The only maintenance your water softener should require is adding salt. How often you replace your salt depends on your water usage. We recommend you’ll need approximately one block of salt per person, per month. Simply lift the lid on the unit and check the salt usage every week. As an Authorised Kinetico Dealer, we recommend you use Kinetico Block Salt in your water softener which is available in various pack sizes, hassle-free and easy to load into your unit.
