Why Choose Harvey Block Salt Over Cheaper Alternatives?
Harvey’s Block Salt stands out from cheaper brands for its superior quality and performance. Our engineers have found that using cheap, impure block salt can cause damage to water softeners. These lower-quality salts often contain grit and oil, which settle at the bottom of the machine and can harm sensitive components. Unfortunately, using such salts voids the 10-year warranty we offer on our water softeners. If you find salt blocks significantly cheaper than ours, they are likely of lower quality and could risk damaging your machine.
Compatibility
Harvey Block Salt is compatible with a range of water softeners, including Harvey, Kinetico, Twintec, Crown, BWT, and Monarch models. However, if you own a Minimax Innova, TwinTec Cobalt, or Harvey Arc, you must use Harvey Curve salt blocks.
Are Salt Blocks Better for Water Softeners?
For machines designed to use block salt, this is the most appropriate option. Salt tablets can create undissolved sludge at the bottom of the tank, increasing the need for maintenance. In contrast, block salt dissolves evenly, as it remains just below the water line and leaves no residue. It also stops dissolving once the brine tank reaches a saturation point, ensuring efficient usage.
The Harvey Block Salt Advantage
Harvey is a leading name in the UK water softener industry, having invented block salt for the UK market. Known for its high quality and purity, Harvey Block Salt ensures perfectly softened water. It complies with British Standard BS EN973 and is made from Grade A PDV (Pure Dried Vacuum) food-grade salt, with a purity level of 99.6% - 99.9%.
Harvey Block Salt is compatible with all older-generation block salt softeners, as well as tablet salt softeners that can also use blocks. It is particularly suited for Kinetico water softeners, including the 2020c, AquaBlu, and Compact models.
How Much Salt Will My Softener Use?
Salt consumption varies depending on your water usage and the hardness of your local water. We expect about ¾ of a salt block to be used per person per month, based on Kent and South East London water hardness.

💎 Why the quality of Salt is important
We only supply pure Grade A PDV salt — because all water softeners needs that quality to survive. Salt purity is essential to keeping your system running smoothly and lasting longer.
As the UK salt market grows, we’ve seen more sea and lake salt creep in. It’s not necessarily cheaper — but it will bring both coarse and fine sand sediment, sea foam (algae growth), and oily residue into your system, which will damage your softener’s valve, and potentially your home.
If you would like to read more on this very important subject, please look at this page which I have written which is within the Learning Hub.
🛑 Important: Using poor-quality salt will invalidate your softener’s guarantee.
💡 Switching from Granular Salt?
If you’ve been using granular salt, now’s the time to switch.
Tablet salt is far better for your machine — it reduces wear and tear and helps extend its life. The only people who sell and recommend granular salt either don't know how damaging it can be, or don't care.
🧰 FREE Water Softener Health Check
When we deliver your salt, we’ll happily check over your water softener, completely free-of-charge. Just let us know when placing your order.
