It used to be simple. All block salt was made in standard size 4kg blocks, packed in two’s from rival brands, each of excellent quality. Some people chose to buy the brand that matched the manufacturer of their water softener, either Kinetico or Harvey, others realised they could use either. Increasingly cost conscious customers would take advantage of our bulk deals, either to store safely until needed or to divide between family, friends or neighbours.

Then the market, specially online, became flooded with cheap alternatives, previously unknown brands often made from salt of secondary quality, certainly not the Pure Dried Vacuum salt that Harveys and Kinetico are made from. Problems soon manifested including discolouration, powdery sediment, even sand and grit accumulating in brine tanks, leading to softener malfunction, engineer call-outs and water softener warranty becoming void.

As Salt-Supplies we know good salt when we see it, with over 30 experience in the salt industry and close connections to water softener manufacturers and dealerships, we’re learned a thing or two. So following the success of our Watersprite tablet and pellet salt range and it’s reputation for quality and purity over many years, it was a logical step to create a block salt using the same quality of salt. A block that’s interchangeable with standard 4kg blocks from Harvey or Kinetico, that’s widely available and that’s quality assured. So if you have a water softener that uses original 4kg blocks, we invite you to try our Watersprite block salt.
