With these hard minerals trapped by the resin beads, the water that flows onward is now soft. As hard water passes through the mineral tank, the resin beads attract the hard minerals. The beads then shed off sodium ions in exchange for the calcium and magnesium ions to make the water soft. Later, the resin beads are cleaned of buildup using a solution from a brine tank.
It also helps soaps to give a "slippery" feel to your skin when you wash. Most manufacturers of water softeners recommend that you reduce the amount of soap and detergents you use after installing a water softener. A water softener works by removing hard minerals through the ion exchange process. Systems consist of two parts —a softening tank packed with tiny resin beads and a brine tank loaded with salt.
Salt Based Water Softeners vs. Saltless Water Softeners
They will argue that any water hardness over 1 ppg requires softening. Ultimately, this is a matter of personal preference, but be aware that the official stance is that only distinctly hard water requires softening. A metered water softener regenerates based on the volume of water that flows through the system . The force of the brine flowing over the beads causes the magnesium and calcium hardness ions to be released, and sodium takes their place. Most water softeners use salt because it’s affordable, efficient, and easy to find.
A water softener is a water treatment system that softens hard water by removing certain chemicals and minerals and replacing them with sodium ions through ion exchange. Typically, regenerations can be set for every two to three days. However, there are several factors that need to be considered in determining when your water softener needs to recharge. If you own a pool or water your lawn frequently, you will need more frequent regenerations, maybe even several times a day. For everyday household activities, you won’t need as many regenerations. If you have very hard water, the resin beads in the water softener will become saturated more quickly than if your water is not especially hard.
How Does a Water Softener System Work?
Yarna Water Descaler SystemMagnetic water descalers are slightly different than water softeners. As descaling tools, magnetic water descalers help prevent the formation and buildup of scale in your plumbing pipes. We hope this guide has helped you learn more about how water softener systems work using salt.
This is the water softener regeneration cycle, and it’s why people add salt to water softeners. But problems may result if you are on a restricted low-sodium diet since a small amount of sodium is transmitted into the drinking water during the regeneration process. And sodium can also affect the bacteria in septic systems that are necessary for the breakdown of waste. For this reason, sodium brine has been banned or limited in several states and municipalities such as California. Hard water is a generic term used to refer to a water supply that has absorbed high quantities of minerals from the earth—primarily calcium and magnesium. Water is described as "soft" if it lacks these minerals in substantial quantities.
How Do I Fix Hard Water?
The control valve serves as the traffic cop in your water softener system. It determines when it is time to clean those plastic beads, which are now coated with calcium and magnesium. Older style units use a timer, while newer models use a computer-controlled meter that determines when it is time for regeneration, based on actual water usage.
In homes, we offer installation, repair, and maintenance of heating and cooling systems, plumbing, and purification systems, and we also deliver fuel oil. For businesses, we offer HVAC system services, plumbing, duct cleaning, water conditioning, chillers, geothermal, and refrigeration. A salt bridge occurs when a hard crust forms in the brine tank. This will prevent the salt from dissolving in the water to make your brine. Without the brine, the resins beads cannot do their job, so you will have hard water until the bridge is cleaned and removed. If you have hard water, a water softener is the solution to spotty dishes, dry skin and limescale buildup in pipes and appliances.
🤔 So, How Does a Water Softener Work?
When affected, the heater can produce a popping sound as the calcium or magnesium deposit attaches to the surface of the heating element. As the tanks heat and expand, the calcified rocks crack to produce that popping sound.

These beads are charged with sodium ions that have a negative charge. Since they’re opposite charges, as the hard water is passed through the resin, the beads grab the mineral ions and remove them from the water. This strips the hardness out of your water, providing soft water to your home and appliances.

They’re usually just much larger and might contain more than one tank. Other optimizations for larger-scale softeners include increased flow valves and hardier construction. All Whirlpool® Water Softeners use Demand Initiated Regeneration with Salt Saving Technology so the system only recharges when necessary, saving salt and water.
Jennifer has over 18 years of experience in the water treatment industry by providing filtration solutions for residential ,commercial and industrial clients. The water downstream of your softener – i.e. the soft water that has left the mineral tank – should have a hardness reading of less than 3 GPG . The very best high efficiency water softeners available today cost $1,200-$2,500 on average. Check out our full, detailed list of the pros and cons of water softeners here. But there are other types of hard water treatment that are rapidly gaining popularity.
The brine washes down through the resin beads, and a reverse of the ion exchange process takes place. The brine solution washes through the resin beads, replenishing them with sodium. This process repeats itself every time the water softener system regenerates. When the salt levels fall low, the brine tank will need to be topped up with more salt. Unlike ion exchange, the sodium-free water softening process creates no wastewater, a plus in drought-prone areas. It requires no brine solution and adds no sodium ions to your diet.
A water softener with a timed or metered system runs between $2,000 and $4,000. Factors that affect average water softener cost include plumbing system size, age of the building and number of users. This cycle is more efficient and uses up to 65% less water and up to 75% less salt. The process also distributes the sodium ions better than the co-current system. Magnetically-treated water is going to feel and taste different than other chemically-treated softeners.
