help you handle the complex repairs and educate you with the necessary information.
3. When you think your water softener issue is beyond a salt bridge or if you’ve already ruled out the salt bridge formation. It’s important to call a professional for a thorough inspection. They can also recommend the best solution as per your needs and requirements.
