Kinetico Block Salt

Water softener salt is a specially formulated salt used to regenerate the resin inside a water softener system. During the softening process, the resin collects hard water minerals like calcium and magnesium. The brine solution made by the salt is then used to flush these minerals away during the regeneration stage, so the system can continue to work effectively. 

Head to our guide on how water softeners work to learn more about this process. 

The amount of salt a water softener uses depends on your water hardness and household water usage. On average, one person will usually use around 4kg – or one block – of salt per month. Our Kinetico water softeners are designed to be highly efficient, only using the amount of salt needed to regenerate based on actual water usage. 

Most traditional water softeners, including our Kinetico softener systems, use a brine solution to regenerate the softening resin. There are salt-free systems available that use alternative methods, but these are generally less effective in hard water areas. For true softening and long-term protection against limescale, a salt-based system is the most reliable option. 

Block salt is designed for water softeners that are specifically manufactured to use salt blocks rather than tablet salt. Always check your water softener’s user manual or product specification to ensure you’re using the correct type of salt.

Yes. Tablet salt can be used in a block salt water softener, however, it is far more time consuming, and cumbersome. It is always best to use the salt format recommended for your specific water softener.

Store block salt in a cool, dry place and keep it in its original weather-resistant packaging until you’re ready to use it. Protecting the salt from moisture helps maintain its quality and ensures it performs effectively during regeneration.

A Kinetico Premier range water softener eliminates limescale build-up by removing hardness minerals from your water. This helps protect household appliances, improve the efficiency of boilers and heating systems, reduces cleaning time and leave skin, hair and laundry feeling softer.
