Water Softener Salt Prices – How Much Should You Pay?

Hard water can be a costly problem faced by many homes. Hard water contains concentrated amounts of calcium and magnesium which can lead to clogged pipes and tougher times heating the home. If you have too much hard water flowing through your home, you’ll likely incur some pricey bills every month.

The best way to combat the issue of hard water is to soften it with a dedicated water softener. Installing one of these machines in your home will quickly pay for itself to the point where you’ll rarely have to worry about pipe repairs or extreme water bills. The only added payments you’ll need to worry about will be maintenance fees and water softener salt.

How Much Does a Bag of Water Softener Salt Cost?

One of the most common costs you’ll encounter with a water softener is the salt it requires. Typically, you’ll find yourself purchasing the standard 40-lb bag filled with the necessary salt crystals.

So how much money will you need to set aside to replenish the salt?

Most 40-lb bags of salt cost anywhere from $5-50. You might find yourself paying quite often for this, but when compared to the money you’re saving by preventing damages caused by hard water, the $50 bag of salt seems pretty reasonable. Most of the top brands offer their bags for less than $25.

What’s the Most You Should Spend on Water Softener Salt?

Salt is rather affordable, so you shouldn’t be paying wallet-burning amounts for a bag of it. As we mentioned, the most we think reasonable for a 40-lb bag of salt is $50 and even that’s pushing it. Most of the best brands offer their bags for around $10 which will likely net you the same amount of quality in terms of purity and effectiveness as a $50 bag.

If a company is offering you a bag of water softening salt for more than $50, it’s likely not worth it. The price of a bag of water softening salt is based on the purity of the salt, not the quality of the company. Even the purest salts should only be worth $50 at most, so it might be beneficial to look around for more, cheaper options.

What’s the Least You Should Spend on Water Softener Salt?

Seeing a bag of salt lower than any of the competitors might be appealing, but there’s a reason those prices are so low.

As we alluded to earlier, prices are based on salt purity and a bag of salt that falls below the recommended price range will be of a purity that isn’t effective. You might be paying less for the bag, but you’ll have to purchase it more often to make up for the lost quality.

We’d recommend staying above the $5 minimum as this is where the purity of the salt begins to dwindle.

The optimal price range for a 40-lb bag of water softener salt would be anywhere from $10-$30 depending on the needs of your softener.

If your water tends to be polluted with more magnesium and calcium than is common, purer salt is recommended.

One thing to note is that the smaller the softener you have, the less often you’ll need to buy softener salt. Small softeners can actually be very effective. Here are some of the smallest water softeners that actually work quite well.

What is Water Softener Salt?

Once your water softener has been running for quite a while, it can build up the harmful chemicals that make up hard water. This leaves any water that’s pumped through your softener filled with calcium and magnesium. So, while the water softener cleans your water, it too needs a little bit of a clean. This is where the salt comes in.

Water softener salt is used to push out any calcium or magnesium that has built up in the softener over time and replenishes the walls with sodium.

The sodium in the water softener salt both clears out the machine itself and can then be used to purify the water itself.

A 40-lb bag of water softening salt is enough to refill your brine tank so that when the machine gets filled with the hard chemicals, you can easily flush it out and restore it to it’s cleaning phase.

How Does Water Softener Salt Work?

Sodium is a combatant of the calcium and magnesium typically found in hard waters. When you use a purified salt like that of water softening salt, the sodium pushes out the two hard-water chemicals and replaces them with the clean mixture in the salt. This ultimately leads to cleaner, softer water that won’t clog your pipes or drive up your water bills.

As for cleaning out the water softener, the salt acts as a way to replenish the interior of the machine. Over time, the water softener collects the hard chemicals which build up on the interior walls. This causes any water that flows through it to collect the magnesium and calcium, defeating the purpose of the water softener. When this begins to occur, the salt is pulled from the brine tank and collected in the main portion of the softener.

The salt pushes out the hard chemicals and replaces them with sodium so the walls of the tank are fresh and clean. Once this process is completed, the water that comes in will once again be purified and softened as needed.
