This continues until just before the resin bed is exhausted and need recharging. Typically
the resin bed will be automatically recharged 2 or 3 times a week using a brine
solution. This will occur @ 2:00am on the days it needs to.
It is important to note that brine made from salt does not soften the
water, it is just used to recharge the ion-exchange resin bed media inside the
water softener that does the actual softening and then ends up down the drain.
Unlike naturally occurring soft water, softened water has exactly the same
amount of dissolved solids as hard water. All we have done is exchanged calcium
and magnesium metal ions that cause scale and soap scum for sodium metal ions that do not.
Salt is added to the water softener about once per month and the Ensign water
softener will alert the user when the salt is running low and requires refilling
within about 7 days.
Modern installations typically have a third hard water mini tap or a new 3-way sink tap fitted as part of the installation.
