Free Delivery in Kent, Sussex & SE London. We don't deliver outside this area. Harvey's direct price is £47.50 for ten packs. We offer multipacks of 10, 20, 30 or 40 curve blocks at very competitive prices. Why are we the cheapest? Courier charges are very high for heavy packages. This is a huge cost to companies that deliver nationally. We can keep costs down because we have our own delivery vans and operate locally.
Better service. Hydroworks can put your curve salt away and do a free water softener health check by request while we are there. Let us do the heavy lifting.
The bijou Harvey Mini-Curve Block Salt is designed for the latest generation of Harvey water softeners, including Minimax Innova, TwinTec Cobalt and Harvey Arc. They are lighter-weight than the Harvey original blocks and much easier to handle. Harvey's mini-curve salt safeguards your softener warranty.
The patented curve blocks are hard compressed, non-dusty and of good uniform shape and dissolve slowly and evenly to form a consistent brine solution. Harvey invented salt block products, and consistency, purity and quality are guaranteed.
Compliant with British Standard BS EN973, Harvey Mini Curve Block Salt is Grade A PDV (Pure Dried Vacuum) food quality salt, pure with no additives, no anti-caking agents or grit that could damage your softener.
Each pack contains two salt blocks. A pack weighs 4.3 kg, and each block weighs 2.15kg (4lb 6oz)

All the water softener salt we sell is pure Grade A PDV quality.
The purity of your water softener salt is critical to preventing damage to your softener and reducing product life.
As the salt market in the UK grows, we are seeing more sea & lake salt entering the UK market. It’s not being sold any cheaper than the top-quality Harvey product but brings with it several problems:
Fine sand sediment, which can scratch the valve of a water softener, and
Seafoam can fill the cylinder and create areas within it that are very difficult to regenerate and, therefore, can lead to hard water, and
An oil residue from impurities in the water can coat the valve of the softener and prevent the efficient working of the unit, resulting in hard water.
The use of poor-quality salt will invalidate most manufacturer guarantees. Therefore, we guarantee the best salt purity when ordering your salt from Hydroworks. Read more about the importance of salt purity.
If you have been buying granular salt, please instead order 25kg tablet salt or 10kg tablet salt, which is much better for your water softener as it reduces wear and tear and improves the life expectancy of your machine.
