Tip! For the best water softener performance, top up your salt before it runs out completely. Most softeners work best when the brine tank stays at least one third full. Check your tank monthly and add a fresh bag of Granulite Granular Salt to keep your water consistently soft, your appliances scale free, and your laundry, skin and hair feeling great.
Note: store your Granulite Granular Salt in a dry place. The bag is moisture resistant but prolonged exposure to damp conditions can cause granules to bond together, which slows dissolution inside the softener.

Frequently Asked Questions
Is Granulite Granular Salt suitable for all water softeners?
Granulite works with all granular salt water softeners on the UK market, and is also suitable for dishwashers that require granular salt. It is not designed for tablet salt or block salt systems, those models require a different format. Check your softener manual if you are unsure which type your unit takes.
How is Granulite different from other granular salts?
Granulite is made by crushing and compacting PDV salt into firm 2 to 6mm granules, while traditional granular salts consist of loose crystalline beads. The compacted structure means less dust when pouring, a more consistent granule size, and slower more controlled dissolution inside the brine tank.
What does PDV salt mean and why does it matter?
PDV stands for Pure Dried Vacuum salt, a manufacturing process where brine is evaporated under reduced pressure to remove impurities and produce exceptionally pure salt crystals. The result is high purity sodium chloride that dissolves cleanly and protects the internals of your softener.
What is BS EN 973 certification?
BS EN 973:
2009 is the British and European standard for chemicals used in the treatment of water intended for human consumption. Granulite meets this standard, which means the salt has been tested and verified safe for use in water softening systems that supply drinking water.
Can I use Granulite as dishwasher salt?
The high purity and granule size make Granulite suitable for use as dishwasher salt. It prevents limescale build-up inside your dishwasher and gives spot free glassware over time.
How often should I top up the salt in my water softener?
Most UK households need to add salt every 4 to 6 weeks, but heavy water users or hard water areas may need to top up more often. Check the brine tank monthly and add a fresh bag before the level drops below one third full.
How fast is delivery?
We deliver within 48 hours across the UK. Free UK delivery applies on orders over £20, so a single 25kg bag qualifies automatically.
