How Do Water Softener Systems Work?

Have you ever tasted your drinking water at home? Usually your tap water  is not as clean as you think and leads to bad tasting hard water (hardness minerals and contaminants) from your local water supply. Water hardness is based off the concentration of hard minerals, such as calcium and magnesium, in water. “Soft water” has very low concentration of hard minerals, while “very hard water” has a relatively high concentration of hard minerals. Using hard water can cause mineral buildup inside of your water-using appliances which can lead to long term damage. Water softening systems “soften” the hard water by removing mineral ions through a process named ion exchange. This process consists of exchanging positively charged mineral ions in the hard water with positively charged ions, leaving the softened water free of mineral ions. There are two tanks in a water softener system that facilitate this ion exchange, the resin tank (aka mineral tank) and the brine softener tank. The resin tank does the bulk of the water softening as the sodium ions from the brine solution exchange places with the mineral ions (water hardness ions). Ion exchange resin beads and water combine resulting in the hardness minerals attaching to the beads. Once all of the resin beads have been covered in hardness minerals, they are flushed out of the tank using either potassium chloride or sodium chloride. The water exiting the resin tank contains a very small number of sodium ions, but no longer contains high levels of hard mineral ions. The brine tank then recharges the resin tank through a flushing process where the resin tank is rinsed with salt water from the brine tank. The salt water saturates the resin bead, removing any stuck mineral ion and replacing them with a sodium ion. The dissolved minerals are then flushed and the system is ready to soften water again.

Benefits of Soft Water

There are many benefits of installing a water softener system in your home. 

  • Improved Plumbing – The minerals in hard water can cause a buildup while they travel through the pipes of your home. This buildup can interrupt your water flow by clogging the pipes, causing damage to your plumbing. By softening your water, you can prevent this damage and a call to your plumber. 
  • Less Soap & Detergent – Soft water makes your dish soap and detergent more effective as it penetrates and dissolves better than hard water. This helps save you money by using lesser amounts of your cleaning solutions. 
  • Cleaner DishesHard water can leave hard water stains on your plates and cutlery. By using soft, filtered water instead, you can start to appreciate cleaner, spotless dishes and utensils. 
  • Cleaner Appliances and Home- If you have hard water, you are probably familiar with the chalky lime and soap scum mineral deposits that build up on the walls of your showers, sinks, and faucets. Not only will using soft, clean water eliminate this build up, but you won’t have to spend any more of your time cleaning them.

Which Kind of Water Softener is Right for Me?

Do I go with a “salt free” or “salt water softener” (aka the commonly known water softener)? Does the softened water go into my whole home including the water heater?

Deciphering the difference between the multitude of water softening options is not easy, but we’re here to help. Depending on your level of water usage or hardness level, we may recommend different solutions. You can learn more about water softeners and the benefits HERE.
