5 Types of Salt for Your Water Softener


Much like any appliance around your home, your water softener system will need some regular maintenance in order to keep running at its most efficient. One of the main things involved with this is replenishing the salt supply. As such, you may be wondering what your salt options are?

Sodium Chloride Options

These systems run off of salt (Sodium chloride), but that doesn’t mean you want to throw any old salt into the system. When looking at your options, it is important to keep an eye on the purity level of the salt. There are a lot of bulk salts that are loaded with water-insoluble material which – over time – will build up in your tank and eventually prevent your system from functioning.  The best options for sodium chloride often comes down to pellets, crystals or even salt blocks. While pellets are the most commonly used salt option for softeners, there is nothing wrong with block salt or crystals.

Salt Alternative: Potassium Chloride

If sodium chloride is not the right fit fit for you, that does not mean you will not be able to make use of a water softener system. You can use potassium chloride as an alternative in your brine tank. This is 99 percent sodium-free, which makes it the perfect option for households that are looking to reduce the amount of sodium they ingest.  While this alternative works great, its main downside is how much more expensive it can be. As such, potassium chloride can also be a little harder to find in stores as its price keeps it from being an extremely popular option. If switching from salt to potassium chloride, make sure to talk with a technician to make sure you are altering your brine tank levels the appropriate amount.

Tips for Salt Maintenance

One of the most important things you can do to help maintain your water softener is to make sure you routinely check on the salt level within your brine tank. This should be done monthly to make sure your system is always functioning as well as it can be.

Make sure that the brine tank is filled to about 4 inches above water level, but still 3-4 inches below the top of the tank. This is the zone where the softener system works best.
