Hard water is treated in a water softener using a technique called "ion exchange". This works by passing the hard water through a tank of tiny resin beads coated with sodium ions. As the water flows through the system, the calcium and magnesium ions in the water are exchanged for the sodium ions, yielding soft water.
The beads in your water softener must be periodically flushed, or regenerated, to keep the system functioning. This is typically done using a brine (salt and water) solution that is stored in a tank beside your system. We provide a salt filling service to help keep your brine tank stocked and your water soft.
