Do you have a water softener or thinking about installing one? If you have any stone surface, especially marble or limestone you may want to think twice. How does soft water damage stone? The following article will help you understand the basics of soft water on stone surfaces.
Why Do I need a water Softener
Most of us are aware of those mineral deposits that build up around our facets and shower walls etc. They can be difficult to remove. The solution is to install a water softener which eliminates these deposits by removing the minerals in the water. However if you have any stone surfaces, especially calcium based stones such as marble and limestone, soft water can damage these surfaces. Now if your stone is not exposed to water than occasionally cleaning them wont really do much harm. If there exposed to water such as shower this can be a problem.
How does water softening work?
Water softeners work through a process called ion exchange which eliminates calcium and magnesium from the water. … As the hard water passes through the resin, the beads grab ahold of the mineral ions and remove them from the water. When the bead seizes the mineral ion, the sodium ion is released. Soft water also has a slightly acidic ph(6.5) which can dull and damage marble and limestone
Now keep in mind that most marble and limestone are made up of these same minerals and the flow of water over them can cause them to erode. This will result in not only dulling the surface but also causing the stone to break down.
So how do you prevent soft water from damaging your stone surfaces?
The most expensive solution would be to replace the stone with a non-calcium based stone such as granite, sandstone, slate or quartzite. These stones are silicate based and are generally not affected by soft water.
Water softeners use Sodium Chloride pellets which will damage marble and limestone. Using an alternative pellet such as Potassium Chloride will reduce the damage
Install a reverse osmosis water filtration system which will remove 95% of everything from the water including sodium. You can use this system in conjunction with a water softener.
Sealing the stone with a good quality stone impregnation sealer can also help reduce the Potential damage
If your considering installation a water softener be sure to contact a company that is familiar with the harmful effects this can cause. They will also be able to help you choose the proper system to keep your stone surfaces looking good.

How Does a Water Softener Work?
Ion Exchange Process
The core principle behind water softeners is the ion exchange process. This process relies on a resin tank filled with tiny resin beads, which are typically made of polystyrene. These beads are coated with sodium ions (Na+). When hard water flows through the resin tank, the calcium (Ca2+) and magnesium (Mg2+) ions in the water have a stronger attraction to the resin beads than the sodium ions.
The Softening Cycle
The water softener operates in cycles to regenerate and refresh the resin beads. The main phases of the softening cycle include:
Service Cycle: During this phase, hard water enters the resin tank. The calcium and magnesium ions in the water are attracted to the sodium ions on the resin beads. As a result, the calcium and magnesium ions stick to the resin, and the water leaving the tank is now softened.
Backwash Cycle: After some time, the resin beads become saturated with calcium and magnesium ions. At this point, the water softener initiates a backwash cycle. During this phase, the direction of water flow is reversed, and a strong stream of water flows up through the resin tank. This loosens any debris or particles adhering to the resin beads and flushes them out of the tank.
Brine Draw and Slow Rinse Cycle: In this phase, the water softener draws brine (a highly concentrated saltwater solution) from a separate brine tank and sends it into the resin tank. The high concentration of sodium ions in the brine displaces the calcium and magnesium ions on the resin beads. The calcium and magnesium ions are washed down the drain along with the brine.
Fast Rinse Cycle: After the brine draw and slow rinse cycle, the resin tank is rinsed again with a rapid flow of fresh water. This helps to remove any remaining brine and ensure that the resin beads are fully regenerated and ready for the next service cycle.
Regeneration
Over time, the resin beads will become saturated with calcium and magnesium ions and depleted of sodium ions. When this happens, the water softener enters a regeneration cycle. During this cycle, the brine tank is used to create a fresh brine solution, which is then used to recharge the resin beads by replacing the calcium and magnesium ions with sodium ions. This process ensures that the water softener can continue to soften the water effectively.
Salt Usage
Water softeners require salt to regenerate and create the brine solution. The type of salt used can vary, with common options being rock salt, solar salt, or evaporated salt pellets. The salt is added to the brine tank as needed, and the water softener will use it during the regeneration cycle.
Does a water softener increase the amount of sodium in the water?
Yes, a water softener can increase the amount of sodium in the water. The process of water softening involves the ion exchange method, where calcium and magnesium ions, which are responsible for water hardness, are replaced with sodium ions. This means that as hard water passes through the resin tank of a water softener, the calcium and magnesium ions are removed from the water and replaced with sodium ions.
The increase in sodium levels in softened water is generally minimal and typically within safe limits for most people. However, individuals on sodium-restricted diets or those with certain health conditions may need to consider the potential impact of softened water on their sodium intake. If you have concerns about sodium levels in your softened water, you can explore alternative water treatment methods or consider a water softener that uses potassium chloride instead of sodium chloride (table salt) for the regeneration process. Potassium chloride can be a suitable, lower-sodium alternative for water softening.
How many ppm does a typical water softener release?
The amount of sodium or potassium ions released into the softened water by a typical water softener can vary based on the specific model and settings of the softener, as well as the hardness of the incoming water supply. However, a general guideline is that a conventional ion exchange water softener can release between 15 to 50 milligrams of sodium or potassium per liter (mg/L) of water, which is equivalent to 15 to 50 parts per million (ppm).
It’s important to note that this range can vary depending on factors such as the water softener’s regeneration frequency, the size of the resin tank, and the hardness of the water being treated. Some modern water softeners are designed to be more efficient in terms of salt usage, so they may release fewer sodium or potassium ions into the softened water.
If you are concerned about sodium or potassium levels in your softened water, it’s a good practice to periodically test your water to determine the exact levels. This will allow you to monitor and adjust your water softener settings or explore alternative water treatment methods if necessary, especially if you have dietary restrictions or health concerns related to sodium or potassium intake.
