Harvey Mini Curve Block Salt - Discounts

£44.64
  • Details

  • Harvey Mini Curve Salt is designed for the latest Harvey water softeners, including Minimax Innova, TwinTec Cobalt, TwinTec S5 and the Harvey Arc. It is lighter and much easier to handle than the Harvey original blocks. Harvey's Curve salt blocks are 100% pure salt and safeguard your softener warranty.

    Free Delivery in Kent, Sussex & SE London. We don't deliver outside this area.

    Fair Prices Guaranteed. Our prices are always competitive. We offer big discounts compared to Harvey's Direct. Courier charges are very high for heavy packages. This is a huge cost to companies that deliver curve salt nationally. We can keep costs down because we own delivery vans and operate locally.

    Better service. Hydroworks can put your mini curve salt away and, upon request, perform a free water softener health check while we are there. Let us do the heavy lifting.

    The patented Harvey mini curve blocks are hard compressed, non-dusty, and of good uniform shape. They dissolve slowly and evenly to form a consistent brine solution. Harvey invented salt block products, and consistency, purity, and quality are guaranteed. They are only available from Harvey authorised dealers in branded packaging.

    Compliant with British Standard BS EN973, Harvey's Salt is Grade A PDV (Pure Dried Vacuum) food-quality salt. It is pure with no additives, anti-caking agents, or grit that could damage your softener.

    Each pack contains two mini curve salt blocks. A pack weighs 4.3 kg, and each block weighs 2.15kg (4lb 6oz) 

    IMPORTANT DELIVERY INFORMATION 
    Please allow up to 10 working days from the date of your order for delivery. If you are running low and need your salt delivery sooner, please let us know, and we will do our best to help you.

🧂  Why Salt Quality Really Matters

We only supply pure Grade A PDV salt — because anything less can devastate your softener.

Some salts now entering the UK market (like sea salt, lake salt, and solar-evaporated varieties) aren’t actually cheaper — but they’re packed with things your softener really can’t handle.

⚠️ Here’s what can happen with the wrong salt:

  • Seafoam builds up inside your softener. This is often caused by algae or seaweed spores that thrive in salty environments — and once they’re in, they’re almost impossible to flush out - your softener begins to breed algae because this type of algea thrives in salt water environments.

  • You’ll also get oil residue from boats and ships — this coats everything internally and causes seals to slip, meaning parts stop fitting properly.

  • And then there’s the coarse and fine sand sediment, which can scratch the valve and damage precision components.

In short? It’s not worth the risk. 

✅ Using Pure PDV Grade A salt protects your machine.

❌ Using poor-quality salt will invalidate your manufacturer’s guarantee — and could cost you far more than you save.

💡 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 - probably because it increases servicing costs and reduces equipment life which means more profit for them sooner.


🧰 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.


🚚 Delivery Information
