How does it work?
A water softener works by passing the incoming hard water through a sealed container called a resin vessel, which contains literally thousands of small ion exchange resin beads.
These beads attract and retain any hardness in the water i.e. scale and scum, that causes so much damage to your system. When these beads become saturated with hardness, they need cleaning and regenerating for continued use. This is done by rinsing them with a weak solution of brine (salt and water).
The brine together with the previously collected hardness is then automatically flushed down the drain. This process takes place automatically as determined by the softener, with all the homeowner having to do is ensure the softener is kept full of salt. The softener model will determine the type of salt to be used. This is normally either tablet salt or block salt, both are available from a local plumber’s merchant, or the original softener installer.
